Description: The keys to the identification of the Hobo Spider will be the eye arrangement and the pattern of darker “fishbone” or chevron stripes on their upper abdomen. The 8 eyes are in two parallel rows of 4 ocelli across the front of the cephalothorax, with both rows forming straight lines. This has become a very common spider in homes especially in basements, crawl spaces, and other lower areas of the structures.
Biology: It is one of a small number of spiders in North America whose bites are generally considered to be medically significant. Although this species of spider has a reputation for aggressiveness, they will normally avoid contact with humans. Most bites occur when the spider is accidentally crushed or squeezed by a human. The bite from the Hobo Spider appears to be capable of causing a fairly severe necrotic wound. Untreated, the wound could take up to six months to finally run its course and begin to heal, but with the proper treatment the effect should be greatly reduced.
Habits: It is a member of the genus of spiders known colloquially as funnel web spiders. Individuals construct a funnel-shaped structure of silk sheeting and lie in wait at the small end of the funnel for prey insects to blunder onto their webs. It can be a fast running and fairly aggressive spider, biting with less of a reason than most other hunting spiders need.
