Wolf spiders typically lay their eggs in the midsummers. The female spider will spin a silken sac to deposit her eggs. Once the sac is full, she will seal it shut and remain with it until the eggs hatch. When the spiderlings emerge, they will climb up their mother's legs and onto her back, where they will ride for several weeks until they are large enough to fend for themselves. Some species of wolf spiders will overwinter as nymphs (immature spiders), while others will overwinter as adults.
