Fishing Tips

Season

The Johnny Flash can be used year-round, but it's particularly effective in the colder months when midges are one of the few insects still hatching.

Presentation

Fish it in the surface film or just below, either on its own or as part of a multi-fly rig.

When to Use

Use the Johnny Flash when you see trout feeding on emerging midges, often indicated by splashy, aggressive rises.

Water Type

This fly works well in both stillwater and moving water.

Rigging Suggestions

Try fishing it behind a dry fly or larger nymph to get it down in the water column.

Visibility & Floatation

The Johnny Flash is not designed to float, but it is highly visible thanks to its flashy body. The peacock herl thorax adds a touch of natural iridescence that can trigger strikes.
