Jan, they go through a period of diapause at the beginning (well more a sort of delay before anything starts happening) for up to 3 months and then development is about 3 months. So generally 3-6 months in the egg.
CherryBrandy, I can't remember total egg numbers but let's just say around 18, with 13 hatching from at least 5 females.
Thanks Ozric
