Overview
Biology
Hobo Spiders build funnel-shaped webs with a narrow retreat where they hide. Females lay eggs in silken sacs, which they protect until they hatch. Hobo Spiders are ground-dwellers and often create webs near the ground in dark, secluded areas.
Food
Hobo Spiders are active hunters and primarily feed on insects. They wait for prey to enter their funnel web, then quickly rush out to capture and inject venom into their prey. They consume the liquefied internal tissues of their prey.
The Hobo Spider, Eratigena agrestis, is a member of the funnel-web spider family and is known for its potentially harmful bite, which can cause necrotic lesions in some cases. They are common in the northwestern United States and parts of Europe.
Description
Hobo Spiders are medium-sized, with body lengths ranging from 0.3 to 0.6 inches. They are brown with a mottled pattern on their abdomens and have long, hairy legs. They lack distinctive markings, making them difficult to identify without close examination.
Habitat
Hobo Spiders prefer dark, moist environments such as basements, crawl spaces, and woodpiles. They are also found outdoors under rocks, logs, and debris. They tend to avoid human activity and build their webs in undisturbed areas.
