My setup

Here is a picture of my plastic cabinet for the mealworms.  I put the worms in the bottom drawer and am picking out the pupae to put in the middle drawer.  I don't know if I really have to separate them, but read somewhere that the worms will eventually eat the pupae, and the beetles will eat the eggs.  For now, I'll separate them since I don't have many and it's easy.  I guess the novelty will wear off after a while!
