[2] Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and ...
Phidippus audax are commonly referred to as "bold jumping spiders" or "bold jumpers". [8] The species name, audax, is a Latin adjective meaning "audacious" or "bold". [8] This name was first used to describe the species by French arachnologist Nicholas Marcellus Hentz, who described the spider as being, "very bold, often jumping on the hand which threatens it".

These large jumping spiders are found on bushes such as the sagebrush (Artemisia tridentata), the rabbitbrush (Chrysothamnus nauseosus), and the Four-winged Saltbrush (Atriplex canescens). P. californicus prefers bushes that grow on slopes with thin, stony soils, and appears to avoid conifers and moist habitats (e.g., the proximity of ...
Adult male P. regius measure 12 mm (0.47 in) long on average, but can range between 6–18 mm (0.24–0.71 in) long. The first pair of legs, which are disproportionately larger in large males, have an alternating black and white fringe.
Size. Like all Jumping Spiders Pelegrina aeneola is sexually dimorphic. Females are 5.5 millimeters while the slightly smaller males are 5 millimeters long. [6]
The magnolia green jumper is small for a jumping spider, with adult females measuring 7-8mm and adult males 5-6mm. [3] Most specimens appear as a pale, partially translucent green (from which they derive a part of their taxonomic and common names) with a small fringe of scales which may appear red, orange, yellow or white on the crown of the head, framing the eyes.

Phidippus clarus is found in old fields throughout most of the United States and southern Canada. [2]: 61 [6] It has also been recorded from western Mexico.[2]: 61 It lives among flowers, often sharing habitats with the small to medium-sized crab spider Misumena vatia, [7]: 4 [7]: 278 which waits for prey.
