Quck answer
Male Brown Widows are not bothered by the fact that female spiders mate and then kill their partners. In fact, they seem to prefer it. This behavior, known as sexual cannibalism, may actually benefit male widows by increasing their chances of fathering offspring. Researchers have found that males are more likely to approach and mate with females that have already eaten a mate than those who have not. This may be because the female is less likely to attack a male after she has already eaten one. Overall, sexual cannibalism is a natural and accepted behavior among Brown Widows.
Wild Animals
Male brown widow spiders are willing to risk being eaten after mating with an older female. According to new research, these spiders go through an elaborate courtship ritual, even though there’s a good chance they’ll be cannibalized. The study, published in the journal Animal Behaviour in March 2018, found that brown widow males actually prefer mating with older females, despite their low chances of survival. The research team introduced virgin brown widow males to females of different ages and found that the males spent significantly more time courting the older females than the younger ones. The team believes that this may be due to female pheromones, as older females may give off a more enticing scent to trick males into thinking they’re more fertile.
FAQ
1. What is the brown widow spider?
The brown widow spider is a venomous spider found in many parts of the world, including the United States, South Africa, and Australia. It is closely related to the more well-known black widow spider, but is typically smaller and lighter in color.
2. How do brown widow spiders mate?
Brown widow spiders engage in a unique mating behavior known as “sexual cannibalism.” The male spider will approach the female and offer her a gift of food. If she accepts the gift, the male will then mate with her. However, in many cases, the female will simply eat the male after he offers her the gift.
3. Why do male brown widows accept the risk of mating?
Despite the risk of being eaten, male brown widows continue to engage in this behavior because it increases their chances of reproducing. By offering the female a gift, the male is able to demonstrate his fitness as a potential mate, and may be more likely to successfully mate and pass on his genes.
4. How does sexual cannibalism benefit female brown widows?
Female brown widows benefit from sexual cannibalism because it provides them with a valuable source of nutrition.

Additionally, by consuming the male, the female may be able to avoid mating with a lower-quality mate in the future.
5. What are the risks of sexual cannibalism for female brown widows?
While sexual cannibalism can provide important benefits for female brown widows, there are also risks involved. If the female consumes the male before mating, she may miss out on the opportunity to reproduce. Additionally, if the male is not providing enough food, the female may not be able to fully nourish herself or her offspring.
6. Do all brown widow spiders engage in sexual cannibalism?
No, not all brown widow spiders engage in sexual cannibalism. This behavior is more common in certain populations and may be influenced by factors such as environmental conditions and the availability of food.
