One should be careful what you swat. I bet your first impulse is that this is a scary wasp or hornet and a threat. That was mine too. But it is a Hoverfly mimicking a hornet.
Eastern Hornet Fly-Spilomyia longicornis.
I thought this was a wasp or hornet until noticing the antennae which are fly like…shorter than a Hymenoptera’s would be. A head on shot to truly appreciate those beautiful eyes would have been ice but wasn’t possible.
I was really happy this one decided to drop by while I was shooting something else. Thank you peripheral vision.
