I discovered this interesting caterpillar while doing yard work last summer. It was on a smilax plant (also called a greenbrier). I love the tendril-like projections on the curve-lined owlet (Phyprosopus callitrichoides). The neatest part is when they hold on with their anterior prolegs and dangle like a dead leaf.
