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

by Rusty Dunn

A mid-summer day in the late 1940s begins like many others in Pennsylvania’s fertile Cumberland Valley.  A young Vince Marinaro fishes the crystalline wa­ters of Letort Spring Run.  The day is brilliantly sunny, and as the heat builds, so does Marinaro’s frustration.  Insects are seemingly nonexistent, yet many fine trout rise stead­ily in the creek’s weedy channels.  The riseforms are slow and deliberate, leav­ing only the faintest hint of a ring.

Marinaro has spent several days trying to decipher what the rising trout feed upon.  He casts a box full of dries, wets, and nymphs with little success.  He fishes atop the sur­face, in the sur­face, under the surface, and near the bottom.  Noth­ing.  He gives his flies a little twitch or a slow retrieve.  Still nothing.  He casts to a dozen steady risers, and one-by-one they stop feeding.  Marinaro’s frustration finally boils over.  He quits fish­ing, sets his rod aside, lays flat on the ground, and crawls like a spi­der to the water’s edge.  Perched within inches of the surface, he intently scans for signs of life.  Noth­ing.  After a few minutes of hyp­notic study, though, he begins to see things.  Tiny things.  Insects he had initially overlooked.  Tiny may­fly duns struggling to shed their nymphal skins, bee­tles smaller than he thought pos­si­ble, and tiny little leaf­hop­pers.  Marinaro is stunned by the minia­ture world be­fore his eyes, revealed suddenly as if a curtain had been raised and the stage lights switched on.  He hur­ries to a nearby fishing hut, finds a mesh bag, fashions a work­able seine, and returns to the stream to seine the current.  The net is alive with tiny insects.  Bee­tles no more than 3/32″ long; winged and wing­less red ants so small that their slender waists are nearly in­visible; unimaginably small mayfly nymphs and emerging duns; tiny green leafhoppers about 1/8″ long; little inchworms fallen from the trees; and black ants, unseen at the surface be­cause they drift under­water.  Marinaro’s day ended in won­derment, for he had discovered the world of tiny ter­restrials.

The classic angling literature frequently discussed ter­restrial insects that fall or are blown into trout streams, but their importance as late sea­son trout fare was rarely emphasized.  As the hatches of spring de­cline, aquatic insects become increasingly scarce, and terrestri­als can sustain trout for months.  Mari­naro described his day of discovery on the Letort in his 1950 book A Modern Dry Fly Code, in which he devoted about a third of the contents to terres­trials and their imi­tation.  Marinaro’s Jassid pattern is an excel­lent imitation of small beetles, but it was never very popu­lar.  Jassids re­quire jungle cock nails, an exotic bird spe­cies whose feathers have always been rare and expensive.  The scarcity of jungle cock made the Jassid itself an endangered species.

Meanwhile, Pennsylvanian John Crowe was a con­temporary of Mari­naro’s from the nearby steel town of Johnstown, PA.  Crowe fished many of the same streams as Marinaro and designed an affordable bee­tle imitation that is still popular today.  It is a model of simplicity and was first described in Crowe’s 1947 book The Book of Trout Lore.  Marinaro’s Jassid was a blue-blooded fly in­tended for fly fish­ing’s cogno­scenti.  John Crowe’s beetle was a blue-collared fly in­tended for fly fish­ing’s rank and file.  Both are first rate flies, but Crowe Beetles won’t break the bank.

Fish a Crowe Beetle anytime from early summer to season’s end, especially along grassy banks and near over­hanging trees.  The fly can be dif­ficult to see, but a spot of paint or a tuft of bright yarn tied over the back aids visibility.  Crowe Beetles are frag­ile, but don’t be concerned when they become tattered; they fish even better that way.  Many accomplished an­glers maintain that Crowe Bee­tles are more effective than the ubiquitous and wildly popular foam beetles.  Foam bee­tles float well, are easy to see, and are dura­ble, but they are soul­less gobs of synthetics.  When the weather warms and the ter­restrials of summer come calling, fish with passion.  Fish with history.  Fish with John Crowe’s steel town beetle.
