The nymphs of many species are 'opportunistic feeders', meaning that they feed on what is around, while others may select for specific prey species or sizes. Soil & Water Conservation Society of Metro Halifax (2006). Stoneflies. Adults can be collected near porch lights to which they are drawn. Stonefly and mayfly nymphs look much alike and are often confused. The ecological requirements of nymphs and the reduced flight capacity of adults are the main factors responsible for their high endemicity (Fochetti and Tierno de Figueroa, 2008). Temperate species of stoneflies may have nymphs that overwinter, and continue to grow even when water temperatures drop to 0°C. This mechanism enable caddisfly larvae to live in waters too low in oxygen content to support stonefly and mayfly larvae. It studies the description of the Stonefly and the lifecycle of the Stonefly.

Cranefly larvae are rather large, from one to three inches Nymphs live along the bottom of aquatic habitats (benthic dwelling). Approximately 1600 species of stoneflies are found throughout the world, and more than 450 species occur in North America. Nymphs have wing pads-saclike growths containing the developing wings-and two long tail filaments. Stonefly nymphs play an important role in freshwater systems, serving as a food source for various fish and invertebrate species. Stoneflies are so named because the nymphs often live under stones in streams or rivers. The female may also submerge herself into the water and deposit the eggs on the bottom of the stream. They can also be found on most larger islands, with the exceptions of Hawaii, Cuba, Fiji, and New Caledonia. Generally, these predatory Stonefly nymphs feed on other aquatic invertebrates. They go from egg, to nymph and straight to adult, without the pupal or dun stages. To lay the eggs, the female flies over the water and may dip her abdomen in the water, releasing the eggs, or may drop the eggs directly into the water from the air.

In cold climates a few species even fly in midwinter when snow is on the ground. In most species, the adult stage feeds but dies shortly after mating. Many species require only 2-3 weeks for hatching, while some larger forms require several months. Those that do feed on algae and lichens, nectar, or pollen. Adults are terrestrial and can be found near aquatic habitats with running water, resting on rocks, debris, and vegetation.

They prefer streams with a significant current, on rocky, stony, or gravel substrate, although there are some species that live in sandy areas. They may also be found in cold ponds and lakes in the north and at higher latitudes. In some locations enormous numbers of adult stoneflies may occur at about the same time each year. Stoneflies have incomplete metamorphosis: they gradually develop into adults after about two to three dozen nymphal instars, or growth stages. Stonefly nymphs have varying feeding preferences, dependent on their life stage, species and avaliable food sources. Scientific classification: Stoneflies make up the order Plecoptera.

Most stonefly cannot tolerate any pollution and need very clean water to survive. The wings have many veins, and the hind wing is broad at the base and fanlike. Spent stoneflies often struggle and sink below the surface film; perhaps that is why some of the most effective imitations are tied in a spidery wet fly style. Other species have gill tufts protruding from various parts of the body. To make things easy StoneFly’s Ceph storage is now bundled with block, object and file storage in one centrally managed unified platform. Learn About This Fly.

Females of some species can deposit over 1000 eggs. Adult stoneflies have two pair of membranous wings that fold over the back when at rest. As adults, very few stonefly species feed due to their short life span and concentration on mating. They fold their wings flat over their bodies when at rest. Stonefly larvae live in cold, gravelly or mucky stream bottoms and are a key food for trout and other fish. Tree of Life Web Project (2010).
