Caterpillar found by oak tree
May 30, 2010
The of this caterpillar I took when I found it on my drivway which has large oaks on either side of it. I can not find its piture in any of my insect books.
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.
