Found this little guy (gal?) inside. His body is light gray, shaped like a triangle with the head flat. He has two round wings, somewhat held above his body. They're fairly transparent with some faint striping or spotting... no veining that I can see. He's very active and keeps walking around, but I've not seen it fly. When I first saw him and nudged him, he jumped straight up and made a faint clicking sound. Thought he might be a moth fly, but he's got no "fur" and no noticeable antennae. I apologize for the bad pictures, but it was the best I could catch of this active little guy.
