While males rarely live beyond one year, female wolf spiders may live for several. Once she has mated, the female will lay a clutch of eggs and wrap them in a round, silk ball. She attaches the egg case to the underside of her abdomen, using her spinnerets to hold it in place. In fact, this behavior is characteristic of wolf spiders. Burrowing wolf spiders place their egg sacs in the tunnel by night, but bring them to the surface for warmth during the day. When the spiderlings hatch, they climb onto the mother's back until they have grown enough to venture out on their own.
