Advertisement Hi everyone, I am aware there are other threads similar to this but they didn’t answer my questions. I have latrodectus Hesperus and hasselti that I want to breed. They are related to each other though. I’ve heard conflicting information on whether this can cause issues or not though. Anyway, I want to know how to introduce the males to the females, how long it takes for them to mate once being introduced and if there are any ways to know if the spiders are mature. I tried to introduce the male and the female yesterday and the female had a feeding response. The males are almost as big as the female species legspan wise but the females have their adult coloration pretty much and are adult sized. The hasselti males are still in their webs and are smaller.
