Ilia Underwing Caterpillar

Dear Bill,
We do believe we matched your caterpillar to an Ilia Underwing, Catocala ilia, on Bugguide.  It too was found on Oak.  BugGuide indicates:  “very occasionally spectacular lichen mimics are encountered.”
Your caterpillar is one of the lichen mimics.  The species is also known as The Wife or The Beloved Underwing.

Dear Daniel, Thanks so much for your answer. I have never seen such perfect camouflage.
