On the water

Know when and how to fish it.

Use these tips as a starting point. The river, depth, insects, and fish behavior still decide the final presentation.

01

When to use it

  • In vegetated trout water during terrestrial activity.
  • As a bright subsurface attractor.
02

How to fish it

  • Dead-drift below or close to vegetation.
  • Use a labeled bead-head form when extra depth is required.
03

Mistakes to avoid

  • Showing a bead-head version as the only form.
  • Claiming the pattern precisely imitates one species.

Common variations

Small changes can make a different fly.

Three reviewed technical illustrations show the identifying profile, construction, and fishing orientation. They are schematic field-guide aids, not photographs.
