Wolf Spiders: Maternal Duties Coming To An End

6-28-17 wolf spider 069Just a few days ago, this adult female wolf spider’s abdomen was covered three-spiders-deep with newborn wolf spiderlings. Wolf spiders, unlike most spiders, do not abandon their eggs. They carry their egg sac around with them until the eggs hatch, grasping it with spinnerets located at the tip of their abdomen. Not only does the female not desert her eggs, but she also provides protection for her newborn spiders. After hatching, the several dozen or more young crawl up onto her abdomen, where they ride around for several days. Eventually they drop off and begin a life of their own. In this photo, only three spiderlings remain (look closely) and they abandoned ship within the hour.
