The Michigan Stone dry fly is a 1950s pattern created by Paul Young who came up with it on Michigan’s Au Sable River. Brought to light in a 1971 article by Chauncy Lively in the Pennsylvanian Angler, this pattern has since largely dropped off the radar. Tied to imitate a yellow stonefly of the region (or the common yellow sally in the mid-Atlantic), this can be an effective summer pattern.
This pattern was tied from instructions in Mike Valla’s “Tying the Founding Flies.”
