No special treatment was given to either the male or the female prior to introduction. Both were fed a few days prior.

1st pairing occurred 4/25/10. Male was placed inside female's enclosure. Once the male found the female's webbing, he began drumming. She responded by drumming heavily almost immediately. She approached him and mating soon followed. Several insertions were witnessed and the two remained paired for about 5 minutes before the male withdrew. He was left with the female to co-hab. He was found consumed a week later.

Female was kept in our spider room (temp 72-75, humidity 60%) and fed weekly (1 sub adult or adult dubia OR 4-6 large crickets). She was also misted weekly.

Female refused food 7/27/10. Begins webbing herself in.

Sac was produced 7/30/10. She did not accept food while holding the sac, but I continued to mist her once weekly as she did not attempt to go near her water dish either. I did witness her leave the sac to drink water from her web after misting.

Sac was pulled 9/26/10. We found 60 post embryos darkening for 2nd instar molt. 2 eggs were black (bad).

Babies molted to 2nd instar 10/7/10-10/8/10. Final count 58. 2 post embryos died before molting.

Females last molt
August of 2012

Began pairing her with a small (3.5" max) loaned male on 12/19/12
2 other pairing sessions took place throughout December, however only 1 had action

Around January 20th of 2013 the female began prepping her enclosure for a sack. No special care was provided up until that point.
January 27th of 2013 i flooded her enclosure and upped the heat.
January 29th of 2013 she made a sack.

I left the sack with the mom until February 28th of 2013. During the time the mom was with the sack I continued to saturate/flood the back half of her enclosures substrate via vent holes about once weekly the whole duration. I made sure water was never anywhere near the sack. I also kept a heat lamp about 6-8" away from the enclosure the whole 30 days, both during the day and at night.

When i pulled the sack they were already 1i (maybe an ewl or two in mid molt) and the total count was 97. Ive separated them up already into condiment cups, and noticed that 3 of them are already eating sackmates, bringing the total count to 94 at this point.
