They fold their wings flat over their bodies when at rest. Stoneflies are found worldwide, except Antarctica. Plecoptera. As adults, very few stonefly species feed due to their short life span and concentration on mating. Stonefly nymphs develop slowly, taking 1 to 3 years to molt repeatedly before emerging as adults. They move from one stage to the next by shedding their exoskeleton (called 'moulting') over a period of 1-3 years. Stoneflies are so named because the nymphs often live under stones in streams or rivers.

The Common medium stonefly is dark brown with orange patches at the back of its head and in front of its wings. Adult stone flies range from 6 to 50 mm (0.25 to 2.0 inches) long. 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). Carnivorous nymphs have specific adaptations of the mouth for grasping and stabbing prey, while herbivorous nymphs have mouthparts more appropriate for scraping and grinding. Plecoptera.
