     Quote from page 6: "We collected a total of 58 different species in 14 different families of caddisflies (Table 5). Four to 18 species were found in a spring. Several springs had very similar physicochemical characteristics; however, none had identical trichopteran composition. Although Lepidostoma cascadense and Rhyacophila brunnea were restricted to cold springs, they were collected from the most springs (12 each). Lepidostoma rayneri, L. roafi, and L. unicolor were also frequently collected (10, 8, and 7 springs, respectively). Across the region (including all 170 springs surveyed), Hesperophylax designatus was the most commonly encountered caddisfly. It was found in temporary springs, springs impacted by grazing, very cold springs at high elevations, and a few of the warmer (14°C), low-elevation springs. Of the 28 springs intensively studied, it was present in 11."

     Abstract: The timing of life cycles, including growth rates, was determined for eight common species of detritivorous insects in a second-order stream in southwestern British Columbia, Canada. Six of the species (Zapada cinctipes, Z. haysi, Malenka californica, M. cornuta, Capnia sp., and Lepidostoma roafi) had simple, univoltine life cycles. The leuctrid stonefly Despaxia augusta has a 2-year life cycle, with an apparent egg diapause of about 6 months. The chironomid Brillia retifinis produced at least three generations per year. The major growth periods for the set of species considered here span the entire year. Adults of several species exhibited seasonal declines in size at emergence, but one species had larger adults as the emergence period proceeded. Closely related taxa had more similar life cycle timing than more distantly related species suggesting a degree of phylogenetic constraint in phenology of their life cycles. The influence of the timing of leaf drop on timing of life cycles for these animals does not fit with proposed scenarios based on fast and slow leaf processing rates.
