    The Larva and Pupa of Cochliopsyche vazquezae (Trichoptera:Helicopsychidae)
    (University of Chicago Press, 1988) Monson, Margot P.; Holzenthal, Ralph W.; Ahlstrand, Gilbert G.
    The larva and pupa of Cochliopsyche vazquezae Flint are described, representing the first complete description of these stages for the genus. The larva is characterized by the possession of a prominent patch of setae on the anterolateral margin of the head capsule and by a marked concavity in the postgenal region, giving a "hollowed out" appearance to the posterolateral aspect of the head. Pupae bear a similar group of setae below and mesad of the eye. Notes on the biology and habitat of C. vazquezae in Costa Rica are given.
