Similar thing happend last year... My mantis eggcases hatched on me, and I waited a shed, and seperated all 75of them into large plastic cups, with a large square of mesh elasticed on top... somehow, 4 escaped, and got into an already 2nd shed one, and all four were eaten... It was still a mystery how they got out. No others went out, and they all went into that one cage somehow... It was wierd seeing four mantis cages empty, and one with a super fat mantis, adn four half eaten bug bodies... But that wasn't near as bad as this sounds. That REALLY blows, adn I have some idea of how you are feeling. Hope your friend understands!
