If you squash a female wolf spider, hundreds of baby spiders could be released into your home. It appears that the choice of whether to eat or mate with a female spider is based on the higher reproductive possibility. Wolf spiders exhibit unique parental care behaviors. However, males often survive to mate again. The older, less productive female spiders were instead eaten by the male spider. / SPIDERS / WOLF SPIDERS Wolf Spider Life Cycle Life Cycle & Reproduction Mating for wolf spiders is a dangerous affair because males are sometimes killed and consumed by females following mating.
