The Sparkle Dun Baetis is a delicate and highly effective dry fly designed to imitate the Baetis mayfly in its emerging stage. Featuring a trailing shuck of sparkle material, this fly mimics the natural appearance of an emerging mayfly, making it particularly effective during Baetis hatches. The low-riding profile and realistic color scheme entice selective trout, while the sparkle adds a subtle flash that can draw attention in low light or slightly murky conditions.
