Fishing Tips

Season

Spring through Fall

Presentation

Fish this pattern using a traditional Czech nymphing technique. Keep the rod tip high and the line tight, allowing the current to naturally swing the fly downstream.

When to Use

This pattern works exceptionally well during a mayfly hatch, but don't be afraid to use it as a searching pattern when no hatch is present.

Water Type

It is ideal for moving water such as streams and rivers. It can also be used in stillwater, but is most effective in moving water.

Rigging Suggestions

Use a heavier nymph as an anchor and tie the Czech Catnip as a dropper. This allows the fly to drift naturally in the current.

Visibility & Floatation

The Czech Catnip is a sinking fly. The gold bead head helps it get down quickly in the water column and adds a bit of flash to attract fish. The Solarez Bone Dry UV resin coating adds shine and durability to the fly.
