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 ...
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 .
Salticidae male anterior and dorsal aspects, showing positions of eyes A regal jumper staying near its shelter on a thistle. It attempts to capture a small winged insect.

A male Eresus sandaliatus. Sexual selection in spiders shows how sexual selection explains the evolution of phenotypic traits in spiders.Male spiders have many complex courtship rituals and have to avoid being eaten by the females, with the males of most species surviving only a few matings and consequently having short life-spans.
When a male and an unmated female meet, it takes about 30–60 seconds of courtship until mating occurs. Males have been observed to initially court females laden with eggs, females from different Phidippus species, or even simples models out of clay with a pair of wires as appendages. Previously mated females may retreat, or attack the male as ...
If a female that has mated already finds another larger male, she will often mate again with the larger male. The average clutch is 135 eggs. Unlike most of the genus Phidippus, P. clarus females die after one brood has left the nest. P. clarus is parasitized by the wasp Aporinellus completus and by mermithid nematodes.
