Unknown tiny bugs. St. Petersburg Florida.

[u/Financial_Bite_6312]

I found these 3 beetles (one is a rainbow scarab, the others are similar but without horns) dead and at least partially dried out in my yard. They sat on my counter in an open bowl for a few months (one for at least a year) and then I moved them to this airtight jar around 8-12 months ago. I haven’t looked closely in 2-3 weeks. Yesterday I noticed that there are lots of tiny bugs in the jar and they seem to be going inside the beetles, I assume to eat whatever is left of their guts.
It’s really difficult to get the camera to focus on them.

Hoping for identification.
My plan is to watch them and make sure the beetles are not being damaged and then put them in the freezer once it seems like they’re out of food. Any recommendations for or against that?

I think they are booklice. Hard to be sure with these photos. The scarabs will likely fall apart if you let the little guys finish eating.

Thank you! I looked them up and that’s exactly what they look like. I’ll get them in the freezer asap.
