Brazil Bugs #5 – Lagartixa

On my third night here in Campinas last week, I went out to check the building lights around the hotel grounds.  Surely a fantastical assortment of gaudy, tropical insects would be awaiting me on this hot, humid, summer night in southern Brazil.  Alas, virtually no insects were to be found anywhere – on the walls, in the window sills, under the street lights, or crawling on the sidewalks.  A disappointment, although I’m loathe to complain too much considering the number of insects I’ve encountered during the daylight hours.  I did find a gecko on the hotel wall, however, and although it is not a “bug” the lack of insects at the lights made a photography subject by default.

I’m not at all an expert on reptiles, and certainly those in South America, but I can’t help wondering if this is Hemidactylus mabouia – the tropical house gecko, or lagartixa-doméstica-tropical – an African species introduced to the New World and now widespread from the southern U.S. through much of South America and the Caribbean.

BitB Top 10 of 2010

Welcome to the 3rd Annual BitB Top 10, where I pick my 10 (more or less) favorite photographs of the year.  My goal for 2010 was to continue the progress that I began the previous year in my quest to become a bona fide insect macrophotographer.  I’m not in the big leagues yet, but I have gotten more comfortable with using my equipment for in situ field photographs and am gaining a better understanding of lighting and the use of flash.  I also began experimenting with different lighting techniques (e.g. white box) and diffusers and am putting more effort into post-processing techniques to enhance the final appearance of my photographs.  I invite you to judge for yourself how successful I’ve been toward those goals by comparing the following selections with those from 2009 and 2008 – constructive feedback is always welcome:


Best Tiger Beetle

Cicindela denverensis - green claybank tiger beetle

From ID Challenge #1 (posted December 23).  With numerous species photographed during the year and several of these dramatic “face on” shots, this was a hard choice.  I chose this one because of the metallic colors, good focus throughout the face, and evenly blurred “halo” of hair in a relatively uncluttered background.


Best Jewel Beetle

Buprestis rufipes - red-legged buprestis

From Special Delivery (posted July 13).  I didn’t have that many jewel beetles photos to choose from, but this one would have risen to the top no matter how many others I had.  The use of a white box shows off the brilliant (and difficult-to-photograph) metallic colors well, and I like the animated look of the slightly cocked head.


Best Longhorned Beetle

Desmocerus palliatus - elderberry borer

From Desmocerus palliatus – elderberry borer (posted November 18).  I like the mix of colors in this photograph, and even though it’s a straight dorsal view from the top, the partial dark background adds depth to the photo to prevent it from looking “flat.”


Best “Other” Beetle

Enoclerus ichneumoneus - orange-banded checkered beetle

From Orange-banded checkered beetle (posted April 22).  The even gray background compliments the colors of the beetle and highlights its fuzziness.  It was achieved entirely by accident – the trunk of the large, downed hickory tree on which I found this beetle happened to be a couple of feet behind the twig on which it was resting.


Best Non-Beetle Insect

Euhagenia nebraskae - a clearwing moth

From Euhagena nebraskae… again (posted October 21).  I photographed this species once before, but those photos failed to capture the boldness of color and detail of the scales that can be seen in this photo.


Best “Posed” Insect

Lucanus elaphus - giant stag beetle

From North America’s largest stag beetle (posted December 30).  I’ve just started experimenting with photographing posed, preserved specimens, and in fact this male giant stag beetle represents only my second attempt.  It’s hard to imagine, however, a more perfect subject than this impressively stunning species.


Best Non-Insect Arthropod

Scolopendra heros - giant desert centipede

From North America’s largest centipede (posted September 7).  Centipedes are notoriously difficult to photograph due to their elongate, narrow form and highly active manner.  The use of a glass bowl and white box allowed me to capture this nicely composed image of North America’s most spectacular centipede species.


Best Wildflower

Hamamelis vernalis - Ozark witch hazel

From Friday Flower – Ozark Witch Hazel (posted March 26).  The bizarre form and striking contrast of colors with the dark background make this my favorite wildflower photograph for the year.


