About Habronattus americanus (Keyserling, 1885)
Female Habronattus americanus spiders are brown and gray, with only a small range of color variation. Male individuals are black on their upper body; the male's pedipalp and parts of its legs are red. Males use this red color to attract females during courtship displays. This species lives in western North America, with its known range extending from British Columbia, Canada in the north to California, United States in the south. Its range stretches from the Pacific coast inland to Alberta and Montana. The species may occur further beyond this area, but current understanding of its distribution is only based on confirmed reported sightings.
