Why do female spiders eat males after mating?
This behavior may be triggered by aggression, where females carry over hostility from their juvenile state and consume males just as they would prey. Sih and Johnson surmise that non-reproductive cannibalism can occur due to a remnant of an aggression trait in juvenile females.
Why do female bugs eat their mates?
Turns out the motivation for this creepy cannibalism is much simpler. It’s all about size. If males are small, they’re easier to catch and therefore more likely to be prey, say Shawn Wilder and Ann Rypstra from Miami University in Ohio. Big females eat their puny mates simply because a) they’re hungry and b) they can.
What animal eats male after mating?
The nutrients gained when a female praying mantis eats her suitor benefit her offspring as they grow. Sexual cannibalism — when the female of a species consumes the male during or after mating — is also known among spiders, such as the black widow, and scorpions.
