Catocala relicta
Ogema, Price County, Wisconsin, USA
August 18, 2007
Size: About 1 1/4 inch
This moth was clinging to a screen without moving for two days. The first shot was as close as I could get to its back, as it was on the second floor of a hotel. I got a close view of its ventral side (second photo)through the screen. Can someone ID it?

White underwing moth?
I suspect this is a specimen of the white underwing moth, Catocala relicta, one of our most spectacular moths. The hind wings (hidden here as the moth is at rest) should be banded black and white. Normally, this insect rests on tree bark (like the trunk of a birch), where it is perfectly camouflaged. If it is discovered, it flashes those bold hindwings, startling the potential predator.

Yes, White Underwing
The forewing color varies somewhat; this one is very similar to the photo here.

Catocala relicta
Eric, there was a delay in posting the second (underside) image. Here it is. Does this support your ID?
