I found both adult females in the same location, their thin sheet webs approximately 6 inches apart, which seemed odd because all of them, including the male I captured earlier from their web, seemed more aggressive then the usual true spider.

I decided to house them together, with both their egg sacs. Just as in the wild the more dominant, larger female took the high ground, and the smaller made a web and kept her egg sac below. You can see the blurry, smaller spiders egg sac, on the left side of the image.

Approximately a few hours after the larger egg sac hatched, both mothers died within minutes of each other while I had them outside taking these photos. I did not see either of them bite each other, and did not see a spiderling biting either; although either is possible as I was focused on shooting the hatchlings with my eye in my camera.
