Hello all,
A lot of my Antheraea yamamai larvae fail to shed their fourth skin. They end up being stuck in it. It often seem to be holding very strongly around the breathing spiracles.
Sometimes they get out partially and the old skin is in pieces still around their body, glued to their body at the spiracles.
Sometimes i can help them out by peeling off the old skin with tweezers, but it is hard to get all the bits off without damageing the new skin.
Sometimes it’s just impossible to get it off.
Does anyone know what might cause this? Too hot? Too cold? Too humid? Too dry?
Or does any of you have the same issue happening with any of their larvae?
I had exactly the same issue happening with them last year.
