He may pluck her web suggestively, so she knows he’s a potential mate rather than a potential meal. They approach the web of a female in response to pheromones, or chemical signals, that she emits. Web-building species leave their webs and wander about looking for mature females. ‘To open the epigyne they have to have all the right bits.' Out on the townīut before he gets that far, the male spider has to find a willing mate. ‘It’s a lock and key,’ says spider expert Stuart Hine. The shape of pedipalps varies between species, and males must have the right equipment for the job. Females will have a fully developed epigyne - a structure on the underside of their abdomen for receiving the male's pedipalps and sperm. Males will also develop enlarged pedipalps, which are small appendages in front of their legs used for mating and transferring sperm. Longer limbs are useful for this stage of their lives as they have to cover a lot of ground looking for a mate. When they’re ready to mate, both sexes go through a final moult.īy the time the males have completed their final moult they have generally lost body mass but have longer legs than before.
