Hobo Spider

• The female reaches sizes of 11–15 mm (.43–.6 in); the male 8–11 mm (.31–.43 in).
• The hobo spider (Tegenaria agrestis) is a member of the genus of spiders known colloquially as funnel web spiders.
• It is one of a small number of spiders in North America whose bites are generally considered to be medically significant.
• 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.
• Hobo spiders sometimes build their webs in or around human habitations.
• 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 spider´s venom is strong enough to cause considerable local pain and has been reported to sometimes cause tissue death (necrosis) at and near the bite
