Geographic location of the bug: Green Valley, AZ

Your letter to the bugman: Found three of these running and taking short flights around my house after unpacking a tv that a friend gave me. The item came from Vista, CA, and was stored in a garage here in GV for a couple of weeks. I caught all three (one at a time) and tossed them out onto my back patio and yard. Found one dead the next day, but no sign of the others. Sunday evening I was dumping trash into a large pickup container for collection the next morning and found this one dead in the bottom of an 18 x 18 x 24 deep plastic trash box. Have no idea where they came from or what they are or were.
