The argid sawfly Sericoceros krugii wasn’t the only insect I saw associated with seagrape (Coccoloba uvifera) during my May trip to Puerto Rico. While exploring the magnificent coastal sand dune system near Isabela (northwestern Puerto Rico), I encountered a tree with literally dozens of frosty, … Continue reading →
