Pseudostenophylax edwardsi

(Banks, 1920)

Edwards's northern caddisfly, limnéphile d'Edwards

Pseudostenophylax edwardsi is a of caddisfly in the Limnephilidae, native to western North America. It inhabits montane seepage areas, both temporary and permanent. The species is in the field but has been observed to complete two per year under laboratory conditions at 15°C. Females are capable of mating and ovipositing in laboratory settings, making this species a candidate for continuous culture and potential use in and behavioral studies.

Habitat

Montane areas with temporary and permanent seepage zones. Larvae and pupae develop in seepage .

Distribution

Western North America: British Columbia (Canada); California, Idaho, and Oregon (United States).

Life Cycle

in natural field conditions; capable of two per year at 15°C in laboratory culture. Final-instar larvae enter under short-day conditions. Complete development from to pupa has been achieved in mass culture and individual rearing.

Behavior

Females will mate and oviposit in laboratory conditions, suggesting potential for continuous culture methods.

Human Relevance

Identified as a promising laboratory test organism for procedures and behavioral studies due to ease of rearing and ability to complete full in captivity.
