not appear to affect their mating success or make them more inclined to mate, most likely because they sense mate, plant, and human odors to be distinctive. E. culicivora has this adaptive timing in order to facilitate efficient predation to obtain high-quality prey in a timely manner. Mating Mate choice In contrast to most jumping spiders, mating behavior in Evarcha culicivora is very violent. Cannibalism of both sexes are more common than other spider species. The frequency with which males kill females is higher than that of females killing males. Therefore, to ensure reproductive success, Evarcha culicivora has evolved a mate choice strategy. Larger males are more likely to engage in cannibalism towards females. Therefore, body size is a direct indicator of the degree of dangerousness and survival advantage. Evarcha culicivora must make some trade-offs between successful offspring and their safety after mating. Virginity is also an important variable in mate choice. Virgin males and females are willing to take risks by choosing the opposite sex individual with larger body size. However, previously mated individuals prefer safe partners with smaller body size. Sexual cannibalism Sexual cannibalism only occurs in a small proportion of E. culicivora spiders, but their sexual cannibalism behavior is different from most other spiders. In E. culicivora, males are more likely to be the predators and females respond to them as prey. Sexual cannibalism in E. culicivora mainly happens when two individuals have different body lengths and normally the bigger one is the predator. There are a few common scenarios of sexual cannibalism in E. culicivora: 1) The predator stalks the prey and attacks the prey before the prey is aware. There is no further interaction before the encounter. 2) The male predator displays at the quiescent female at a distance and when he gets close, he suddenly shifts to a predatorial stance, thereby attacking the female. 3) The male predator mounts and initiates postmount courtship with the female. He then kills the quiescent female. 4) The male predator suddenly kills the female during copulation. After biting or killing, the male predator may eat the female, walk away without eating her, continue copulating and then eat her, or continue copulating without eating her. Male-female interaction and copulation It is common in salticids that males initiate male-female interactions by displaying first. In E. culicivora specifically, the initiation of male-female interactions vary by gender, as it is not always
