Zapada cinctipes (Banks) 1897
Common Forestfly, Winter Black stonefly, Little Sepia Stonefly
Updated 27 Apr 2016
Common in streams, seeps, wetlands, alpine ponds and large rivers. Baumann et al (1977) mentioned this stonefly has excellent dispersal behavior.
East River, Copper Creek, Blue Creek, Cimmarron River, East Elk Creek, Red Creek. Often found with Zapada haysi. Common in northern Colorado.
The genus Zapada was previously named Nemoura. Older publications may refer to this species as Nemoura cinctipes.

Quote from page 43: "This species is common throughout western North America. It has been collected in all of the Rocky Mountain States except Arizona. This species usually emerges from February to August, but has been collected in all months of the year in some localities." They mention Zapada cinctipes is present in Gunnison County, Colorado.

The authors studied the acute short term tolerance of aquatic insects to low oxygen. They used the 96 hour Median Tolerance Limit. They discuss Zapada cinctipes as Nemoura cinctipes. The TLm96 for Z. cinctipes was 3.3mg/l and 29% oxygen saturation.

Quoted from page 392: It is difficult to imagine a stonefly species that can occur in so many different lotic and even lentic habitats. Although it is most common in small streams, it occurs in seeps, wetlands, alpine ponds and large rivers. Zapada cinctipes has been collected from several localities in Colorado nearly every month.

Discussed as Nemoura cinctipes. Found from about 7000 to 8400 feet elevation in their study of the upper Gunnison Drainge in the early 1960s, they felt this was a stenothermic group limited to lower altitudes.

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.

Abstract: " Winter stoneflies (Zapada oregonensis, Z. cinctipes and Capnia confusa) used detritus as a nymphal food almost exclusively and dominated the shredder biomass in a third-order mountain stream in Colorado. Laboratory feeding trials showed that ingestion rates and fecal production were temperature-dependent, although not greatly different between aspen or alder leaf discs. Assimilation efficiency (AE) was not temperature-dependent. Higher AE values for alder indicate that it is superior to aspen as a food source. High consumption rates (ca. 30% of body weight/day) by the shredders, even at low temperatures, would result in the conversion of considerable quantities of leaf litter to finer particles. However, size fraction analysis of egested material indicated that particle size reduction by shredder processing only partially explains detrital composition in a stream dominated by fine-particle feeding detritivores."
