Identification
Later instar caterpillars densely covered in yellowish, reddish, brown, or mouse gray setae (hairs). Middorsal crest has rusty to smoky setae. “Tail” setae extend well beyond the body.
Feeding Habits
Puss caterpillars skeletonize many species of deciduous trees such as oaks, elms, birch, cherry, hackberry, persimmon, poplar, sassafras, wax myrtle, and more.
Medical Significance
All larval instars, as well as exuviae (cast skins), have venomous spines that may produce a painful sting. Sensitive individuals who develop systemic symptoms are urged to seek immediate medical attention.
