Black Widows Are Infamous For A Reason
When the smaller males approach the female’s web, they have to take precautions. If they’re not careful, the black widow female might mistake them for prey and eat them. But that’s part of this strange animal courtship ritual, and if you’re not mistaken for prey, then you’ve made it past the first step. To keep themselves safe, males announce their presence with vigorous rump shaking. When they step onto the web, they vibrate their abdomen which sends signals across the silk strands. He’ll do a series of repetitive vibrating movements that are starkly different from the trapped prey. Sometimes, though, the female will devour the male during their courtship. Mating with a black widow is a dangerous activity, and males have to take extreme precautions. Males are so dedicated to finding a female mate, that many of them die during their pursuit. Their main goal is to avoid being cannibalized during sex and impregnate their female counterpart (National Geographic).
