When I came home from the last night of conferences she was finishing laying her egg sac, which is called an ootheca. If, big if, she was involved with a mantis prior to being caught these may be fertilized eggs. If so, they will hatch in 24 to 48 days. There could be hundreds of them. Unless they separate them, they will eat each other until one remains. Hmm, kind of like "Survivor."
Everything we read said she would die shortly after laying the eggs. However, as the post started out, she lives on. I think that because she is in a warm climate with food and water she might last a little longer than normal. It will be interesting to see. We have been forgetting to go to the pet store, so I spent some time looking under the stepping stones in our yard with a fork in hand. I found a worm, which I wasn't sure if she would eat, but I rinsed it off and offered it to her. Snapped up and eaten within ten minutes. I also found a large creepy centipede. I was able to flip it onto it's back, scooped it up, and brought it in. I was very careful not to drop it because I do despise centipedes! Millie has gotten used to me lowering sacrificial offerings into her cage. She is not put out by the fork in the least. She was quite delighted with the crawly creature. It will be interesting to see how things progress; I will of course keep you posted!
