These caterpillars have been eating the leaves of my rose glow barberry bush since August. Unfortunately I only just noticed this the past week. (The reason I knew approximately when is because I had taken a photo of a monarch pupa in mid July when these bushes were full of leaves.) I've had these bushes for four years and this has never happened before. I have not seen these caterpillars anywhere else on our acre plus lot. They hang by a web like a spider's web.
