Dry FliesHi-Vis Callibaetis Spinner
The Hi-Vis Callibaetis Spinner is a stillwater spinner pattern featuring a UV orange post for exceptional visibility during evening spinner falls. The white EP fiber wings lie flat to imitate the splayed wings of a spent mayfly, while the white mayfly tails and tan dubbing body complete the Callibaetis spinner profile. This pattern solves the visibility problem inherent in traditional spinner patterns.

Overview
The Hi-Vis Callibaetis Spinner was developed at Blue Ribbon Flies to solve the visibility challenges of spinner fishing. The UV orange post is visible to the angler but positioned so fish see only the natural spinner silhouette from below. This innovation makes tracking the fly possible during low-light conditions when spinner falls typically occur.

Fishing Tips
Season
Most effective from June through August during Callibaetis spinner falls. Peak activity occurs in the evening hours when spinners return to the water to lay eggs and die.
Presentation
Cast ahead of cruising fish and let the fly sit motionless. The hi-vis post allows tracking the fly while waiting for subtle takes. Strike when the post disappears or the fly moves unnaturally.
When to Use
Best during evening spinner falls on stillwater when fish make subtle sipping rises. The hi-vis post makes this pattern ideal when light conditions make tracking standard spinners impossible.
Water Type
Designed specifically for lakes, ponds, and reservoirs with healthy Callibaetis populations. Particularly effective on high mountain lakes and beaver ponds during spinner falls.
Rigging Suggestions
Fish on 12-15 foot leader with 5X-6X tippet. Long leaders are essential for stillwater presentations. The hi-vis post eliminates the need for indicator patterns.
Visibility & Floatation
Excellent visibility from the UV orange post while maintaining a natural appearance to fish. White EP wings provide good floatation. The post position minimizes fish detection.
