I have a large shelving unit with my uromastyx lizard on the bottom. Since those are a desert species they like it very hot. I am running two 150w mercury vapor lights on him. The heat rises to the mantids above. Problem is this time of year that the heat needs to be contained to keep the mantids much above 70. I have resorted to putting the ones that need the heat most directly above the lamps. I came up with a way to hold the heat in. I put insulated sheathing with a reflective film on both sides and the top of the shelf unit. Today I had a piece of plexi glass cut to fit the front. I just hung it from some hooks at the top so it is still easy to remove. My lowest temperature is about 83 while near the lamps it is 90. Still have to wait and see if the heat from the uros rocks and sand keep it warm for awhile at night or not. Crude but effective.
Here are a couple pics. The plexi is so clear that it is hard to see. Click to enlarge.
