Fountains of Youth – Classic trout flies that have withstood the test of time … flies that remain “forever young”

by Rusty Dunn

The popularity of many fly-tying materials changes with time. New materials appear in the market, are popular for a few years or maybe even a few decades, but even­tually fade from use, being replaced by newer (usually better) materials. The old materials disap­pear into obscu­rity, only to be encountered later as amusing odd­ities. Try to find flies today tied of hog’s wool, sea swal­low, stoat tail, kapok, hedge­hog belly, wren tail, or mon­key fur. It won’t be easy. Each of these materials had its fifteen minutes of fame, but they are now oddball rel­ics found mostly in antique fly boxes and long-forgotten angling books. On the other hand, some tying materials have graced our hooks for cen­tu­ries. They are the furs, feath­ers, fibers, and flash whose ability to fool trout has never been surpassed. Such mater­ials that have sur­vived the most demand­ing test of all … the test of time.

Peacock herl is one such exceptional material, and for good reason. It glitters, glistens, and sparkles in the sun. It is translucent and beautifully iridescent, shifting colors from emerald green to olive to bronze as lighting condi­tions change. The soft feather barbules quiver in the cur­rents, imitating downy external gills of many juvenile aquatic insects. Pea­cock herl is quite magical when drifted before trout. They simply love it, and pea­cock herl has main­tained a place of promi­nence in fly-tyers’ bag of tricks for over 500 years.

Use of peacock herl in artificial flies dates to the very be­ginnings of recorded fly angling. Dame Juliana Bern­ers, Prior­ess of Sopwell, authored the very first book of fish­ing with artificial flies. Her essay A Treatise of Fish­ing with an Angle (1496) described materials of twelve artificial flies, two of which, the Black Leaper and the Shell Fly, are believed to have been cad­dis­ imitations. Both have underbodies of wool that are “lapped about with the herle of ye pecock tayle”.

Pea­cock herls are barbs of the beautiful and shock­­ingly long tail feathers of male peafowl. Peacock was firmly estab­lished as a favorite tying material by the era of Walton & Cotton (The Complete Angler, 1676) and has remained so ever since. The most famous of all pea­cock-bodied flies is probably Tom Bos­worth’s Coach­man wet fly of the early 1800s. Descendants of the Coachman, such as the Pass Lake Special, Royal Wulff, and Royal Trude, remain popular today.

The Zug Bug is a peacock-bodied nymph designed by Cliff Zug of West Lawn, PA in the 1930s to imitate free-living and cased caddis larvae. It imitates many other juve­nile insects also and is an excellent pros­pecting fly for darkly colored mayfly, stonefly, caddisfly, and dam­selfly nymphs. The Zug Bug originated in New York’s Cat­skill Mountains and spread nationally due, in part, to author Arnold Gingrich (The Well Tempered Angler (1965); The Joys of Trout (1973)), who raved about its effectiveness. Even today, Orvis describes the Zug Bug as “easily one of the top 10 nymph fly patterns of all time”. The Zug Bug is quite similar to a vintage pattern of the Pacific North­west named the “Kemp Bug”, and some anglers believe the Zug Bug descended from the Kemp Bug as a vari­ant. History of the Kemp Bug and its ori­gins, however, are poorly documented, and a direct relationship between the two is unconfirmed.

A Zug Bug marries peacock herl to soft brown hen hackle, yielding a combination of color and material that is perhaps the most effective in all of fly design. Brown is the most common color of juvenile aquatic insects, while peacock adds green-olive translucency, sparkle, and quiver­ing move­ments. How many great flies have you known that incor­porate peacock and brown? The list is long, including such notables as the many Coach­man varia­tions, Phea­sant Tail Nymph, Prince Nymph, Rene­gade, Pea­cock Caddis, Brown Beetle, and others.

Fish a Zug Bug deeply with any wet-fly method that you like … dead-drifted down­stream, swung across stream, stripped as a streamer, twitched, lifted through the water column, in tandem with a second nymph, etc. The power of peacock is strong, and you can’t go wrong showing peacock and brown to a trout.
