Wolf spiders are members of the family Lycosidae, from the Greek meaning "wolf". They are robust and agile hunters with good eyesight. They live mostly solitary lives and hunt alone. Some are opportunistic wanderer hunters, pouncing upon prey as they find it or chasing it over short distances. Others lie in wait for passing prey, often from or near the mouth of a burrow. Wolf spiders resemble Nursery web spiders (family Pisauridae), but they carry their egg sacs by attaching them to their spinnerets (Pisauridae carry their egg sacs with their chelicerae and pedipalps). Wolf spiders have two eyes out of eight that are large and prominent. The eight eyes of the Nursery web spiders are all of approximately equal size. Wolf spiders are unique in carrying their eggs along with them in a round silken globe, or egg sac, which they attach to the spinnerets at the end of their abdomen. The abdomen must be held in a raised position to keep the egg case from dragging on the ground, but they are still capable of hunting while so encumbered. Also unique to wolf spiders is their method of infant care. Immediately after the little spiders hatch and emerge from their protective silken case, they clamber up their mother's legs and all crowd onto her abdomen. Wolf spiders can be found in a wide range of habitats both coastal and inland. These include shrublands, woodland, wet coastal forest, alpine meadows, and suburban gardens. Spiderlings disperse aerially and consequently wolf spiders have wide distributions. Wolf spiders will inject venom freely if continually provoked. Symptoms of their venomous bite include swelling, mild pain and itching. Though usually considered harmless to humans, the bite of some species may be painful. Their eyes reflect light well, and one method of finding them is to hunt at night using a flashlight strapped to one's forehead so that the light from the flashlight is reflected from their eyes directly back toward its source. This is also especially helpful because the wolf spiders are nocturnal and will be out hunting for food, making it easier to find them. [READ THE REST OF THIS ARTICLE]
