Woke up this morning and had these all over my back walkway! Granted, we've been having LOTS of rain in NJ but we've never had these before! The adult looks like a bee but no wings and stays on the ground. The wiggly larvae(?) are all over and sometimes I spy what I think is an adult (see pics). I poured apple cider vinegar on them but now they're in the pond. Unfortunately we don't have fish anymore, it's just a water feature. What is causing them and how do I safely get rid of them without poisoning anything? 😢

The top picture looks like a lot of maggots, fly larvae. I can't make out the other pictures, other than that there is some black and white thing in them. Is there any way you can get a sharper picture of it (and the other thing with the maggots)?

Here are more shots, sooby. Hope they help.

Very interesting

Cause: most likely all the rain , it often washes out insect nest areas.
To bad you don't have enough hungry birds, they look tasty

From the photos they look like
Necolytus caprea
Banded ash borer
But they would be in a dead tree or something and seems like too many for one spot.

At my house I would leave them over night and something would come to eat them

But if I wanted to kill them I often use cooking oil spray (like pam) all soft body insects breath through the body and oil suffocates them.

Not an expert in anything just personal experience

Good luck

If that's a banded ash borer, which looks like this

those are not its larvae as far as I can make out from the pictures. I'm pretty sure they are fly larvae.

Is there any way you can get one of those black and white things onto white printer paper so that the camera/phone can focus better on them?
