The Blue Dun is a classic dry fly pattern that is used to imitate the early mayfly hatches. It is a small fly, typically sized 12-18, and is made with a gray body, blue dun wings, and a grizzly hackle.
The Blue Dun is a versatile fly that can be used in a variety of water conditions. It is especially effective in clear, slow-moving streams where the trout feed on the surface.
Here are some tips for fishing the Blue Dun:
• Cast the fly upstream and allow it to drift naturally with the current.
• Use a fine tippet to help the fly float properly.
• Make sure to mend your line regularly to keep the fly in the strike zone.
• Be patient and wait for a good take.
The Blue Dun is a great fly to have in your fly box, especially if you are fishing for trout in the spring or early summer. It is a simple pattern to tie and can be effective in a variety of conditions.
Available in sizes: # 12 - # 18
