I culture my own fruit flies. I am raising 500 crickets to try and breed them. They are about a week away from laying eggs I think, so I'll see how that goes. I bought 500 meal worms last week to try and breed them, I'm already getting pupa so that's a good sign. If I can ever get my hands on a bean weevil culture I will culture them too. I think I'm going to try red wigglers next, I think my frogs would enjoy them.
