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 close to cover.
- Use a visible indicator spot only as a labeled feature, not a different insect.
Mistakes to avoid
- Confusing beetles with two-lobed ants.
- Assuming every black foam fly is a beetle.
Variant control
Small changes matter.
This first family destination uses a reviewed comparison map. Each named representative remains labeled, and the family is not presented as one exact fly.
