Eastern Green Drake Dun

The Eastern Green Drake Dun, a classic mayfly imitation, replicates the Ephemera guttulata in its graceful dun stage, which emerges prominently in Eastern rivers like the Delaware and Catskills. This fly has roots in traditional American dry fly design and remains a staple among anglers targeting the iconic Green Drake hatch. Designed by early fly tyers who understood the importance of buoyancy and realistic profiles, the Eastern Green Drake Dun continues to thrive as a go-to pattern during late spring and early summer when these large mayflies take center stage. Its broad, upright wings and segmented body create a lifelike silhouette that triggers aggressive rises from trout, especially in slow-moving pools and riffles.

Wing Dipping Presentation: Before casting, wet the fly’s wings lightly to mimic the sheen of a freshly emerged dun. Trout often key in on subtle details, and this added realism can coax wary fish into striking.
