I guess the "80-104 F" recommendation isn't a joke. I thought mine would be okay at 75-80 degrees without a direct light on them. I now measured a certain spot in my project room where it's 54% humidity, and 93 F degrees, and I moved my last remaining mantid to it under a 100 W Halogen lamp. I also spray it lightly daily just to make sure there are SOME water droplets in case he wants to drink or needs the moisture to molt.
