Adult female P. regius measure 15 mm (0.59 in) long on average, but can range between 7–22 mm (0.28–0.87 in) long. They may exhibit white or orange markings on the opisthosoma similar to the white markings seen in males, but the rest of the body is largely covered with scales which may be brown, orange, tan, gray, or a combination of those ...
The accuracy of their jumps is mediated by their well-developed visual system and the ability to quickly process visual information to tailor each jump. [28] [29] When a jumping spider moves from place to place, and especially just before it jumps, it tethers a filament of silk (or 'dragline') to whatever it is standing on.
Phidippus is a genus in the family Salticidae (jumping spiders). [1] Some of the largest jumping spiders inhabit this genus, and many species are characterized by their brilliant, iridescent green chelicerae. Phidippus is distributed almost exclusively in North America, with the exception of two exported species (Phidippus audax and Phidippus ...
The jumping spider Phidippus audax. The basal parts of the chelicerae are the two iridescent green mouthparts. The basal parts of the chelicerae are the two iridescent green mouthparts. The chelicerae ( / k ə ˈ l ɪ s ər iː / ) are the mouthparts of the subphylum Chelicerata , an arthropod group that includes arachnids , horseshoe crabs ...
[18] [20] Spiderlings are known to survive without food while travelling in air currents of jet streams for 25 days or longer. [5] Some mites and some caterpillars also use silk to disperse through the air. [21] [22] A close association has been found between ballooning behaviors and the ability for a species of spiders to survive afloat on water.
Phidippus californicus is a species of jumping spider. It is found in the southwestern United States ( California , Arizona , New Mexico , Nevada , Texas , Utah ) and northern Mexico ( Baja California peninsula , and Sonora ).
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".
