[[Image:Wolf spiders courtin.jpg|thumb|150px|left|Courtship of the wolf spiders]][[Image:Wolf_spider_with_big_egg_sac.jpg|thumb|150px|left|Female carrying a large egg sac]] Mating generally begins outside the female's burrow at night. Males are first attracted by the pheremones of the female. Then they begin a courtship ritual in which he will tap his legs in a certain way, drum with his palps, and create sounds by scraping the palp against itself (also called stridulation).

The female wolf spider lays eggs in a large sac, which can be nearly as large as her own body. She attaches the egg sac to her body, and carries it until the eggs hatch. She then tears open the egg sac and the newly hatched spiders climb onto her back where they remain for up to a week [http://www.everythingabout.net/articles/biology/animals/arthropods/arachnids/spiders/wolf_spider/]
Mating takes place outside the female's burrow at night. Some adult male Wolf spiders of smaller-sized species are known to disperse by air in order to find mates. The male is attracted by scent markings left by the female, often associated with her drag-line silk. Males perform a courtship ritual prior to mating, often involving complex leg and palp signalling to the female.


The female constructs an egg sac of white papery silk, shaped like a ball with an obvious circular seam, which she then carries around attached with strong silk to her spinnerets. When the spiderlings hatch, they are carried around on the female's back until they are ready to disperse by ballooning or on the ground. Such a high degree of parental care is relatively unusual among spiders.
