![]() ![]() “It’s possible that the silk trail is more useful than we thought,” Ms. One question that remains: Can males determine how long ago a rival produced the silk trail? It may be that a rival’s trail provides temporal as well as geographical information, signaling to followers whether they will be too late to get to a female, or whether speeding up can still get them to the business of breeding. “The chemicals on male black widow’s silk threads are species-specific,” Ms. And the males seemed to know when the trails were left by other black widows rather than by males of other species. Ninety-five percent of male black widows chose to follow the paths made by their rivals, even when the pheromones were readily detectable. The males were given two options in a maze: follow the silk threads of a rival black widow male, or avoid the rival’s trail and instead rely on direct personal signals from a female, which were blown in his direction with a fan. Scott and her colleagues repeated the race in the lab, where the conditions of the males’ journey to the web could be more tightly controlled. “So following this path is more efficient than trying to make their own way, climbing over obstacles and making sure they are still going in the right direction just based on pheromones carried by the wind.” “The silk threads act like a highway connecting the tops of plants,” Ms. “It makes sense for them to try to use all the tricks they can to find females as soon as possible, even if there are other males that have already found her.” “Males have to race to find females,” said Catherine Scott, an arachnologist at the University of Toronto Scarborough in Canada and the study’s lead author. Researchers found that male black widows find potential mates faster by following the silk trails left behind by other males. Why not simply avoid the competition and seek out females’ webs empty of other males? But male black widows actually seem to thrive on the competition, according to a study published Wednesday in the Proceedings of the Royal Society B: Biological Sciences. They deposit “mating plugs” in the female’s body to block rival sperm. The males slash the female’s webs to make them less enticing to others.
