Callibaetis Sparkle Dun
The Callibaetis Sparkle Dun is the essential pattern for matching Western lake hatches, where Callibaetis mayflies produce prolific afternoon hatches from spring through fall on stillwaters and slow spring creeks. The trailing Antron shuck imitates the emergent dun still attached to its nymphal shuck — the moment lake-resident trout target most aggressively. Fish it on a long, light tippet with no movement on calm glassy lake surfaces.

Materials

- tail: Amber Antron yarn, trailing shuck
- body: Gray or tan-olive dubbing
- wing: Coastal deer hair, fanned (comparadun style)
Tying steps
- Mount a size 14–16 hook; tie in a sparse amber Antron shuck at the bend.
- Dub a slim gray or tan-olive body to the 2/3 mark.
- Stack a small bunch of coastal deer hair; fan into a comparadun half-circle wing.
- Post-wrap to lock the wing upright.
- Trim the deer hair butts to form a head.
- Whip finish and apply UV resin to the wing base.
- Apply a micro-drop of head cement to the thread head only; never apply cement near the deer hair wing.
- Inspect the trailing Z-Lon shuck — it should hang below the surface film, not float on top.
- Check the trailing Z-Lon shuck is properly attached below the hook bend and hangs at a slight downward angle, not projecting straight back or upward.
