Atractelmis is a genus of riffle beetles in the family Elmidae. The genus is monotypic, the sole species being Atractelmis wawona,[3][4] also known as the Wawona riffle beetle.[1][5] It is endemic to the Western United States between California, Oregon, and Idaho.[1][5] The specific name wawona refers to its type locality, Wawona in the Yosemite National Park.[2]
Habitat
[edit]Atractelmis wawona occur in riffles of rapid clear mountain streams at 600–1,500 m (2,000–5,000 ft) above sea level.[1] Adults and larvae occur in the same microhabitats and are typically found in aquatic mosses, particularly Platyhypnidium riparioides.[6] These beetles are easily overlooked but can be locally numerous.[1]
Description
[edit]Adults measure about 2 mm (0.079 in) in length and 0.9 mm (0.035 in) in width. They are shiny black above with four red spots on the elytra.[2] The larvae can grow to 4.8–5 mm (0.19–0.20 in) in length.[6]