Best Non-Arthropod

Terrapene carolina triunguis - three-toed box turtle

From Eye of the Turtle (posted December 10).  I had a hard time deciding on this category, but the striking red eye in an otherwise elegantly simple photograph won me over.  It was also one of two BitB posts featured this past year on Freshly Pressed.


Best “Super Macro”

Phidippus apacheanus - a jumping spider

From Jeepers Creepers, where’d ya get those multilayered retinae? (posted October 5).  I’m not anywhere close to Thomas Shahan (yet!), but this super close-up of the diminutive and delightfully colored Phidippus apacheanus is my best jumping spider attempt to date.  A new diffuser system and increasing comfort with using the MP-E lens in the field at higher magnification levels should allow even better photos this coming season.

Eye of the Turtle

Adult male three-toed box turtle (Terrapene carolina triunguis).

Is there anything more lovable than the humble turtle?  As old as the dinosaurs, they stumbled onto a body plan that works and promptly dropped out of the evolutionary arms race.  Slow, plodding, and seemingly oblivious, they steadfastly cling to their quite, unhurried lives.  As the rest of the earth’s diversity of life races on, turtles go about their business much as they have done for more than 200 million years now.  They are survivors.

My friend Rich and I encountered this three-toed box turtle (Terrapene carolina triunguis) during our hike of the lower North Fork Section of the Ozark Trail in extreme southern Missouri.  Three-toed box turtles are one of four U.S. subspecies of the eastern box turtle, occupying the area west of the Mississippi River from Missouri and Kansas south to Texas and distinguished by their largely unpatterned shell and – yes, three toes on the hind legs rather than four.  I walked right by this guy the first time without noticing him, and only when I turned around to go back and look at something else did I see him sitting there – neck fully extended.  Box turtles exhibit considerable variability in color and patterns on the head and neck, and this particular individual is one of the more conspicuously colored that I’ve seen.

And the eye – as red an eye as I’ve ever seen!  Almost surely a male, as females may have some red in the eye but rarely to such a spectacular degree.  Also likely full-grown based on his rather large size, though probably not too advanced in age yet since the growth rings were still easily visible (in older turtles the growth rings gradually wear smooth).  I estimated it at about 12 years based on ring counts – still a far cry from the 30-50 years that are not uncommonly documented.  He kept a watchful eye on me as I studied him, and I wondered about what his future held.  As an adult, he has settled into a small home range from which he rarely ventures – likely visible to me in its entirety from where I stood.  For the next several decades, he will amble across this single hillside on an endless quest for earthworms, strawberries, and mushrooms.  Save for a possible run-in or two with a destined-to-be-frustrated coyote, fox, or racoon, it will be a largely uneventful life.  He is a survivor.

A Horridus Birthday

For many years now, I’ve celebrated my birthday each year with the “season-opener-birthday-bug-collecting-trip.”  This happens regardless of what day of the week it falls (although two years ago I did get roped into a business trip – I made up for it by stumbling into a quick but thoroughly enjoyable tour of Pipestone National Monument before my flight back home).  Last year I made sure I got the day off and had a nice, festive (tiger beetle) birthday.  For this past April 23rd, a Friday, I celebrated my 29th birthday (for the 2-dozenth time!) by grabbing long-time field companion Rich and shooting down to Sam A. Baker State Park in the Ozark Highlands of southeastern Missouri.  My goal for the trip was to find the very uncommon Cladrastis kentukea (American yellowwood), a small tree that is known to occur in Missouri only in the White River Hills of the extreme southwest and in a few localities in and near Sam Baker State Park.  Actually, it wasn’t the tree so much that I was after, but a small jewel beetle – Agrilus cladrastis – that utilizes this plant exclusively for its larval host. To date, the only Missouri specimens of this species have been collected by the late, great Gayle Nelson on yellowwood in the White River Hills, and I wanted to see if I might be able to find it in southeastern Missouri as well.  April is still too early to encounter active adults, but my plan was to: 1) find examples of the tree, 2) collect dead wood from them, and 3) cut living branches to leave in situ for infestation this season and retrieval the next.  Long story short, I succeeded on all three counts (though I won’t know for a few weeks whether the wood I brought back actually harbors any as yet unemerged adults – finger crossed!).

