Similar to black widows, redback spider females often consume their mates. During mating, the male even assists the female by positioning himself to be eaten, which might increase the chances of successful sperm transfer.

In the deep sea, male anglerfish are much smaller than females and will attach themselves to the female with their sharp teeth. Over time, the male becomes a parasitic appendage, eventually being absorbed into the female's body to provide sperm when needed.

In some grasshopper species, females may eat the male after or even during mating. This behavior is thought to be driven by the female's need for additional nutrients to support reproduction.

Wolf spiders are another group where sexual cannibalism can occur. The female sometimes consumes the male after mating, which could provide her with energy to produce and care for her offspring.

Jumping spiders are known for their complex courtship dances, but in some species, the female may eat the male after mating. This can serve as a nutritional boost for the female and increase the survival rate of her young.
