Blue Dun Midge

The Blue Dun Midge is a subtle, high-confidence pattern designed to imitate tiny midge pupae and emergers—one of the most important food sources for trout in cold, clear water. Its slim blue-grey body and fine ribbing create the perfect silhouette in the surface film, making it deadly during winter and early-spring midge hatches when trout are feeding delicately. The understated color profile blends naturally with the hatch and excels when fish refuse flashier patterns. This fly is ideal for technical tailwaters and spring creeks where trout key in on micro-insects. Its neutral tones and realistic shape make it a go-to dropper pattern, a great second fly in a tandem rig, or a deadly option fished alone on light tippet during calm surface activity. Best for: Trout feeding on tiny midge pupae or emergers Clear, pressured tailwaters and spring creeks Dropper rigs, film presentations, or winter nymphing 📌 Pro Tip: Pair the Blue Dun Midge with a high-vis dry fly during hatch windows.
