Two reports describe how male black widow spiders adjust their mating strategies to cope with the high risks and competition involved in finding a mate. During courtship, males modify the web environment around a female by cutting and gathering silk using their own silk threads. This action helps discourage other potential suitors from approaching the female. In addition, males appear to reduce the time and effort needed to locate receptive females by using cues left behind by other males. The accounts say males “hitchhike” on silk threads laid on the female’s web by competitors, allowing them to reach the female more quickly than they would on their own. Together, the studies present a picture of coordinated and opportunistic behavior: males actively reshape the female’s web to limit rival access while also taking advantage of existing silk signals produced by other males. Both approaches aim to improve mating chances in an environment where encounters are dangerous and multiple males may pursue the same mate.

- Male black widow males change their behavior during courtship to improve mating success.
- Males snip and bundle silk on the female’s web using their own silk.
- This silk modification helps discourage other male suitors from approaching.
- Males also locate mates more quickly by using silk threads left by other males.
- The reports describe these silk-based behaviors as responses to competition and mating risk.
Mating is risky business for black widow males—so they hitchhike on the silk threads left by competitors to more quickly find a mate. Christopher Intagliata reports. Learn more about your ad choices. Visit megaphone.fm/adchoices
