This is a slim, unweighted pattern that works good before a hatch and in the initial stages of a blue-wing olive mayfly hatch. Because it is unweighted, it can be hung under a small dry fly or fished deeper behind a heavier nymph like a stonefly. It’s a very popular nymph because these small mayflies are found in trout streams around the world, and hatch fom early spring through late fall.
