Phidippus regius, commonly known as the regal jumper,[2] is a species of jumping spider found in parts of the United States and the Caribbean.

In southern populations, juvenile females may develop scales as early as the third instar, while males are black and white throughout their life cycle.

[3] 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.

Females of the species lay their eggs under the bark of trees, or in secluded spots in wooden structures such as barns.

[4] P. regius occurs in the southeastern United States, Bahamas, Bermuda, Greater Antilles, and has been introduced to Easter Island.
