These athletic spiders don’t spin webs to catch their prey; instead, they run it down! They have long legs and are usually gray, brown, black or tan with dark brown or black body markings (especially stripes).
The female wolf spider carries her egg sac in a unique way: She attaches it to her spinnerets at the bottom rear of her abdomen. Later, she carries her babies on her back.
The eye configuration is similar to that of jumping spiders: The two center eyes of the top row are enlarged. But unlike jumpers, wolf spiders have a row of four small eyes below the four larger ones. Also, wolf spiders run smoothly over the ground and often hunt at night, while jumpers hunt in plants during the day, move jerkily and jump great distances.
Other similar spiders: Tarantulas are much larger and heavier. Fishing spiders carry their egg sacs in their jaws, swim in and walk on water, don't carry their babies on their backs, and don't have the two large forward-facing eyes.
