I started off my colony with 100 mealworms. Most of them have been fed off to my leo, Chibi, but a few have become pupa and a couple of beetles. From 100 mealworms I now have, 4 beetles and 10 pupa. My colony is on its way to producing me some wormies.
Does anyone know how to tell the difference between male and female beetles? I have four and there are two that are bigger than the other two. And when can I expect them to start producing babies once they become black? (two are still brown).
