The Blue Dun Midge is a subtle, highly effective pattern designed to imitate midge adults and emergers during surface feeding events. With its slim slate-gray body and delicate profile, this fly excels in clear water and calm conditions where trout are keyed in on small, emerging insects. Its a must-have pattern for early mornings, late afternoons, and cold-weather fishing when midges dominate the hatch scene.

Tied with fine materials for a natural appearance, the Blue Dun Midge sits just in or below the surface film, making it perfect for imitating stillborn or emerging midges that trout often target. The muted blue-gray coloration closely matches natural midge hues and offers excellent visibility to fish without spooking them.

To fish the Blue Dun Midge effectively, use it on a long, light leader and present it with a dead drift to rising trout. In slow water or spring creeks, its especially effective when fish are sipping midges in the film. It can be fished solo or trailed behind a slightly larger dry fly for added visibility and strike detection.
