Underwing Moth

Underwing Moth

Dear BeeJay,
While this Underwing Moth in the genus Catocala stands out against the painted blue wall, if it had landed on a tree trunk, it would be nearly invisible like this Walnut Underwing on a carob tree at our Mount Washington, Los Angeles office.  The camouflage you mentioned is even more pronounced if you consider the coloration of the moth’s underwings, which are often brightly colored like this Underwing.  When the moth is startled and takes flight, the bright colors are quite noticeable, and a predator, like a bird, would be searching for those colors and overlook the Underwing once it lands again on a matching trunk.
