Haha! What an amusing story! I think some reptiles are more intelligent than we give them credit for!!!
As for the little black bugs I think I was told at one time that they are deliberately placed with crickets to 'clean up'. I'm not sure if this is true or not, but if they get in with my girls they'll be gone. I have had a few of them mature, and they do fly. They look somewhat like small mealworm-beetles. Haven't been bit yet, but I tend to throw those buggers out when I find them!! =)
P.S. Why is the word 'credit' underlined?? I didn't do that!!! LOL
