Adult male ''P. regius'' measure long on average, but can range between long. The first pair of legs, which are disproportionately larger in large males, have an alternating black and white fringe. The opisthosoma
The opisthosoma is the posterior part of the body in some arthropods, behind the prosoma ( cephalothorax). It is a distinctive feature of the subphylum Chelicerata (arachnids, horseshoe crabs and others). Although it is similar in most respects ...
is black with several white markings on the dorsum - a basal band, a central triangular spot, and two posterior oval spots. The chelicerae

are large and iridescent green-blue-violet in color, with a tubercle on each.[
Adult female ''P. regius'' measure long on average, but can range between 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 colors. The chelicerae are iridescent green or red-violet in color, but lack the tubercles found on the chelicerae of males. Females have several tufts of ]setae

Although Phidippus regius is considered minimally harmful to humans, there have been documented cases where the bite caused severe pain, similar to a bee sting, as well as prolonged swelling lasting up to three months. This reaction is likely due to individual sensitivity or localized tissue inflammation.

Habitat
''P. regius'' is most commonly found in relatively open areas, such as fields and light woodland, with adults usually preferring trees or the walls of buildings as hunting grounds. They build silken nests at night in which to sleep, often in palm fronds or similar areas. Females of the species lay their eggs under the bark of trees, or in secluded spots in wooden structures such as barns.
