Appearance

Black body with orange coloration on the middle section (). As with other Habronattus , likely small in size (most species in this range from 3-7 millimeters in body length). The genus is characterized by compact, robust bodies typical of jumping spiders, with large that provide excellent vision.

Habitat

Ground-dwelling, found in areas of scattered vegetation where it prowls on stones or amid leaf litter. Typical Habronattus includes prairies, grasslands, and open areas with sparse ground cover.

Distribution

United States. Records indicate presence in North America, specifically within the USA. The Habronattus shows highest diversity in the southwestern United States.

Behavior

As a member of the Habronattus, likely exhibits complex multimodal courtship involving both visual displays and vibratory signals (drumming/tapping). Males of the genus characteristically use modified third legs in , bending them to maximize visibility of knee joints to females. Hunting behavior typical of salticids: active pursuit of prey using keen eyesight rather than web-building.

Ecological Role

of small insects and other arthropods. As a jumping spider, contributes to regulation of insect in ground-level .