The area where we expected to find the tree was steep, rocky slopes overlooking Big Creek on the north side of the park.  Rich and I were hiking a trail below the slopes, and I had gotten a little bit ahead of him when I saw a 30″ long snake stretched straight out across the trail.  Recognizing it immediately as one of our venomous species, but not quite sure which one, I blurted out, “Wow, what a gorgeous snake!”  Rich, a better herpetologist than I, shouted from a distance back, “What kind?”  In the few seconds during which this exchange was taking place, it all registered – the dark stripe behind the eye, the bold markings (too dark for a copperhead, too big for a western pygmy rattlesnake, too widely spaced for a massasauga), the black tail (not yellow-green like a juvenile copperhead), and a tiny little one-chambered rattle!  I yelled back, “A young timber rattler!”  Rich got there promptly, and we decided that it must be a yearling based on the time of year, its length, and the size of the rattle.

I have seen a few timber rattlesnakes (Crotalus horridus) in Missouri over the years, but never like this.  My previous sightings have all been fleeting glimpses after hearing them shooting into the underbrush to escape my close approach – me oblivious to their presence until it was too late.  This young snake, by contrast, didn’t flinch as I approached (carefully), set down the backpack, and assembled the camera to begin taking photographs.  As I began taking a few photos of the head area (from a respectful distance – the vision of that terrifyingly aggressive prairie rattlesnake from two years ago still lingers), it became agitated and started moving for cover.  Rich wasn’t too anxious to head it off at the pass, but I wasn’t satisfied with the shots that I’d gotten so far, so I grabbed my net to block it from disappearing into the litter.  That caused it to pause just long enough for me to get back into position and frame a shot… that I couldn’t get off before it started moving again!  We did this a few times until it finally just crawled right into the net – now what?!  I carried the net over to some large rocks on the side of the trail and used them to flip the net and dump out the snake, which immediately headed for cover underneath the rocks.  I figured the photo shoot was over then, but the space under the rocks was not deep, and after a bit of probing for escape routes the snake eventually settled into a money pose and I was able to snap away with glee – what do you think?

Missouri has five venomous snake species, all of which are pit vipers with three being rattlesnakes.  I’ve featured two of these in previous posts – the Osage copperhead and the western pygmy rattlesnake.  Both of these species occur throughout the Ozark Highlands, although the latter is more common in the southwestern part of the state.  The third rattlesnake species in Missouri, eastern massasauga, is rare in wet habitats scattered across northern Missouri, while the cottonmouth (or water moccasin) is limited to stream, river, and swamp habitats in the southern Ozarks and southeastern lowlands.  Many internet references list the western massasauga also as occurring in Missouri, but this subspecies is not included in the most recent Snakes of Missouri (Biggler and Johnson 2004).  Within Missouri, timber rattlesnakes have a statewide distribution, but they have been extirpated by humans from many areas and now occur as small populations in scattered locations across the state.  The same is true in other parts of their range as well, particularly along the western and northern limits.  It is thus a rare and exciting treat to see one of these magnificent animals, although the reasons for its rarity are both sobering and maddening.

Rough Green Snake

My string of good herp luck looks like it might continue in 2010.  You may recall the super-aggressive prairie rattlesnake and uncooperative dusty hognosed snake that I featured in 2008 (or not – my readership was rather minuscule back then), followed by the juvenile Osage copperhead, gorgeous male eastern collard lizard, bizarre Texas horned lizards, death-feigning western hognosed snake, super rare Florida scrub lizard, and – finally – cute little western pygmy rattlesnake in 2009. All but the copperhead and collared lizard were first-time sightings for me, and now in 2010 I have yet another first-time sighting to present – the rough green snake (Opheodrys aestivus aestivus).

