There’s Another Spider That Destroys Female Genitalia
The discovery suggests that maiming females is a widespread strategy for male arachnids, scientists say.
Spiders have some pretty strange mating habits, from sexual cannibalism to self-sacrifice.
Now, a new study suggests we can add another oddity to the list—destroying female genitalia.
Some male Cyclosa argenteoalba, a type of orb-web spider, maim their mates’ private parts after sex in what may be an attempt to prevent other males from copulating with her.
The study, published recently in Biology Letters, builds on a 2015 research that revealed the same behavior in a different kind of orb-weaving spider, Larinia jeskovi. (See “This Spider Destroys Female Genitalia to Prevent Future Mating.”)
However, the orb-weaving spider’s genital destruction seems to be a newly discovered technique, says Kensuke Nakata, a zoologist at Kyoto Women’s University who conducted the
