Habronattus decorus
beautiful ornamented jumping spider
Habronattus decorus is a small jumping spider in the family Salticidae, first described by John Blackwall in 1846. Males display distinctive reddish abdominal patches covered with iridescent rose to bluish scales, while females lack this ornamentation and instead show dark brown stripes on a yellowish background. The species occurs across northern North America, with males measuring approximately 5 mm and females slightly larger at about 6.5 mm. Like other Habronattus species, males perform elaborate multimodal courtship displays combining visual signals with vibratory drumming.
