[1][2] Like all jumping spiders, they have excellent stereoscopic vision that aids them in stalking prey and facilitates visual communication with potential mates during courting.

[1] Bold jumping spiders are native to North America and have been introduced to Hawaii, Nicobar Islands, Azores, and the Netherlands.

[3] Bold jumping spiders are solitary carnivores that use their highly specialized eyesight to actively hunt and stalk prey.

[3] They prey on a variety of insects and non-insect terrestrial arthropods such as caterpillars, dragonflies, grasshoppers, and other spiders.

[3][6][2] They are one of the most common spiders found in agricultural areas and have been studied to determine their impact on crop pest populations.

[6] These spiders can be found in temperate climates in a variety of terrestrial habitats including grasslands, chaparrals, open woodlands, and agricultural fields.

[3][4][2] The bold jumper is one of the most commonly occurring spider species within its range and is often found living in close proximity to humans.

[11] In 1845, Nicholas Marcellus Hentz published his work describing a species he called Attus audax.

[4] These species were distinguished by the presence of partial vertical ridges in the central distal part of the palea.

[4] The presence of a distinct white triangle in the center of the back with two smaller spots below it is often used to distinguish this species.

[1] Their unique visual system is widely regarded as the best amongst all spiders and plays an important role in courtship, hunting, and observational learning.

[1] Bold jumpers will quickly flee from animals that are too large to eat, jumping down and away or hiding in small crevices.

At night they hide in a crevice or small cavity and make a silk retreat to avoid predators that hunt by touch.

[19][2] Bold jumpers prey on a variety of insects and non-insect terrestrial arthropods such as caterpillars, dragonflies, grasshoppers, and other spiders.

[19] Once close enough, it crouches and releases a silk dragline that will tether the spider if it falls or misses its target.

[4][22] In preparation, these spiders envelop themselves in sac-like silk shelters hidden underneath rocks and bark.

[2][1][19] As temperatures drop, spiders enter a state of dormancy called diapause, during which development is halted.

[22] In a laboratory study, the lifespan of bold jumpers was a little over a year with females living a couple months longer than males.

[6] After completing their final molts, bold jumpers are fully developed and ready to mate.

[6][22] A male prepares for mating by constructing a small silk mat upon which he releases his sperm from his testes and then draws it into each of his two emboli.

[6][2][21] In this display, he raises his front legs, then flicks his forelegs, and shakes his pedipalps while moving laterally in a zigzag path.

[6][21] Facing her posterior, he then uses his legs to repeatedly rotate her in order to insert his emboli into her two epigynum, releasing his sperm.

[6][22] Reproductive periods are typically in late spring and early summer with the majority of eggs being laid in June and July.

[6][21] She then weaves a cave like webbing over the sac where she will remain during incubation guarding the eggs and adding more silk periodically.

[6][2][21] She does not eat during this time period and will not leave the nest until the second instars emerge from the egg-sac a month later.

[3][4][5] It is believed they were introduced to the arid regions of the southwest United States, surviving in areas where irrigation is practiced.

[5] Bold jumpers prefer temperate climates and can be found in a variety of terrestrial habitats including grasslands, chaparrals, open woodlands, and agricultural fields[3][4][2] The bold jumper is one of the most commonly occurring spider species within its range and can be found living in close proximity to humans.

[24] At night, bold jumpers can be found sheltering in sac-like silk retreats near their hunting grounds.

[14] Bites from bold jumping spiders are rare but may occur if they feel threatened or are mishandled.

[25] On June 11 2021, New Hampshire Governor Chris Sununu signed the HB 318 bill designating Phidippus audax as the state spider.
