In and outside our house (inside one, outside more of them)

This is a small one. Also found one about an inch long.

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
