Saw it once last year 2007 trapped between the screen door. Finally released it. Uncommon to rare in the Twin Cities. Very obvious - look like the head and arms of a mantis fused onto the abdomen and wings of a fly. Small in size, about 1/2 inches or less. The book, Audubon Society Field Guide To North American Insects & Spiders second printing said the common name is Brown Mantidfly.

Found this bug on our patio in Ottawa, Canada in June, 2011. Was very sluggish. I'd never seen one before.
