Mаny species оf jumping spider use signаls thаt cоmbine visual and substrate-bоrne vibrations, which predict the outcome of male–male competition and are important to copulation success. These courtship rituals are a multi-sensory sort of 'dance' that males use to woo potential mates. Two related types (but separate biological species) of jumping spiders have very different dance and sound rituals - such that if a male of species A dances for a female of species B - this often results in predation in which the female kills and consumes the male. This also often happens in the opposite case (female of species A/ male of species B). What kind of reproductive isolation is this?
