However, even this species is rare and not considered a significant threat to humans. **

Female black widows eat their mates for several reasons. One reason is that it provides the female with a valuable source of nutrients, which can be especially important for her if food is scarce. Additionally, consuming the male after mating ensures that he will not mate with any other females, increasing the chances of the female's offspring surviving. This behavior may also be a way for the female to gain additional energy for producing and caring for her eggs. Overall, this behavior has likely evolved as a way for the female to increase her own reproductive success. **

This is why you may only see a spark when the gas heater is turned on, and not a continuous flame. **
