Regarding the Egyptian drill, as someone pointed out in the comments, archaeologists really need a working knowledge of modern hand tools and their usage, because the designs have not changed that much over the millennia. There's only so many ways for them to work after all.

Jack Shepherd is one of the people I keep in mind in case I need to put together a time-travelling commando unit.

You had me at cockroaches eating each others' wings - predictable!

It reminds me of something I've observed with ant queens. Ant queens start out with wings, but after they have mated and it's time to run around and dig a new nest, they drop to the ground and tear their wings off. As that article on cockroaches speculate, this probably has to do with the wings becoming a liability at that point (making them more visible to predators, making it harder to dig).

But the interesting thing is that, in one of the species I study, sometimes queens don't lose their wings. That might be because they haven't mated as much as they'd prefer (they usually mate multiply because there are benefits to that), or sometimes they don't mate at all if the conditions are poor. Anyway, regardless of the reason, eventually the workers from the same nest will chew off the queen's wings for her.

...if nothing else, hopefully this is at least a distraction while you are processing other things!
