Nectopsyche diarina
White Miller Caddisfly
Nectopsyche diarina is a species of caddisfly in the family Leptoceridae, first described by Ross in 1944. The genus Nectopsyche is commonly referred to as "white millers," a name derived from the pale coloration of adults. Like other members of this genus, N. diarina is attracted to ultraviolet light, making it observable during nocturnal blacklight surveys. The species occurs in North America within the Nearctic region.
