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 competition. Strategies can be either based on one’s own abilities (self assessment) or on the relative abilities of two opponents (mutual assessment).
