Similar to the household lubricant from which this pattern derives its name, the WD-40 works anytime and everywhere! The profile of this fly and the various colors in which it is available make it one of the most versatile patterns, able to match a host of midge, chironomid, and mayfly species. The addition of the loopwing to this particular flavor of WD-40 is intended to imitate the emerging wing of a mayfly or midge, and can be fished to great effect as a dropper just below the surface of the water or dead drifted along the bottom of the river.
