The charming name of these spiders comes from the type of web that females construct for their babies. Before their eggs hatch, female nursery web spiders carry their egg sac in their jaws. Then they construct a shelter for the new hatchlings out of leaves and webbing, and stand guard over it.

Nursery web spiders are among the largest of the true spiders.
