The Hobo spider, a light brown spider with a yellowish-green tint on its abdomen, ranges in size from 0.4 in. (1 cm) to 0.6 in. (1.5 cm). Hobo, or Northwestern brown, spiders (Tegenaria agrestis) are common and widespread in Europe and western central Asia. Since their introduction to North America in the early 1900s, hobo spiders have spread to British Columbia, Alaska, Oregon, Idaho, Montana, and Utah. These spiders build funnel webs in wood, rock, or debris piles.
