In general, they are long-legged and covered with short hairs, gray to brown to dark brown, and with several darker stripes running longitudinally on the cephalothorax. Identification: Wolf spiders vary in size from small species with only ½ inch leg spans to large ones whose legs may stretch out 5 inches. They commonly enter structures and can be found running across floors or walls as they search for food. Retreats for the spiders are holes in the soil, under debris on the ground, or within wood piles. Smaller species may even “run” across the water of a swimming pool, suspended on the surface tension of the water. They are capable of biting humans but the venom is not considered dangerous, but their aggressive behavior makes wolf spiders some of the most feared by people. Some species of wolf spiders may have leg spans of 4 inches or more and they are very mobile, very fast, and very aggressive when threatened. Once the eggs hatch the mother then cuts a slit in the sac to allow her young to emerge, and they then climb onto her abdomen to be carried around for up to 2 weeks. The females create the tough egg sac and then carry it attached to the tip of the abdomen. Origin: There are over 200 species of wolf spiders found north of Mexico, and these often are the most common spiders in cold climates of high mountains or far northern regions.īiology: Wolf spiders are hunters, and use their silk only for lining a nest and for covering their eggs.
