| features: | The Nemouridae are a family of stoneflies, with more than 600 described species with a mainly Holarctic distribution.[1] Members of this family are commonly known as spring stoneflies or brown stoneflies. Fly fishermen often refer to these insects as tiny winter blacks.
Although these insects use a wide range of flowing-water habitats, they tend to be most prevalent in smaller streams. The nymphs are distinctive, being broad-bodied and bristly with divergent wing pads.
