A Versatile Mayfly Nymph Imitation for Diverse Conditions
The Blue Dun Nymph is a classic pattern designed to replicate the nymphal stage of various mayflies, particularly those with bluish or grayish hues. Its slender, dark body combined with subtle hackle fibers effectively mimics the natural appearance of mayfly nymphs found in both rivers and streams. This nymph is especially effective during mayfly hatches, making it a valuable addition to any angler's fly box.
