Pycnopsyche luculenta
northern caddisfly
Pycnopsyche luculenta is a northern caddisfly in the family Limnephilidae, native to North America. Larvae inhabit allochthonous organic materials and show distinct habitat preferences and case material choices that differ from congeneric species. The species exhibits temporally segregated adult flight behavior, with male peak arrival times at light differing from sympatric P. gentilis. Research has documented larval dispersion patterns using unique tagging methods.
