|Less than 1/4 inch long, resting on my wall under a lamp.|
So small, and yet so smart! As soon as I approached with the camera, he started to run; two shots, and he scooted down a crack and disappeared. I waited, but he never showed his face again.
I'll send his photo in to BugGuide.
And he's already identified; that was quick! A Diamondback moth, Plutella xylostella. Thanks, Steve!
