Caterpillars Second submission, once again from Hickory, NC. These caterpillars were all over town a week ago, but now they seem to either died or cocooned. Please identify and provide some background. Thanks!

Hi Gene,
The website Caterpillars of Eastern Forests has a photo which identifies your caterpillar as an Orange-striped Oakworm (Anisota senatoria). The site says it is: “Charcoal black with orange-yellow stripes that fade appreciably in prepupal individuals. Head black. Second thoracic segment with long, black spinulose horns. Abdominal spines relatively small. Gregarious in early instars, then solitary. Occasionally reaches outbreak densities. One related species occurs in southern Ontario, and another in Florida and Georgia. Food: oaks and chestnuts. Caterpillar: August to October; 1 generation.” The adult moth is a pretty orange color.
