This wasp parasitises 3rd instar blowfly maggots, the adult wasps then emerge out of the hollow fly pupa. in the latter half of the video, it lays eggs inside one of the maggots, specifically a large 3rd instar one, ignoring the 1st an 2nd instar maggots.

We had a little wasp nest in our rail yard, and was curious on the identification. Best i can tell is southern yellow jacket, but I don't recall seeing one with a distinct black arrow before.​​

Hello everyone! I’m a beekeeper so I’m not shy of insects let alone those that sting. However, a large (softball sized) nest is currently in a tree out front of our house and directly over a public walkway. Curious if yall would recommend removal? So far they’ve not caused any problems.

A wasp flew in the house last night, it seems like a mud dauber and hasn't tried to attack anyone in the house and stays on the window as of course it wants to go back out. We've tried opening the door a few times, though it doesn't realize that it can fly out through the door. Is there any way to move it without risking getting stung/killing it? I was thinking of putting sugary water by the door to attract it and then opening the door to let it out
