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
- Retrieve or suspend nymphs appropriately; use emergers and dries as insects move to the film.
Mistakes to avoid
- Assuming river-style dead drifts cover every stage.
- Presenting a parachute adult as the lifecycle.
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.
