Black Beauty – Big Y Fly Co.
Midges bring fish to the surface 12 months out of the year. American Angler estimates midges account for 22% of trout’s diet, by far the single most important single food source.
Despite all this, many anglers ignore flies below size 16, so fish aren’t used to seeing artificial flies this size, increasing their likelihood to strike.
Midges are a great winter food source. This pattern is an excellent imitation with translucent peacock and lots of sparkle to attract attention.
A Colorado favorite, ideal for emerger and pupae presentations.

Carolyn Knox –
Used this fly during a winter trout trip in Colorado. The translucent body and sparkle stood out in the water. Fish took it on the first cast, especially during emerger stage. A solid choice for cold season fishing.
Jan Vance –
Felt like a natural midge when fished in the early morning. The sparkle caught the light well and trout were responsive. Works well in low visibility conditions.
Amy Fraser –
Great imitation of midge pupae. I’ve used it in several streams and it consistently gets strikes. The size is perfect for trout that aren’t used to small flies.
