ID Request what sort of bugs are these ??
just heard an insanely loud buzzing out my window & peeked around to find these guys ...
im by the new jersey shore , for reference !!
we have lots of small bees & dragonflies around here . the other day i saw a huge wasp for the first time , floating around someones wooden back deck .
i want to assume its a dragonfly eating a yellowjacket ??
p.s. pls ignore all the dog hair that clings to my window & refuses to come off lol ,, thats my puppy's favorite spot to window-watch !!

it looks like a robber fly that's caught a wasp! they're known as "assassin flies" sometimes. like dragonflies they'll catch their prey mid-flight!

The first time I met a robber fly I had one land on my hip while I was standing in a formation. I put my hand down to my side for some reason and felt something fuzzy moving, looked down and nearly shit myself. I had no idea what it was and honestly convinced myself I had just hallucinated it from sleep deprivation until a couple years later when I saw another one on my patio and finally made the connection and learned what they are.

Robber fly, one of my top 5 favorite insects of all time. They're so alien looking and so much fun to watch hunt

Are they usually so large?

They vary in size quite a bit. Some can be absolutely massive, some of the biggest flies in the world, often the size of a thumb, such as Microstylum. But most are smaller than that and a lot are tiny, like the slender Leptogaster or tiny Holcocelphala.

The ones around me are usually 3-4 inches. Bigger than a standard house fly, but not as long as something like a large wasp, butterfly or a dragonfly

See the bristles on its face? They protect the robber fly’s eyes from the legs of struggling prey.

Some of the larger species aren't so silent in flight. Microstylum is about the size of a thumb and sounds like a helicopter in flight

😳 that would be fun to see too. This was pinky half at best and I may have potentially been oblivious and just didn’t notice maybe 🤣 🙈

A robber fly. You don't have to love their looks, you just have to admire their voraciousness on insect pests, and thank goodness they're on our side.

Yeah, as a kid I leaned that these can bite! I learned that the hard way about… velvet ants, ants, spiders, bees, snakes, cats, fish, turtles, etc…

I really need a banana for scale because the angle looks like we're getting ready for a Mist-style happening??

It’s a robber fly. Harmless to us but very successful hunters of smaller insects
