May is an optimum time for Stoneflies in Central Oregon rivers and elsewhere as the rivers warm. This is a simple pattern…like an enlarged nymph pattern.
A size 8-10, 3xlong hook, goose biot tail, copper wire ribbing, black fur/synthetic dubbed abdomen/thorax. The ‘backstop’ from tail, up over the abdomen and thorax is turkey feather. The legs in front is a few wraps of black hackle fiber. A simple, yet productive tie. This pattern can be weighted with wraps of ‘lead’ wire or left unweighted and weight attached to the tippet. Blacks, brown, dark yellow/rust colors for the stonefly contingent that emerges/crawls out starting now into Summer.
