I've only ever seen that once, strangely enough it was my "blind" (no compound eyes) mantid with two crickets in each arm, but one escaped cos he only had it by the back leg.
Mantis wisper, nice pic, they all do that, if you are lucky enough to catch them doing it.I had a tiny new nymph do it yesterday, so funny, baby nymph, big ffs in both hands. I swear, sometimes they act like it's their last meal and so greedy, have u ever seen em grab the food then turn away from whoever is near? That is so cute, or when u see them get it and they go get in their favorite posistion to eat it, savoring the moment! :lol:
