Underwing Moth

What is this?

At well over 5 megabytes, this is the largest photo with the shortest, most terse demand we have ever received. Three words with a questionmark in the subject heading isn’t our idea of a letter. This is an Underwing Moth in the genus Catocala. Moths in this genus often have brightly colored underwings and drab forewings that often blend into the patterns of tree bark. The idea is that when the moth is flying, the predator will hunt out the bright colors, but when the moth comes to rest, it seems to disappear.

  1. I’m sad to know that my visitor is not related to Godzilla, but happy to find out that it is an Underwing Caterpillar. I hope I recognize him/her when he gets his wings.
    Thank you.

  2. I found a Underwing moth on my deck this morning, Aug. 3rd 2017, Shoshone, Idaho.
    Didn’t know what it was, thanks to your website, I know now. Joann of Shoshone, Idaho.
