Wolf Spider Identification
Approximately 200 known species belong to the Family Lycosidae in the U.S. and Canada. These wolf spiders are particularly abundant in prairie areas but can be located in a variety of habitats. They are commonly mistaken for nursery web and fishing spiders. They may also be confused with brown recluse spiders.
It can be difficult to differentiate between wolf spiders and the many species that resemble them. Most spiders have in common two-segmented bodies, eight legs and fang-like mouthparts known as chelicerae. However, wolf spiders do have shorter legs than web-building spiders and appear more robust than other species. Wolf spiders are also large and hairy. Their bodies are commonly patterned in black, gray and brown hues.
It may help to observe the movements of the spider in question. Named for their swift motion, particularly while attacking prey, the wolf spider can sometimes be seen scurrying across open surfaces. The brown recluse, on the other hand, tends to hide in dark, unvisited places and is rarely seen in the open. Recluses also have six eyes arranged in pairs combined with a violin marking on their cephalothoraxes. Wolf spiders do not have these combined characters.