Rough green snake (Opheodrys aestivus aestivus)

My friend Rich and I spotted this long and slender snake during our early April hike of the lower Wappapello Section of the Ozark Trail (soon after photographing the jumping spider). We would never have seen it, so effective was its green camouflage, had it not been disturbed by our close approach along the trail and tried to flee.  The moist bottomland habitat where we found it was thick with greenbrier (Smilax sp.), making tracking the snake a thorny affair, but I managed to head it off and start taking a few photos of it.  It was surprisingly calm during the early part of the photo session, but I just wasn’t getting the lighting and exposure that I wanted.  Eventually, it started fleeing again, and my efforts to rip through the greenbriers to stay close became too much for my arms to bear.  When it started climbing a tree, I said “enough is enough” and captured him, brought him back out to the comfort and openness of the trail, and had Rich hold him while I worked on getting some better photographs.  The one above is my favorite of the bunch.

Rough green snakes are found in Missouri primarily south of the Missouri River in the Ozark Highlands, where they feed on insects such as grasshoppers, crickets, and especially smooth caterpillars.  A second green snake occurs in Missouri as well, the smooth green snake (Opheodrys vernalis), which differs from the rough green snake by having smooth scales and a more northern distribution within the state. Sadly, the smooth green snake has not been seen in the state for a number of years now, probably because of loss of habitat resulting from the near complete agricultural conversion of that part of the state.

Photo Details: Canon 100 mm macro lens on Canon 50D, ISO 400, 1/60 sec, f/4.5, Canon MT-24EX flash w/ Sto-Fen diffusers. Minimal post-processing.

The Inexorable March of Spring!

Granted, the progress of spring seems to advance in halting baby steps with occasional falls onto its muddy bottom, rather than as a determined forward march, but spring is welcome, no matter how it arrives. When little green tips start poking up and there’s a bit of that “spring smell” in the air, I simply must get out and catch up on the status of Nature — the old-fashioned way (she doesn’t have a Facebook account). Over the last week, I’ve gone forth in search of signs that everything else living is about as tired of winter as I am, and wants to get this spring show on the road! There is already so much happening, I can’t recount it all here — A partial list of unphotographed notables: owls breeding; hawks nesting; woodcocks doing their silly, repetitive and almost invisible (because it’s nearly dark) courtship displays; wood ducks on forest ponds; year-round resident songbirds reestablishing territories; spring peepers, chorus frogs, wood frogs and southern leopard frogs singing, especially in the fishless ponds; winter crane flies and midges swarming in sun flecks in the woods; wild filberts, silver and red maples flowering, etc…

Formica pallidefulva sniffs the spring air


Of course, I look for the first ants out at this time of year, though with the exception of 10 March, when the temperature exceeded 70F, they haven’t been notably active. However, that afternoon I encountered, among others, a worker of Formica pallidefulva poking its head out cautiously to sniff the spring air. This is one of my favorite local ants — largish (5-6mm), abundant, active in daylight even when it’s hot, usually shiny bronzy red to red-brown, usually with a darker gaster (the apparent abdomen of ants) around here, but ranging from a beautiful reddish gold (in the deep South) to almost pure black-coffee brown (New England and southern Canada) across its wide geographic occurrence (Rocky Mountain foothills of Wyoming to New Mexico, all the way east to Québec and Florida). It has the added charm of being the host species to a wide range of social-parasitic and dulotic (“slave-making”) ants both in its own and in another closely related genus, with which it lives in temporary or permanent mixed colonies (as with the Polyergus illustrated in my last post). The image below of these ants bringing home a charred earthworm was taken almost one year ago, as one of Shaw Nature Reserve’s prairie areas was beginning to resprout after a prescribed burn a few weeks earlier. Ants will take their food raw or cooked!

