On the water
Narrow the family.
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
- Choose stage from water position and rise form; fish spinners flat in the film.
Mistakes to avoid
- Calling a dun a Coffin Fly spinner.
- Assuming all drakes share color or behavior.
Variant control
Small changes matter.
This stage comparison keeps materially different forms labeled. It is a family guide, not a claim that one fly represents every stage or local species.
