Wolf spiders capture prey by hunting them, not by catching them in a web. Two of their eight eyes are enlarged, giving them excellent eyesight with which to locate prey. Typically wolf spiders are solitary, and hunt alone. The females carry their white egg sac with their spinnerets, which are located at the tip of their abdomen (and are also the structures through which silk leaves their body). You can tell them from similar looking nursery web spiders by how they transport their egg sacs. Nursery web spiders carry their egg sacs in their chelicerae, or mouthparts and pedipalps (front appendages which resemble legs).
