I have not bred any T's of any kind. That being said, I have collected and observed MANY specimines of wild spider, mostly Tegenaria sp. Most of the females were already mated when collected. Many of these spiders would lay multiple eggsacs over a period of time. I noticed that most eggsacs were produced shortly after consuming a larger than normal meal. Because of this I tend to support the theory that the female eating the male is a way to ensure procreation of the species.
If I were to breed any T's, I would feed the mated female a few large meals and disturb her as little as possible.