Formica pallidefulva with charred earthworm


Prenolepis imparis alate in the clutches of a gerrid

Another ant I mentioned last time I was with you, Prenolepis imparis, has the distinction of being the only ant in our fauna that has mating flights while there is still a good chance of frost in the forecast for the next few weeks. In this picture of a mating pair at  BugGuide, note the size difference that inspires their name “imparis”, Latin for disparate. Any time after mid-February when it is sunny and not too windy, and the temperature rises above 65F, the winged males and females reared the preceeding fall, fly out to partake of a grand insectan orgy. Typically, they have big flights on the first couple of appropriately warm days, then some smaller ones (i.e., fewer individuals participating) over the next few weeks. The flying males look like gnats, bobbing up and down in drifting swarms, a few feet off the ground over a shrub, near a woodland edge or in a sunny opening. (One of my co-workers got into the midst of a group of such swarms once when we were conducting a prescribed burn in a wooded area, and I recall her commenting she “felt like Pigpen with all the little bugs flying around”!) The much larger, golden-brown females lift slowly off the ground, fly ploddingly (or is it seductively?) through the male swarms, are there mobbed by the tiny fellows, and then glide away and slightly downward, mating in flight with the winner of the males’ tussling. Rather clumsy fliers, the females do not always land in a good spot, as occurred to this hapless one that ended up as a feast for a water strider. Those that survive break off their wings, dig a burrow, seal themselves in, and raise a small brood of workers on food produced in their own bodies (like say, milk in mammals or “cropmilk” in doves and some other birds.)

But lest you to think I only have eyes for ants, I feel indeed fortunate to have encountered a tarantula this week, of the same species as Ted recently posted and I didn’t even have to go to Oklahoma for it. This bedraggled individual was at the mouth of its completely flooded burrow in what is most often a very dry habitat — a dolomite glade. Stunned and muddy at the time, my guess is this creature, belonging to a resilient and ancient lineage, will dry off, clean up, and saunter away as soon as she warms up.

Aphonopelma hentzi in flooded burrow


And speaking of emerging from flooded burrows, how about this handsome fellow, a male three-toed box turtle, his sex revealed by his bright orange and red markings, coming up for a breather? In truth, it was perhaps only just warm enough to make him need air, but not really enough so for him to be up and about, so he just sat there, nearly immobile, looking pretty, notwithstanding mud and leaves glued onto his shell.

House of Herps #2

House of HerpsWelcome to the 2nd issue of House of Herps, the monthly blog carnival devoted exclusively to reptiles and amphibians.  The brainchild of Amber Coakley, (Birder’s Lounge), and Jason Hogle (xenogere), this new blog carnival had an auspicious start with the inaugural issue and its 21 contributions – an impressive level of participation for a new carnival.  This month the carnival moves off-site, and I am honored to serve as the first off-site host.  The enthusiasm continues with issue , for which I received 22 submissions from 18 contributors.  Ever the taxonomist, I present them to you below grouped by traditional classification¹.

¹ It should be noted that modern classification has “evolved” substantially from this traditional classification due to the advent of DNA molecular analyses. For example, lizards are a paraphyletic grouping, and even the class Reptilia has been subsumed within a broader class containing dinosaurs and birds. I stick with the traditional classification here for reasons of familiarity and convenience.

Class AMPHIBIA (Amphibians)
-Order CAUDATA (Salamanders)

California Giant Salamander (Dicamptodon ensatus).  At the nature of a man, Ken talks about not one, but two close encounters last fall with this otherwordly-looking creature.  The first one he saw was a monster of a salamander, measururing a whopping 12 inches (30 cm) in length as it brazenly lounged on a mountain bike trail.  Remaining docile for photographs, imagine Ken’s surprise when the salamander started barking at him when he picked it up to move it to safer ground!  In his second encounter, he got to watch one chomp down on a banana slug – mmm tasty! 

-Order ANURA (Frogs)

Upland Chorus Frog (Pseudacris feriarum).  At Anybody Seen My Focus?, Joan normally only gets to hear the breeding season calls of the chorus frog and his friends who have taken up residence in the water-filled bathtub that serves as a planter in her greenhouse, usually bobbing under the water upon any approach.  But on this occasion, he agreed to photographs, even allowing a final closeup.

Gulf coast toad (Bufo nebulifer).  At Dolittle’s Domain, Dr. Doolittle marvels at one of the many toads that she has found parked under the outside light all night (along with the bats and armadillos) during the cold darkness of December.  Rather than fleeing the camera flash in the face, he simply hunkered down trying to make himself flatter, apparently thinking that would make him invisible and not realizing that he just looked fatter!

