Nightshift Visitor

During the night shift at my work, lots of crazy things fly in. Big things. I don't think a bat has flown in yet, but I'm sure that could happen.
One night last week a moth flew in and didn't move until noon the next day. He parked himself on one of the cutters, and didn't move until he was poked too many times (he didn't move so people thought maybe it was dead).
I took a picture and put a ruler up next to it so as to show the size of this thing.
