Which spiders eat their mates?
For male widow spiders, mating is an infamously dangerous activity. In these species, which include the black widow and redback, the large females will often devour the smaller males during sex—hence the “widow” in their names. In some cases, the female catches the male while he’s trying to escape.
Do writing spiders kill their mates?
In many spider species, females eat the males after sex. Big females eat their puny mates simply because a) they’re hungry and b) they can. Wilder and Rypstra found that among the wolf spider (Hogna helluo), large males were never eaten by their mates, while small males were consumed 80 percent of the time.

As is the case with Allocosa brasiliensis, males cull older females who are less fertile than their young counterparts. Offspring of the species Stegodyphus lineatus eat their mother.
How often does a wolf spider eat its mate?
Wilder and Rypstra found that among the wolf spider ( Hogna helluo ), large males were never eaten by their mates, while small males were consumed 80 percent of the time. Discovering this, the researchers then pored over the literature and found the size rule to hold true in a wide range of spider species.
Why do some spiders survive after they mate?
While most males don’t survive after mating, a few do. This is because they either swim away quickly or mate from a distance with their mating arm (known officially as the hectocotylus) to escape the grip of the female later. Black widow spiders are some of the most venomous spiders to exist.
