Imperial Moth Caterpillar

Dear Don,
This impressive caterpillar is an Imperial Moth Caterpillar and its orange color indicates it is pre-pupal.  It has recently come down from the deciduous or coniferous tree upon which it was feeding.  According to BugGuide:  “Larvae feed on leaves of Bald Cypress, basswood, birch, cedar, elm, hickory, Honeylocust, maple, oak, pine, Sassafras (
Sassafras albidum), Sweetgum (Liquidambar styraciflua), sycamore, walnut.  Adults do not feed.”
