What's this Bug?

They are swarming every night at sunset for about the last week or so

Edit: thanks

I'm not sure what this is, but my guess was a Dobson fly.

Found on a trail in California, SF Bay Area. About an inch long.

It's a bit hard to make out in the photo, but there the center is a larger black insect being swarmed by dozens of small light brown ones. The larger one looks like some sort of beetle. What are the smaller ones?

Partial thumb for scale

I'm in Michigan if that helps. Never even known anyone around here who has seen or had a roach problem.

Terrible picture but it's the best i could get.

In the US south jersey.

They're tiny, dark with some spots and seem to like hanging out in windowsills.

They super squishy when squeezed and slow, they started appearing inside when the weather was getting warm a few weeks ago.

That's the closest species I found but it's said on wikipedia that it can be found in central/north America. I found it inside my house (not inhabited) in France.

And importantly, is it a harmful one that should be separated from my Ficus?

Small white spherical eggs, with small orange/brown dots, are laid in straight lines on a cactus spine

My first inclination is a recluse, but I'm aware of how many people get that wrong what with all the similar looking spiders around here.

I've been finding these around my house lately. Wondering what they are. I live in central New Jersey

Body (no legs): 2,5 - 3cm Location: Southwestern Germany

The web it built is huge. I would say 30-40cm in diameter, beautiful, round and even.

Central Connecticut.

Those photos were taken under extreme magnification and bright light - the actual size is about the size of an uncooked grain of rice. Maybe smaller. This one was killed by freezing to preserve its form.

In the last few days I've started to see a lot of these - I can find one crawling across my desk every 5 or 10 minutes if I remember to look (Though I can't find where they're coming from at all). They don't move all that fast - they're frankly pretty easy to capture or squash.

In person I don't think they look very much like ants but in the closeup I think they kind of do. Also hoping they aren't termites.

Thanks for any help.

Edit: Here's a video of one scurrying across my desk too: https://imgur.com/a/ZC15gNZ

There was quite a bit of these bees flying around while I was picking raspberries. They didn’t seem aggressive because they just ignored me and flew away there were even some that just flew pass me.

Found this guy under my grill cover. Curious what kind of spider it is.
