Phidippus audax is a jumping spider commonly found in Utah. It is frequently referred to as the Daring Jumping Spider, or Bold Jumping Spider. The average size of an adult Daring Jumping Spider can be anywhere from 13 to 20 mm in length.
Daring Jumping Spiders are typically very small, black and hairy looking with a pattern of spots and/or stripes on their abdomen and legs. Often these spots are a bright orange or red color when the spider is young and they turn white or light grey as the spider grows older. Another unique feature of the Daring Jumping Spider is their bright metallic green or blue, iridescent chelicerae.
The Daring Jumping Spider’s name suits him perfectly. These spiders have been known to jump up to 50 times their own body length. They move extremely fast and seem to prefer jumping to crawling.
Similar to other jumping spiders, they have large, forward facing eyes which allows them very good stereoscopic vision. This gives them an advantage when stalking prey, and allows some visual communication with other jumping spiders.
Are they Poisonous?
Due to it’s dark color, hairy appendages and brightly colored spots, the Daring Jumping Spider is often mistaken for being dangerous, but in reality they are not. The Daring Jumping Spider is not poisonous to humans. Like many spiders, a Daring Jumping Spider will not go out of his way to attack a human unless they feel threatened or in danger. However, if a person is bitten and they are known to be allergic to spider venom, it’s still a good idea to get the bite checked out ASAP.
