I’ve been rearing a group of around 50 Attacus atlas larvae in mostly closed plastic containers with a few air holes. They have been feeding on ligustrum lucidum and doing quite well, except for the fact that almost 40% failed to shed their skins into the second instar. Their head capsules pop off, and that’s pretty much it. They sit in their old skins for a day then die (presumably) due to exhaustion. I understand low moisture can be an issue with this, but they’ve been consistently kept at 80%+ humidity. Does anyone have experience with this happening with other saturniidae?
Thanks in advance.
Maybe humidity is too high. The skin softebes and sticks on them like glue they cannit take it off. I had that oroblems too so I only sprayed gently the footplant and put them on it than I waited 30 Minutes and put them into the box again. Which temerature do you keep them? I got to to 23 Celsius Rom Temerature but some of mine seem to be weak and they fall off the footplants so I widened the Air holes. I keep mine on several ligustrum species but the only like ovalifolium. I would be very pleased for ideas too because I lost 6 now. I dont know why.
Thanks for your response, Carmen. I’m also keeping them at relatively lower temperatures around 20-23 C, so that may be a partial factor in this problem.
Yes maybe. We have to find ourt which region they are from to find out the climate issues there maybe they need it warmer.
