Darkling Beetles

[ThatOneInvertNoob]

Hi! So, for a bit of background, I’ve recently started a mealworm colony to cut down on feeder costs. I’ve got a couple beetles now, but I don’t know how to tell if they’re dead. xD
Do their legs curl against their bodies, or is there something else I need to be looking for so I can get out dead ones sooner rather than later?

If they look dead and they haven’t moved in a really long time it’s probably dead
