This appears to be S. angulatus. The best feature to separate this from the other eastern species, S. macer, is whether the propleuron (the swollen sclerite on the anterior edge of the thorax) is yellow (S. macer) or black with silvery hairs (S. angulatus). It looks silvery here.

Moved from Systropus.

count the wings...these are flies. Syrphid or Soldier Flies maybe? I'm not good enough with flies to ID just on overall appearance so you'll have to wait for someone that has more experience with them.

definitely not a Syrphid, but the antennae are right for a Stratiomyid.

Believe it or not, these are a mating pair of Systropus, which are bee flies in the family Bombyliidae. Great find!

Bee flies, huh...
I would have never thought of these being bee flies!
