I have both blatta lateralis and dubias, they are both awesome! I hate crickets, and mealworms are not a very good staple for most reptiles as they have a higher shell to meat ratio. Most leo's also will not eat things that are dead and not moving around. They are quite the great little hunters

I found a site that sells a thousand turks for under 20 bucks. It's the cheapest I've found. Although now I breed Turks and Dubias, but it was good to start a colony with.
