Hobo Spiders: Identification, Behavior & Bite Risks - Pacific Northwest

Hobo spiders (_Eratigena agrestis_) are a species of funnel-web spiders that can be found in the Pacific Northwest of North America, including but not limited to, Washington, Oregon, and British Columbia. They are known for their aggressive behavior, and their bites can cause serious medical complications, including tissue necrosis and skin ulcers. Hobo spiders are typically brown in color, with a pale yellow or orange marking on their abdomen. They can grow up to 2.5 cm in body length, and they have a leg span of up to 10 cm. Hobo spiders typically build their webs in dark, secluded areas, such as under rocks, logs, and leaves. They are active hunters, and they typically prey on insects and other small invertebrates. Hobo spiders are not considered to be a major threat to humans, but their bites can cause serious medical complications. It is important to seek medical attention if you are bitten by a hobo spider.
