A bite by Argiope aurantia is comparable to a bee sting with redness and swelling. For a healthy adult, a bite is not considered an issue. Though these spiders are not aggressive, people who are very young, elderly, or who have compromised immune systems should exercise caution, just as they would around a beehive or a hornet nest.

Children are more sensitive to the venom of wandering spiders. The spiders often make threatening gestures, such as raising up their legs, or hopping sideways on the ground, which might amuse a child to the point of reaching towards the spider.

Jumping spiders also have some form of color vision, with each layer responsible for a different color sensitivity/ recognition. [15] In general, jumping spiders are able to see with a high level of spatial resolution that is incomparable to any other species similar to it in size. [3] This explains why jumping spiders are predators and hunt.
While roughly 3,000 species of spiders are found throughout the U.S., very few pose a direct threat to humans. Spider bites are rare, and medically significant incidents are even less common ...
Common house spiders will bite humans only in self-defense, when grabbed and squeezed. [citation needed] The species' synanthropic habits, however, increase the risk of human bites. [2] Common house spiders possess poor vision and cannot detect any movement more than three to four inches away. If cornered, they will feign death as last resort.
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.
