Description

Beadhead Isonychia Nymph

The Beadhead Isonychia Nymph is a popular fly pattern used by fly fishermen to imitate the nymph stage of the Isonychia mayfly. The Isonychia mayfly is commonly found in rivers and streams throughout North America and is an important food source for trout and other fish.

The BH Isonychia Nymph typically features a dark brown or black body, a ribbing of copper wire, a beadhead, and a tail made of brown or black fibers. The fly is typically fished using a nymphing technique, where the fly is cast upstream and allowed to drift naturally along the bottom of the river or stream.

The Beadhead Isonychia Nymph is an effective fly pattern throughout the year, but is particularly effective in the late summer and early fall when the Isonychia mayfly is most active.

Usually available in the following hook sizes: 8 | 10 | 12 | 14
