- Colors reviewed
- dark brown nymph, orange-brown adult, mottled wing

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
- Fish nymphs before and during migration; use large dries near banks and broken water once adults matter.
Mistakes to avoid
- Assuming all large orange dries are salmonflies.
- Treating a hatch prediction as a current observation.
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.
