In Idaho, P. Bold jumping spiders actively hunt during the daytime, but not at night. These spiders use their keen eyesight to locate prey,then they spring upon the prey and bite it, releasing venom.
They have been observed to have different stalking strategies for different types of prey, approaching flies from a different angle and jumping from a different distance than they do caterpillars. Male and female bold jumpers hunt differently too. Males prefer smaller prey, and spend less time hunting and feeding.
Females prefer larger prey, feed more often, and process prey more to get more food from them. The species may have been absent from the arid southwest prior to modern settlement and irrigation, but have been introduced there by human activity. The species also occurs on the island of Cuba, and has been introduced to the Hawaiian Islands as well. The natural habitats of bold jumping spiders are are grasslands, prairies, and open woodlands. They also occur in agricultural habitat, especially old fields, and are frequently found in backyards and gardens.
The most distinctive features on P. The forward-facing anterior median AM eyes are the largest of all the eyes. When a person looks at the spider, the AM eyes are the ones that look back at that person. To the side of the AM eyes are the smaller anterior lateral AL eyes.
Jumping spiders have very keen eyesight. Eyesight is essential for hunting and courting. These spiders are hairy; cephalothorax and abdomen are black with little, white hairs. The cephalothorax is high, heavy, and convex. The abdomen is distinctly marked. In the middle of the abdomen, there is a large, triangular white spot, with two smaller spots posterior and lateral to the large spotk.
The large spot may be orange in juveniles, and there is some variation in spot patterns within the species, though spots are always white, yellow, or orange. In some individuals there are two oblique lateral stripes. The chelicerae are iridescent green. Males are smaller than females, with more starkly contrasting markings, and more iridescence on the chelicerae.
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 ilk retreat to avoid predators that hunt by touch. The process of copulation begins with a male courting a female.
There is a species-specific courting display, which includes movement of the forelegs, palps and chelicerae. The male lifts certain legs and shows off his colored spots. If the female approaches too rapidly, the male will jump away. In males, a pair of coiled testes lie in the anterior part of the abdomen.
As with nearly all spiders, there is no copulatory organ, and the seminal fluid is transferred to a female by a highly specialized appendage of the palpus during copulation. Females possess ovaries, oviducts, a uterus, a vagina, and one or more spermathecae pouches for the reception and storage of seminal fluid.
All the reproductive organs are located in the abdomen in both males and females. Bold jumpers mature in spring, mate in late spring or early summer, then females produce multiple egg sacs over the summer. A female may produce as many as 6 clutches of eggs, each containing eggs. Average fecundity is about eggs per female. Later clutches tend to be smaller than earlier ones.
Breeding in warmer climates may be more continuous, and adults may survive longer.

Daring jumping spiders are non-aggressive, do not pose any serious danger to humans, but may bite in self-defense. Bites typically result in slight pain and small, itchy bumps on the skin that heals quickly. However, the spiders appearance, their quick movements, and their ability to jump may be unsettling. The most obvious evidence of daring jumping spiders is their appearance during daylight hours when they are most likely to be seen hunting and seeing them in their sheltered locations.
Daring jumping spiders may bite humans in self-defense. Their daytime hunting habits help reduce the number of human bite cases. If bitten, symptoms usually involve slight pain, itching and local reactions such as red bumps that last from days. The daring jumping spider, also known as the bold jumping spider, has a distinctive black or dark-gray hairy abdomen. Spots : Most members of this species have three white spots on their abdomen, but in some species the spots may be red or orange.
Jumping spiders or salticids are known for the spectacular leaps the spiders make pouncing on their prey. Like all spiders, jumping spiders are predators. They eat insects and other spiders. These spiders do not spin webs but make little silken shelters under leaves or bark. There are approximately members of this family worldwide, and they are especially numerous in the tropics.
All species are small, usually less than 15mm long. Jumping spiders do not construct webs, but actively hunt prey during the day, sneaking up and they pouncing on the victim. Many are brightly colored, sometimes with iridescent chelicerae mouthparts. They possess 8 eyes and are known to have the sharpest vision of all spiders, important for hunting ability.
The arrangement of the eyes, four big eyes on the face and four smaller eyes on top of the head, distinguished salticids from other spiders.
