Finally got one as a baby(3/4"). Started as brown, but has colored up beautifully. Found a home and walled it up with carefully placed stones so that (Isuppose) it can have a secure place. Takes out one stone so that it can come out to feed. When done, it replaces the stone. For the last 5 days, it has not removed the stone to expose itsself. I finally shook the house and dislodged some stones to see if perhaps it died. Still alive. In a couple minutes, it rebuilt the wall.QUESTION...why has it not come out the last few days? OR... is it only coming out at night?? I am sort of keeping a log on it's doings and find it the most interesting creature I have come across. The wall it has built is not haphazard, but a wall of carefully sized stones, apparently cemented together by some sort of secretion. Has anyone else had a mantis do this?Thanks.
