I used to raise bean beetles, they're easy and a lot of fun, the only thing I didn't like about them was the boom/bust cycle. I never quite figured out how to get them to overlap. You'd set up a colony and have 1000's of beetles in about a month, but then two weeks later you had none. The adults are non-feeding, they're only job is to breed and lay eggs and then die in a week or so. They do make a great supplemental feeder though and one of these days I'd like to pick up another colony.
