I paired her with 3 wild caught freshly molted mature males
From 13/3/14 to 15/5/14 each male going in twice.
Sack layed 19/6/14
Pulled sack 27/7/14 (38 days)all EWL and no infertile eggs
Started molting to n2 a few weeks later
Over the next month they steadily got darker(lost 3 or 4)
After 97 days from the sack being layed they started molting to slings.
I lost 14 during this molt stage due to bad molts.
Total spiderlings 104
