Hello its Austin and I wanted to know how come every time I raise my Polyphemus, Cecropia or Luna moth larvae, half of them always die. I mean I am hatching them from eggs, and they seem to do fine until they start to reach there 5th instar. The fist day they look fine , but the next day they are all black and drained of there body fluids. Am I doing something wrong? I always keep them in a laundry basket( the one with a clear screen and an open top). I feed them by cutting tree limbs off, cleaning the leaves and sticking them in a clean soda bottle, so they wont drown and die. But seemingly that dose not work so I have to be doing something wrong. HELP!!!!!!!!!!!!!!!!1
