Yellow Jacket preys upon Bot Fly

Dear Heather,
The prey in your image is a Rodent Bot Fly, and the predator appears to be a Yellowjacket, a close relative of Hornets.  Adult Yellowjackets prey upon various insects, especially caterpillars, to feed to larvae that are developing in the paper nest they build.
