![]() Colored markings may appear along their bodies. There are several wolf spiders found in the west that are most commonly brown in color, although gray and black specimens have also been documented. Because wolf spiderlings travel great distances, the habitat of a single species can span a large region. Coastal sand dunes, mountain herb fields or riverbank gravel beds are also home to many wolf spider species. Some wolf spider species prefer to dwell in suburban gardens. Wolf spider habitats range from woodlands and dry, inland shrub lands to wet, coastal forests and alpine meadows. In most cases the wolf spider will first retreat or rear up on its legs, exposing its large fangs. Wolf spiders typically do not bite unless threatened or provoked. BitesĪlthough their reputation would lead one to believe otherwise, the bite of the wolf spider is not a significant medical threat to the average adult. Hemolymph is pumped through the heart and bathes the internal organs and tissues. The circulatory system of the wolf spider is open, meaning the blood isn’t confined and delivered inside of a closed system, and contains hemolymph, a respiratory protein similar in function to hemoglobin. Also present near the jaw are the palps, which serve as sensory structures and as sperm storage in the male wolf spider. Two sharp, horizontal fangs are present at the extreme bottom of these jaws. Jaws & fangsĬhelicerae, or jaws, are used to hold prey, inject venom and eat. Wolf spiders do not have these combined characters. Recluses also have six eyes arranged in pairs combined with a violin marking on their cephalothoraxes. The brown recluse, on the other hand, tends to hide in dark, unvisited places and is rarely seen in the open. Named for their swift motion, particularly while attacking prey, the wolf spider can sometimes be seen scurrying across open surfaces. It may help to observe the movements of the spider in question. However, wolf spiders do have shorter legs than web-building spiders and appear more robust than other species. Most spiders have in common two-segmented bodies, eight legs and fang-like mouthparts known as chelicerae. It can be difficult to differentiate between wolf spiders and the many species that resemble them. Wolf spiders are also sometimes confused for tarantulas, nursery web and fishing spiders, and brown recluse spiders. ![]() Size: Wolf spiders are hairy arachnids that can grow up to 35 mm in body length.Ĭolor: Their bodies are commonly patterned in black, gray and brown hues.īody: Quick moving and relatively large in size, wolf spiders often inspire fear when they are found within human dwellings.Įyes: The eight noncompound eyes of the wolf spider are arranged with one lower row of four small eyes, two larger eyes and two more small eyes on top of the head.
