I’m looking for the identity of these caterpillars. They were feeding on a blueberry bush. They fed in bunches at the end of a branch and raised their head and tail when disturbed. Seen in mid- August.
The defensive posture you have described and photographed is consistent with the Prominent Caterpillars in the genus Datana, and the food plant and the coloration indicate that your specimens are Drexel’s Datana, Datana drexelii, which is described on BugGuide.
Thank you!! I’ve been trying to find out what tese are ever since I first saw them! I really appreciate your help.
