With just 10 beetles, it will be a while before you get good production. If you are intending to breed mealworms, I would suggest starting with a LOT more worms to get more pupae to get more beetles...aka, more baby mealworms.
When not provided adaquet moisture source, I guess it is possible that the mealworms may eat pupae, but don't think it be anything to worry about. I do like to seperate the pupae, which is typically found on the surface of the substrate, and place into holding containers. Daily I check the container to see if any have emerged as beetles and transfer them into the beetle container, which is set-up the same as the mealworm container.
The benefit of seperating the beetles from the mealworms is that you can keep containers of various sizes. Each month I move beetles into a new container. But if you don't mind fishing for a size you need later on, you can keep everyone in the same container. It is just a matter of convience in the future...
Mealworm beetles are darkling beetles. The eggs they lay are tiny tiny tiny. They are sticky and are quickly coated with particles. I doubt they intentionally eat the eggs since it will be a like a speck of dust.
I have a website with information about mealworms (aka darkling beetles) if you want to know more about their life cycle. Breeding them is very easy. But, as I mentioned before, if you want more baby worms, get more beetles.
