Taraperla stonefly nymphs are relatively small, with a rosette of anal gills between the cerci (“tails”). The posterior edges of the thoracic segments are extended to form lobes or spines (depending on the species).
Taraperla nymphs can be found in cold water stony streams, both above and below the water surface.
They are thought to be “collector-gatherers”, feeding on a range of organic matter accumulating on stream beds.
Taraperla nymphs are usually found in streams with good water quality, though they are rarely found in abundance. They have tolerance values of 7 (hard bottom sites) and 8.3 (soft bottom sites).
