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
- Dead-drift nymphs near bottom; present adult patterns tight to likely banks and seams.
Mistakes to avoid
- Publishing one calendar date for every river.
- Using an adult dry for a nymph recommendation.
Variant control
Small changes matter.
This comparison separates materially different insect, stage, or pattern forms. It is a family guide, not a claim that one fly represents every local species.
