Phidippus johnsoni – Red Back Jumping Spider
Few jumping spiders command attention quite like Phidippus johnsoni. The Red Back Jumping Spider is one of North America's most visually striking Phidippus, sporting a vivid crimson abdomen against a jet-black cephalothorax — a color combination that makes this species instantly recognizable and endlessly photogenic. Add in the signature oversized eyes and bold, interactive personality of the genus, and you have one of the most compelling display spiders available in the hobby.
