Difference Between Brown Recluse and Wolf Spider

The Difference Between Brown Recluse and Wolf Spiders

Many people confuse brown recluse and wolf spiders, due to their similar morphology. Although they come from the same family and share many characteristics, there are some key differences between the two species.

The brown recluse spider, Loxosceles reclusa, is a venomous spider native to the United States. It is characterized by its violin-shaped marking on the top of its head and abdomen. It is usually a light- to medium-brown color and can range from 3-12 mm in body length. Brown recluse spiders are known to inhabit dark, undisturbed areas such as closets, attics, basements, and woodpiles.

The wolf spider, Lycosidae, is a species of spider found throughout the world in a variety of habitats. They are generally dark brown in color and, depending on the species, can range from 1-35 mm in length. Wolf spiders are often found outdoors in wooded areas, fields, and gardens.

The primary difference between a brown recluse and a wolf spider is their venom. Brown recluse spiders have a potent venom that can cause severe skin necrosis and systemic reactions if the bite is not treated immediately. Wolf spiders, on the other hand, have a mild venom that is not harmful to humans.

In addition to their venom, the two spiders differ in their behavior. Brown recluse spiders are shy and reclusive and tend to hide during the day, while wolf spiders are more active during the day and are often seen hunting for prey.

Finally, the two species differ in their web-building behavior. Brown recluse spiders weave webs to capture their prey, while wolf spiders do not build webs, but instead hunt and stalk their prey.

In summary, although brown recluse spiders and wolf spiders are similar in appearance, they have distinct differences in their venom, behavior, and web-building behavior. It is important to be able to identify each species in order to avoid potential danger.

Spiders’ Appearance

The brown recluse spider (Loxosceles reclusa) is easily identified by its brown color and violin-shaped marking on its back. Its legs are long, thin and yellowish-brown. Its body is also small and measures about ¼ inch in length. The wolf spider is typically gray or brown and may have black stripes or markings. It is a larger spider than the brown recluse and measures up to 1-2 inches in body length.

Biology and Habitat

The brown recluse spider is native to the Midwest and Southeastern United States. It can be found in dark, undisturbed areas in homes, such as attics, closets, cellars, or garages. The wolf spider is found throughout the United States and prefers to live in grassy or wooded areas.

Bite and Poisonousness

The brown recluse spider is poisonous and its bite can be dangerous to humans. Its bite can cause severe pain, swelling, itching, and blistering. It can also lead to an open wound that may take several weeks to heal. The wolf spider is not poisonous and its bite is not dangerous to humans. It may cause some mild pain, itching, and swelling, but the symptoms will typically subside with in a few days.
