The RS2 is a delicate yet highly effective fly pattern that perfectly imitates the nymph and emerger stages of mayflies. Its subtle design makes it a must-have for anglers targeting selective trout.
Tying the RS2
This versatile fly is tied on a straight or curved nymph hook (sizes 16–24) with a slender body of fine dubbing in colors like gray, black, or olive. A thin wire or thread rib adds segmentation for realism.
Key features include:
- Split-tail fibers (microfibbets or hackle) to mimic a mayfly’s tail.
- Antron wing—left long for emergers or trimmed short for nymphs.
- Minimalist head—secured with thread and head cement for durability.
What It Imitates
The RS2 excels at replicating multiple mayfly life stages, from nymphs to emergers. Its slim profile, segmented body, and lifelike tail make it adaptable to various mayfly species, ensuring success on diverse waters.
Best Fishing Tactics
Ideal for rivers and streams during mayfly hatches, the RS2 can be fished:
- As a standalone nymph
- In a tandem nymph rig
- Beneath a dry fly (dry-dropper setup)
A proven trout-catcher, the RS2 is a go-to pattern for fooling even the most wary fish.
