Was thinking a Dung Fly?
On Field Horsetail, but I think I flushed it there.
On cup plant, but not showing any behavior.
On witch hazel.
Kept its wings apart at rest that I could see.
Not sure if its a Sand wasp or Cuckoo bee.
This fly was infested by a fungus. The brown fuzzy parts at the joints.
Growing in compost/woodchips.
On a rain barrel, in a meadow/forest.
These guys are very odd to me. They have very long hanging legs (compared to hover flies) and they seem to have long mouthpieces? Not like most flies I know.
