Unlike many other insects, the Mayfly Dun does not land on the water's surface from the air; it appears from beneath it. After the nymph reaches the surface and the shuck splits, the Dun emerges. Before it can take flight, it must sit on the water film to dry its wings. During this period, it is a \"sitting duck\"—completely vulnerable and the primary target for any selective trout.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003e\u003cb data-path-to-node=\"5\" data-index-in-node=\"0\"\u003eAnatomical Precision in Size #12\u003c\/b\u003e The \u003cb data-path-to-node=\"5\" data-index-in-node=\"37\"\u003eMayfly Dun 2 Yellow #12\u003c\/b\u003e is a surgical imitation of this specific moment.
