Haha - I always thought that the feeder crickets looked different from any others I'd seen around here. Now I know I'm not the only one.
I successfully keep small amounts of crickets in the same 32-ounce bug cups previously used for mantids before they outgrew them. With a chunk of cardboard egg carton and fresh romaine lettuce, they can live in there for weeks. Even the feeding hole in the side is useful for dispensing crickets one at a time, and if you dispense them into a shot glass that's the same size as the feeding hole, chances of escape are slim. The best part is that, once in the shot glass, they don't jump! In fact they barely move at all. I've been using this method for weeks now and I have yet to see a cricket jump out of the shot glass. This allows plenty of time (and both hands) to open the lid on the mantis container before it's bottoms up for the cricket. B)
