I found this bug in my gym bag on 10/13/16. I found the bug on the University of Texas at Austin campus. The bug has a long black body divided into two parts. Half of the bottom of the back is transparent. I captured the bug (because it got into my room) and released it outside. The attached photos are the bug in a plastic case.

Dear TKR,
Because of the transparent part of the body you observed, the Black Soldier Fly,
Hermetia illucens, is sometimes called a Window Fly.  It is described on BugGuide as being:  “Large soldier fly, all black with bright white tarsi. Underneath, first abdominal segment has clear areas. Wings have purplish sheen. Likely a wasp mimic, it buzzes loudly.”  This is a harmless species that does not sting nor bite.  Because of your catch and release handling of this sighting, we are tagging the posting with the Bug Humanitarian Award.
