Moss Mayfly Grey
This is one of a trio of authentic Dennis Moss Mayfly patterns in my collection. It is extremely popular in the West of Ireland. Dennis says of it. "This fly imitates the last phase of the Mayfly cycle-the adult spinner or spent phase. I have huge confidence in this and the Ginger mayfly,and whereas the Ginger is the fly for the duns,the Grey is the pattern for the gnat rise. Towards the latter half of the Mayfly hatch,and for the evening fall of spent fly,the Grey comes into its own.It is a big trout fly with a long pedigree. I have yet to fish a lough in Ireland where the trout refuse it."(Quote from "Trout and Salmon- The Essential Guide to Irish Lough Fishing" by Dennis Moss.)
