Bill's Botanical Forays

Today, while looking at a Black Oak (Quercus velutina) specimen, I spotted a green fuzzy object moving around on a leaf. It was a Crown Slug Caterpillar (Isa textula) It is a fairly common moth in Eastern North America and its larva can be found on Cherry, Maple, Oak, Basswood, and Elm species. In the adult stage, this creature is a nondescript brown moth.
