Strategies for reducing this sperm competition include mating-induced sexual inhibition in females, and this has been found in many insects and spiders in many spider species, females that have mated become unreceptive and aggressive to males however, the long-term impact of mating on future. That's a phenomenon in which females are uninterested in—or even aggressive toward—potential additional mates immediately after mating it's been studied in species like fruit flies, moths and even hamsters, and scientists think that it's a way males can reduce the amount of competition their sperm faces.

The jumping spider phidippus clarus uses signals that combine visual and substrate-borne vibrations, which predict the outcome of male–male competition and substrate-borne aggressive vibrations predict success in male–male contests with heavier males that signal more being more likely to win contests ( elias et al.

Phidippus clarus are jumping spiders in which males produce multimodal (visual and vibrational) signals in both male– male (aggressive) and male–female ( courtship) contexts the p clarus mating system is complex, with sex ratios and the level of male compe- tition changing over the course of the breeding season. It seems the first time's the charm for the female australian jumping spider a recent study by vivian mendez and her colleagues at macquarie university, australia, found that most female servaea incana spiders only mate once in their lifetime, after which they become unwilling or even aggressive toward males who try to.
