Cumberland Forest. Another wasp mimic, just like the previous photo. In fact, this species is in the same Genus, Spilomyia. Many hover flies are superb wasp mimics, pretending to be yellowjackets, paper wasps (as here), bald-faced hornets, ichneumonids, etc. As mentioned in the previous photo, you can tell these are flies, not wasps, by the eyes and the antennae, and lack of a "wasp waist".
