Today is the first day I decided to add the meal-worms to my mantids diets. Only the pet shop only had the 1 1/2" size. So I cut the head off and my little dudes went to town on them. I noticed the little fatty fats getting a bit too fat. To the point where my Giant Asians red and black weird lines under the abdomen or what ever are like so exposed it almost looks like they are going to pop! So far they are in tact but I remember a member trying an experiment a while ago where he put this theory of overeating to the test. He took pics of the little mantid with his guts or whatever green ooze hanging out. So, my nephews ask do they know when to stop eating, Auntie?? I go , I hope so or else, Squuush!! Anyway, they are just really plump and sweaty like. They ate the entire worm so I don't think they knew to stop and would have kept on going if the worms had been any bigger. Maybe next time I'll have to cut t in half!! Just to be safe!!!
