Dark Cahill Wet Fly

The fly pattern typically features a dark color scheme, with variations in shades of brown or black. The use of dark colors helps mimic the natural appearance of mayfly nymphs and emergers.

The fly is tied on a wet fly hook. The hook size can be adjusted based on the specific water conditions and the size of the insects you are trying to imitate.

The fly starts with a tail made of dark brown or black hackle fibers. These tail fibers are typically sparse and about the same length as the hook shank.

The Dark Cahill Wet Fly is a versatile pattern that can be fished in various ways.

It can be presented as a nymph by allowing it to sink and drift naturally in the water. Alternatively, it can be swung across the current to imitate an emerging insect.

The fly can be effective during mayfly hatches or when trout are actively feeding on nymphs in the water column.

Usually available in the following hook sizes: 10 | 12 | 14 | 16 | 18
