Below are Giant Salmonflies
They are a Stonefly and require flowing water to live, and the highest populations are found in cool oxygenated streams.
These Stonefly nymphs are found in rocky riffles and runs with fast to moderate currents. Large, fast flowing streams generally support the highest population of nymphs, with their numbers decreasing as the streams get smaller and colder.
Whenever these nymphs are found in large numbers, trout and anglers are always aware of them. The different age classes of nymphs in a stream insure that enough large insects will be found drifting in the currents on most days to keep trout interested.
Mature nymphs that migrated into the shallows during the late afternoon and evening begin crawling out of the water at dusk. This mass departure continues into late night or early morning hours. After leaving the water, the nymphs crawl a short distance and cling to streamside foilage and rocks.
foilage will be crawling with adult Salmonflies and anglers. Trout often take a day or two to realize these large bugs are food, but after they get the message, some exciting dry fly fishing follows.
