Hobo spiders have a light stripe running down the middle of the sternum. If the spider instead has three or four pairs of light spots on the lateral portions of the sternum, then it is one of the other two related Eratigena species. However absence of spots is not conclusive proof that the spider is a hobo spider, since the spots on other ...
Giant house spiders may compete with hobo spiders for the same resources. Hobo spiders grow no more than a body size of 15 millimeters (0.59 in) long whereas the larger female giant house spider can have a body size of 18 millimeters (0.71 in), [ 15 ] but has proportionately much longer legs.
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 ...
Joro spiders from East Asia are weaving their way into the U.S. landscape. Understand their habits, habitats, and how they affect local ecosystems. Creepy, crawly and invasive.
“The hobo spider can inflict a painful bite that results in localized red swelling and some pain, but no necrotic lesion,” Potzler says. Usually, symptoms will get better within 24 hours with ...
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. [2]
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 ]
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 ...
