Well she's destroyed EVERY molt since I bought her as like a .25in sling lol.
She turns them into wall decorations on her web, also shes made her web inside this very large open corkbark I gave her, so even if she hasn't destroyed them all they're where I cant get to.
@Pyrelitha Yes, it is often very difficult to sex them using their exuvia. My advice is to give it a try anyway. The spot you need to see is very small and might very well be intact enough to see spermathecae. I have been able to find it using a tiny bit of torn up exuvia. It will be more difficult if they are male, but if there is spermathecae you might still be able to find it.
My girl is a moult shredder as well, this species is a pain to vent sex, I kept going back and forth between male and female until she was in heavy pre-moult at around 3.5" when she looked fairly obviously female, I ended up pulling the moult just minutes after she was free of it to confirm.
