Wolf spiders are members of the family Lycosidae (from the Ancient Greek lúkos, meaning "wolf"), named for their robust hunting skills and sharp eyesight. These spiders live mostly in solitude, hunting alone without spinning webs. Some are opportunistic predators, chasing prey across short distances or pouncing when prey is within reach, while others lie in wait near burrow entrances. Wolf Spider Description The body size of wolf spiders varies widely across their many genera, ranging from less than 10 mm to 35 mm (0.4 to 1.38 inches), excluding the legs. Their eye arrangement is a key identifying feature, with eight eyes organized in three rows: Bottom row: Four small eyes. Middle row: Two large eyes (helpful for distinguishing them from Pisauridae spiders). Top row: Two medium-sized eyes. These spiders have excellent eyesight compared to most other spiders. Their tapetum lucidum—a retroreflective tissue in four of their secondary eyes—creates a characteristic eyeshine when light is reflected directly back toward the source, such as from a flashlight beam. This feature, also found in animals like cats, makes wolf spiders easy to spot at night. Wolf spiders are among the best-sighted spiders, surpassed only by jumping spiders (Salticidae) and huntsman spiders (Sparassidae), with jumping spiders even capable of distinguishing colors. Habitat and Behavior Wolf spiders are highly adaptable, found in environments ranging from dry inland deserts to alpine meadows and coastal forests. They are common in lawns, gardens, shrublands, and woodlands, and some species, like Tasmanicosa godeffroyi and Venatrix furcillata, thrive in suburban areas. Some wolf spiders make burrows, with variations in construction depending on the environment: In arid regions, they build turrets around their burrow entrances to divert floodwaters. Others plug burrows with pebbles or construct twig palisades for extra protection. Species like the Grey Wolf Spider (Dingosa simsoni) leave their circular trapdoors open when out hunting. During autumn, male wolf spiders often wander into homes and buildings searching for mates. Diet and Ecological Role Wolf spiders are generalist hunters, primarily feeding on small ground-dwelling insects and other invertebrates. They play an essential role in natural pest control within gardens and farms, making them beneficial to the environment. Remarkably, some wolf spider species are known to prey on cane toads: Reproduction and Life Cycle Female wolf spiders are known for their maternal care, which is uncommon among spiders. They create a silken egg sac that they attach to their spinnerets, carrying it with them as they hunt. To keep the egg sac from dragging on the ground, the female must lift her abdomen, an impressive feat that doesn’t hinder her ability to hunt. When the spiderlings hatch, they climb onto the mother's back and remain there for several weeks until they are ready to disperse. They may leave the mother by ballooning on air currents or moving across the ground. Most wolf spiders have a lifespan of up to two years. Mating typically takes place at night, and males are drawn to females by scent markings left on drag-line silk. Some male wolf spiders even disperse by air to find a mate. Before mating, males perform elaborate courtship rituals using their legs and palps to signal the female. Venom and Danger to Humans Wolf spider bites are generally not dangerous to humans. Most bites cause mild pain, swelling, and itchiness, though rare cases may involve dizziness, rapid pulse, and nausea. Necrotic wounds were once attributed to some wolf spiders in Australia and South America, but further research suggests these symptoms were likely caused by other spider families or unrelated conditions. If symptoms persist following a wolf spider bite, seek medical attention for evaluation. Control and Prevention Although wolf spiders are beneficial predators, they can occasionally become unwelcome guests in homes and gardens.