Northern Cricket Frog (Acris crepitans).  HoH‘s own Jason weaves artful writing with stunning photographs to distinguish one of the smallest land vertebrates in North America at xenogere.  Despite their ubiquity, these little frogs often go unnoticed due to the smallness of their size, their impressive leap, and their extreme variability.  Get a good look at one, however, and you might notice a key feature or two.

American Bullfrog (Rana catesbeiana).  At Willow House Chronicles, barefootheart looks at frogs on the opposite end of the size spectrum, in fact North America’s largest frog living in an increasingly naturalized man-made pond in eastern Ontario.  These behemoths are more frequently heard than seen by their distinctive “yelp” and splash in response to being approached.  If you are lucky enough to get as good a look as barefootheart did, you might be able to distinguish male from female by looking at its eyes, ears, and throat.

Class REPTILIA (Reptiles)
-Order TESTUDINES (Turtles)

Common Snapping Turtle (Chelydra serpentina).  We have three contributions dealing with these grizzled, ancient, grotesquely beautiful reptiles.  The first one comes from Michelle at Rambling Woods, who shows us how it is possible to tame your pet common snapper (but only to a certain degree).  If her story isn’t enough, she also presents a short video clip on the common snapping turtle (Baby snapping turtleREMEMBER – don’t ever try to catch or hold a snapping turtle with your bare hands!).  In another post, HoH‘s own Amber talks about her attempts to rescue a snapping turtle at Birder’s Lounge.  Fortunately for Amber, the little guy was just a tot – not nearly big enough to prune a digit and thwart Amber’s display of compassion.  It’s amazing how a creature so dinosaurian at maturity can still be so cute as a youngster.  In the third contribution about these fascinating creatures, Marge at Space Coast Beach Buzz talks about her snap (get it?) decision to adopt one of these animals, only to change her mind after discovering its true identity (and before losing any fingers).

Green Sea Turtle (Chelonia mydas).  David at Living Alongside Wildlife notes that while green iguanas falling from trees were a popular news report from the unusual cold snap experienced in the southeatern U.S. last month, they were not the only reptiles so adversely affected.  Sea turtles, populations of which have already been compromised by loss of nesting sites, fishing practices, and trash pollution, also found the coastal waters too cold for normal function.  While natural hardships may be nature’s way, he argues (quite effectively) that it is our responsibility to help mitigate their effects considering the perilous position in which we’ve placed these majestic animals to begin with.

Eastern Box Turtle (Terrapene carolina).  Two contributors submitted posts about these lovable oafs.  At A DC Birding Blog, John posted a photo of a box turtle seen at Brigantine Beach.  He wonders if their always disgruntled look is a result of him disturbing from their activities.  These turtles are easily identified by their bright markings – usually dark brown or olive-colored with bright orange or yellow patterns, dome-shaped carapace, and hinged plastron (bottom part).  Individual turtles have unique designs on their shells, making them identifiable in the field.  Turtles can get worms, believe it or not, and Celeste at Celestial Ramblings adds them to the growing list of animals that she has had to de-worm (including herself, ick!).  Step-by-step instructions and explicit photos combine to show that this is not an easy job, requiring no less than three people – “just another day at the office.”  Hmm – cats look easier!

Diamondback terrapin (Malaclemys terrapin).  The diamondback terrapin is the only species of turtle in North America that spends its life in brackish water (salty but less so than sea water).  At Kind of Curious, John describes efforts by The Wetlands Institute to prevent vehicle mortality caused by terrapins crossing roads in their attempt to reach higher ground for laying eggs.

-Order SQUAMATA
–Suborder LACERTILIA (Lizards)

Common collared lizardCommon Collared Lizard (Crotaphytus collaris).  From Jill at Count Your Chicken!  We’re Taking Over! comes this delightful encounter with one of North America’s most charismatic lizards.  I’ve had my own experiences with these guys, but I’ve never gotten one to crawl on my hat or – even better – gotten one to pose with me for a photograph!

