White Miller Caddisflies, White Millers
Nectopsyche is a genus of caddisflies in the family Leptoceridae, commonly known as white millers. The genus contains at least 70 described species distributed across the Americas, with records from North America through the tropical Andes. Species occupy diverse freshwater habitats ranging from lentic (still-water) environments to lotic (flowing) highland streams. Several species have been studied as bioindicators of aquatic pollution due to their sensitivity to pesticides and heavy metals.
