Phidippus princeps
Grayish Jumping Spider
Phidippus princeps is a jumping spider species in the family Salticidae, found in Canada and the eastern United States. It is a visually oriented predator with exceptional eyesight—exceeding that of dragonflies by a factor of ten. The species exhibits pronounced sexual dimorphism, with males displaying striking red, black, and white coloration with metallic blue chelicerae, while females are larger with more somber coloration, a rounded abdomen, and smaller carapace. Research has demonstrated that P. princeps movement is strongly directed by vegetated corridors, which facilitate interpatch movement in fragmented habitats.
