Life Cycle
The male courts potential mates by rhythmically waving his pedipalps. The female spins a spherical egg sac, attaches it to her spinnerets, and drags it about until the spiderlings emerge. The young clamber about on the female’s back and are carried until they are ready to disperse (see below).

Remarks
Most wolf spiders live on the ground and hunt for prey at night. Their dark mottled colors help camouflage them among the leaves. Except for one genus, wolf spiders do not spin webs. Some dig burrows in the ground, others make holes under rocks, and many have no retreat at all.
