Salmonsaladsandwich,
Curtain is up, cold and hot floor returns are covered with organza, and I thought I had it all fixed---I didn't think about the light bulbs! The room has a couple of hot, recessed ceiling lights, three wall bullets (with CFLs) lighting the mantids and two heat lamps. So far, they haven't gotten anywhere near the ceiling, I think the CFLs in the wall are barely warm (I'll verify tomorrow) and thank you very much for the head's up---I shall turn off the heat lamps when the boys are out!
Krissim Klaw,
The room is now totally contained. I have several large plants and a tall group of curvy willow branches in the bug room (and I had a terrible time finding the Budwing after I left for a few minutes to answer the phone!) Not doing that again. Both the ghost and Budwing can disappear in the branches! So far neither has gotten to the big window but it has a five foot tall number 12 covering it, designed in bright blue and green LED lights (signifying this household as a Seattle Seahawks 12th man fan.) It is so bright, it might be a deterrent, or at least give them something to land on.
And, to her dismay, the dog is now shut out of the bug room when the mantids are being fed. Cats can't get in and now with the big curtain in place, the mantids can't get out Unless some other danger is pointed out to me, I think the room is secure and mantid-friendly.
I am assuming you only let one boy fly free at a time, right? And, your comment about the boys flying at night---now I get why my Chinese male seemed so agitated at night. So, in the wild, they are kind of like moths?
Thanks to both of you for your thoughts and suggestions. Very appreciated.
