Ameletus validus
combmouthed minnow mayfly
Ameletus validus is a species of mayfly in the family Ameletidae, first described by McDunnough in 1923. It is one of approximately 30 bisexual species recognized in the genus Ameletus across North America. The species occurs in running waters from small headwater streams to large rivers, with documented populations in western North America including Alberta, British Columbia, and the western United States. Taxonomic work has clarified that adult wings are lightly and evenly suffused with brownish-amber, not speckled as previously miskeyed.
