Thank you very much. I think we will hold off until another molt anyway. Maybe in a year or so I'll be more prepared to deal with a bunch of slings.That's a great pic of a moult, everything you need to see clearly displayed - the spermatheca and the uterus externus. However, it looks sub-adult to me as it doesnt look sclerotised spermatheca. Its possible to use this your female for 2 reasons:
1. sub-adult females are not uncommonly used for breeding
2. the moult is obviously the discarded organs of a previous stage of maturity.
