Rafael Rios Moura says spider moms handle most of the parental care, but not the Manogea porracea species he studied. Both spider parents take responsibility to protect their egg sac. Linda Rayor of Cornell University said, “To the best of my knowledge, there really aren’t other examples where male spiders step up to care for young or eggs.” Sometimes at the cost of their own lives, male Manogea porracea switch from solitary life to a dad-web upstairs, brushing rainwater off egg sacs. Moura hypothesizes that the females are very delicious to predators considering that many females disappeared by the end of breeding season.
