Mine is supposed to be an active guy, but sticks to the entrance to his cave 99.9% of the time (G. smithii). I've got a nano for him to go into soon, though, so at least I'll see more of him than I currently do in a 55 refugium.
FlyGTI, what species do you have? Ball in Oskaloosa has a nice peacock I got to see last week, but other than that wasn't aware of anyone else around central Iowa that kept mantis...
