I hatched some praying mantises about a week ago (a Chinese mantis Ootheca and a Carolina mantis Ootheca) and I kept 5 of each species, but then after a couple days, they just dropped dead and now I only have 1, which will probably die soon too. Does this normally happen or am I doing something wrong? I put them in a 32 oz cup with a vented lid and I put in a lodicule stick and other cleansed sticks and twigs. I also misted them with distilled water every day because I live in a dryer climate. A few of them I think tried to molt just fell and stopped moving.
