"Master the RS2 Fly: A Versatile Nymph Pattern for Mayfly Hatches"
Darren Crawford What It Is
The RS2 is a subtle yet effective nymph pattern that imitates both the nymph and emerger stages of mayflies.
How It’s Tied
The RS2 is typically tied on a straight or curved nymph hook in sizes 16 to 24. The body consists of fine dubbing in colors like gray, black, or olive, occasionally ribbed with wire or thread for segmentation.
A key feature is its tail, made from microfibbets or hackle fibers, which mimics a mayfly’s split tail. The wing, often crafted from Antron or similar synthetics, can be left long for emergers or trimmed short for nymphs.
The head is simply the tying thread, secured with a whip finish and a drop of head cement for durability.
What It Mimics
The RS2 replicates multiple mayfly stages, particularly nymphs and emergers. Its slender body, split tail, and distinct wing make it adaptable to various mayfly species, matching local hatches with ease.
Where It’s Used
This fly excels in rivers and streams during mayfly hatches. It can be fished alone, in a nymph rig, or as a dropper beneath a dry fly in a dry-dropper setup.
