Although the toxicity and aggression of the hobo spider have long been debated, there is little evidence that the hobo spider is a dangerously venomous species. [2] The CDC reported case studies in the 1990s claiming that the hobo spider bite caused isolated cases of necrosis in people, [ 12 ] [ 13 ] but as of 2017, the CDC no longer lists the ...
The Agelenidae are a large family of spiders in the suborder Araneomorphae.Well-known examples include the common "grass spiders" of the genus Agelenopsis.Nearly all Agelenidae are harmless to humans, but the bite of the hobo spider (Eratigena agrestis) may be medically significant, and some evidence suggests it might cause necrotic lesions, [1] but the matter remains subject to debate.

Eratigena is a genus of spider in the family Agelenidae.Most of its species were moved from the genus Tegenaria in 2013, of which the genus name is an anagram. [2] Two species that frequently build webs in and around human dwellings are now placed in this genus: the hobo spider (Eratigena agrestis), native to Europe and Central Asia and introduced to North America, and the giant house spider ...
Hobo spider. What they look like: Hobo spiders are tannish-brown and the top of the spider may look mottled, with darker and lighter spots, Potzler says. They look pretty hairy and have spiny ...
The hobo spider and the yellow sac spider have also been reported to cause necrotic bites. However, the bites from these spiders are not known to produce the severe symptoms that can follow from a recluse spider bite, and the level of danger posed by these has been called into question. [40] [41]
Male hobo spider ‒ note the large pedipalps. The hobo spider, Eratigena agrestis, may wander away from its web, especially in the fall, and thus come into contact with people. The Centers for Disease Control [45] blamed the hobo spider in three reports of necrotic "bites" in the Pacific Northwest of the United States between 1988 and 1996 ...
The majority of these were moved to Eratigena, [3] including the giant house spider (Eratigena atrica) and the hobo spider (Eratigena agrestis). [1] They can be difficult to identify because they resemble wolf spiders and other funnel-web spiders in their area, [4] unless found in an area where they do not occur naturally. [5]
A cellar spider which has captured a house spider, in a domestic setting. The predator spider has noticeably grown in abdomen size during feeding, whilst the prey appears diminished. Pholcids may be beneficial to humans living in regions with dense hobo spider populations as predation on Tegenaria may keep populations in check. [12]
