On the water
Understand it. Then fish it.
The river, depth, insects, and fish behavior still decide the final presentation. These are reviewed starting points—not a claim about what is happening today.
How to fish it
- Dead-drift flat in the film.
- Track it with a nearby visible dry.
Mistakes to avoid
- Fishing it like an upright dun.
- Assuming every mayfly spinner shares one body color.
Variant control
Small changes matter.
Three reviewed technical illustrations show the identifying profile, construction, and fishing orientation. They are schematic field-guide aids, not photographs.
