They just don’t appear when I’m in the field. I want to come upon butterfly caterpillars, and I regret that I don’t have a treasure trove of images of this unique stage of butterfly metamorphosis. They remain in the shadows, or hidden from view, high up in trees, or unseen resting on the underside of ground hugging plants.
Those who have amassed field guides to butterfly caterpillars have earned my respect. Hard to do, for sure.
That explains my excitement when on September 27th I discovered a tree in Doak field, and on it were dozens of these chewing machines. Striking coloration, a pair of horn-like extensions just back of the heads, butterfly caterpillars? How could they not be? Which?
Checked my field guides for butterflies. No, no, no. These are moth caterpillars. Amazing critters they are, but . . . moth caterpillars. Back to square one, where, oh, where . . . why, oh why does my butterfly caterpillar cache not grow? ‘Tis not easy.
