I have a bunch of these dudes flying around my front door. Over the last week it has gotten worse. I'm in MA for reference. They flit around like flies, we have honey bees on our property and they don't fly like a bee if that makes sense. They are building what looks like ant hills around our front walkway and are starting to get annoying walking in and out. Looked up on some flying bug charts and nothing seems to match. I took some better pics today and hadn't noticed the green eyes, but they are prominent.