Prairie Lizard (Sceloporus consobrinus).  Near my backyard, Marvin at Nature in the Ozarks presents a nice compendium of this species complimented with beautiful photographs.  Marvin not only discusses identification, distribution, life cycle, habitat, and food, but also comments on the recent DNA molecular analyses that have resulted in a reclassification of the former polytopic “fence lizard” and split up the many subspecies into full-fledged species – a man after my taxonomic heart!

“Culebrilla ciega” (Iberian Worm Lizard) (Blanus cinereus).  Javier at macroinstantes writes an artful blog focusing on natural history of the Iberian Peninsula (it is written in Spanish, but Google can easily translate to English for those who need it).  In this post, he presents extraordinary photographs of this subterranean reptile that is endemic to the Iberian Peninsula.  Traditionally classified in the family Amphisbaenidae, it is now considered to belong to its own family the Blanidae.

“Lagartija de Valverde” (The Spanish Algyroides) (Algyroides marchi).  Javier (macroinstantes) also writes about this small lizard that was only discovered in 1958.  With a global range limited to a few mountain streams in a mountainous area of southern Spain covering less than 2,000 km², it is clasified as endangered on the IUCN Red List.  Like so many of the world’s reptiles, its severely fragmented population is suffering declines due to continuing habitat degradation.

–Suborder SERPENTES (Snakes)

Western Rattlesnake (Crotalus viridis).  On the Colorado front range, Sally at Foothills Fancies had three encounters with this aggressive species on her property.  Fortunately, Sally has a “nonagression treaty” with rattlesnakes and allows them to go about their business as much as possible.  Those that get too close for comfort are humanely relocated rather than simply dispatched.  Sadly, many of Sally’s neighbors are not quite so understanding.

Texas Indigo Snake (Drymarchon corais erebennus).  These snakes do not have any such nonaggression treaty, and David at Living Alongside Wildlife contributes another piece illustrating the rattlenake-eating capabilities for which Indigo snakes are famous.  The photographs in the post show a large individual consuming a Western Diamondback Rattlesnake. David explains how these snakes are often identified as blacksnakes and reveals the characters visible on predator and prey that allow their correct identification.

Black Rat Snake (Elaphe obsoleta).  Right here in my home state, Shelly at Natural Missouri characterizes black rat snakes as one of the most commonly encountered snakes in Missouri.  Large snakes reaching up to 6 feet in length, they often end up in basements and cellars in the fall in search of a place to spend the winter – just in time for Halloween!  These snakes are often needlessly killed because of their resemblance to the venomous cottonmouth or water moccasin that they superficially resemble.  However, Shelly has the same nonaggression treaty with these snakes that Sally has with rattlesnakes (although her husband is not quite so sympathetic). 

-Order CROCODILIA (Crocodilians)

American Alligator (Alligator mississippiensis).  David at Living Alongside Wildlife also contributed two pieces on North America’s largest reptile.  In his post Gatorzilla, he examines commonly e-mailed pictures and text about so-called “giant” alligators, debunking myths about 25 foot long monsters, clarifying the identity of misidentified Nile crocodiles, and exposing cases of camera trickery.  In his post Mommy Dearest, he recounts his nervewracking experience when he stumbled upon an alligator nest while knee deep in a south Georgia swamp at night.  Worse, the babies had hatched!  Read the post to see if David got out of there with both of his legs.

GENERAL HERPETOLOGY

Sometimes simply the act of looking for herps is as enjoyable as the herps that are found.  However, it has been a tough January for Bernard at Philly Herping.  A particularly cold snap in the first half of what is already the coldest month of the year made herping at his favorite cemetary a lesson in futility.   I hope you notice the irony – cemetary?, no sign of life?, cold-bloodedness (okay, okay – ectothermic)?

I hope you’ve enjoyed this issue of House of Herps.  The February issue moves over to xenogere, where Jason’s considerable carnival hosting talents are sure to be on full display.  Submit your slimy, scaley, cold-blooded contributions by Febrary 15, and look for the issue to appear by February 18.

