The Hobo spider (Tegenaria agrestis) is aggressive and its venom is highly toxic to human beings. It is not a member of the wolf spiders. Instead, it is a member of the family Agelenidae. Members of this family construct a funnel web, and typically lurk in the narrow end of the funnel, waiting for an insect to touch the outer part of their web.
