Mystery Moth
Dear Bugman,
Love your site! My boys and I are having so much fun identifying the different critters we come across in our yard. This unfortunate creature was removed from the grill of our car. We don’t come across too many moths this size in our area, so at first I thought it could be some sort of sphinx, I’m not sure that’s right though. We live in a heavily wooded area in southwest WA. What is it? Thanks,
Heidi

Hi Heidi,
Some specimens of Catocala relicta have nearly white forewings, giving rise to the common name White Underwing. Your specimen has gray forewings, which makes the common name White Underwing seem odd. BugGuide shows specimens with a wide range of forewing tonalities.
