Habronattus pyrrithrix
Habronattus pyrrithrix is a small jumping spider in the family Salticidae, native to the southwestern United States and western Mexico. Males display striking sexual dimorphism with bright red facial coloration and green legs used in complex multimodal courtship displays, while females are larger with cryptic brown and grey coloration. The species exhibits trichromatic vision and uses color cues when foraging, actively avoiding red and yellow prey that may signal chemical defenses. Males employ visual, vibratory, and seismic signals during courtship to reduce female aggression and cannibalism risk.