BitB Best of 2009

In my first post of 2009, I looked back at the photographs I had posted during 2008 and picked some of my personal favorites. I hesitated then to call myself a photographer (and still do), but I at least now have suitable equipment to aid in my progress toward that eventual goal. I have learned much over the past six months in my first attempt at serious insect macrophotography (prioritizing in situ field photographs of unmanipulated subjects as a matter of personal choice).  Through this, I’ve come to realize the following skills to be the most important for success:  

  1. Composition
  2. Understanding lighting
  3. Knowing how to use a flash
  4. Knowledge of the subject

I’ll give myself a “A” in the last of these, but in the other areas I still have much to learn. With this caveat, and for the last post of 2009, I offer the following twelve photographs as my final choices for the 2nd Annual “Best of BitB”:  

Best beetle

Cylindera celeripes (swift tiger beetle), Woodward Co., Oklahoma

From Revisiting the Swift Tiger Beetle – Part 1 (June 30).  A decent enough photograph, especially considering that I’d had my camera for about a month when I took it.  However, the discovery of robust populations of this formerly rare and enigmatic species throughout northwestern Oklahoma (and later also in northwestern Missouri) was the most significant find of the 2009 field season, and this photograph is the best capture of that moment.

Best fly

Stylogaster neglecta, a species of thickheaded fly

From Overlooked, needle-bellied, thick-headed fly (Aug 14).  One of my first good “black background” shots.  The white tip of the abdomen compliments the white flower stamens against the background.

Best “true” bug

Beameria venosa, a prairie obligate cicada

From North America’s smallest cicada (Aug 4).  So many different shades of green with white frosting on the bug’s body.  I tried taking this shot in portrait and it just didn’t work—I liked this landscape shot much better.

Best predator

Promachus hinei (Hines giant robber fly) & Ceratina sp. (small carpenter bee) prey

From Prey bee mine (Sept 14).  Robber flies are immensely photogenic, especially those in the genus Promachus due to their prominent “beards.”

Best camoflauge

Dicerca obscura on bark of dead persimmon

From The “obscure” Dicerca (June 19).  Sparkling and gaudy as specimens in a cabinet, the coloration of many jewel beetles actually helps them blend almost perfectly with the bark of their preferred tree hosts.

Best immature insect

Tetracha floridana (Florida metallic tiger beetle) 3rd-instar larva

From Anatomy of a Tiger Beetle Larva (Oct 22).  “Otherwordly” is invariably the first word that comes to mind when someone sees a tiger beetle larva for the first time.  I was lucky enough to get this one in profile with a nice view of its abdominal hump and its curious hooks.

Best arachnid

Centruroides vittatus (striped bark scorpion)

From A face only a mother could love (Oct 6).  Despite some minor depth-of-field problems with this photograph, I’m fascinated by its “smile.”

Best reptile

Eastern collared lizard (Crotaphytus collaris collaris) adult male

From North America’s most beautiful lizard (July 10).  A simply spectacular lizard—all I had to do was frame it well and get the flash right.

Best wildflower

Spiranthes magnicamporum (Great Plains ladies

From Great Plains Ladies’-tresses (Dec 7).  Few flowers are as photogenic as orchids, even native terrestrials with minute flowers such as this one.  I like the frosty texture of the lip and the starkness of the white flower on the black background.

Best natural history moment

Thermoregulatory behavior by Ellipsoptera hirtilabris (moustached tiger beetle)

From Tiger Beetles Agree—It’s Hot in Florida! (Dec 18). I chose this photo for the classic “stilting” and “sun-facing” thermoregulatory behaviors exhibited by this tiger beetle on a blistering hot day in Florida.

Best closeup

Megaphasma denticrus (giant walkingstick)

From North America’s longest insect (Aug 21).  I haven’t tried a whole lot of super close-up photographs yet.  I liked the combination of blue and brown colors on the black background.

Best Landscape

Sand Harbor Overlook, Lake Tahoe, Nevada

From Sand Harbor Overlook, Nevada (March 23).   My choice for “best landscape” again comes from Lake Tahoe.  This is not a great photo technically—I was still using a point-and-shoot and had to deal with foreground sun.  However, none of the other photos I took during my March visit to the area captivate me like this one.  I like the mix of colors with the silhouetted appearance of the trees on the point.
