Mike Mercer is a truly exceptional modern fly tyer, notably for his
clever uses of natural and synthetic materials. His ingenious series of
"Poxyback" mayfly nymph patterns exemplifies this ability to mash up
materials to create a wildly effective fly.
Mercer's Bead Head Epoxy Biot Golden Stonefly is the logical extension
of the Poxyback style from the mayfly to the stonefly, and serves as an
excellent imitation of the golden stonefly in its mature nymph or
emerger life stage. With its thin profile, biot-wrapped body, wiggly
feather gills, flashy bead head, and "wet" epoxy shell, this smartly
dressed fly is sure to pick a fight with the biggest steelhead and
trout in your favorite pool!

When and Where to Fish Mercer's Bead Head Epoxy Biot Golden Stonefly
This medium sized stonefly nymph can be fished as either an
impressionistic fly pattern when searching for trout or as a realistic
imitation when matching the hatch. When searching, fish this fly in
riffles, well defined current seams, areas below faster currents, and
near exposed rocky structure and streamside vegetation. Shallow water
near the river bank will also be productive when fishing a golden
stonefly hatch, so be sure to survey the scene thoroughly. These nymphs
do not possess strong swimming ability, however, and are often swept
into the main current’s drift – look for these floating specimens in
the main drift as well as shallower, less energetic water near
sheltered areas. Prior to and during emergence, an angler will easily
spot these nymphs crawling from the rocky depths to the shallower water
along the river bank and eventually to the surface of exposed rocks and
vegetation to shed their shucks and hatch into winged adults.
How to Fish Mercer's Bead Head Epoxy Biot Golden Stonefly
Fish this fly in a variety of water types; because of their aggressive
and migratory feeding nature, strong crawling ability, and widespread
proliferation in all kinds of trout water, just about anywhere within a
healthy aquatic ecosystem can be prime real estate for golden stonefly
nymphs. Despite their strength as clinging nymphs, golden stoneflies
will often be carried away by stronger currents. These poor swimmers
are unable to fight the power of the main drift and will ride the wave
until the energy decreases and they are deposited back onto the safety
of the river bottom. When these nymphs are caught in the drift, they
are quite vulnerable to feeding trout and will quickly meet their
match. A popular strategy is to fish these patterns on a dead drift
right through the main current – drifting a golden stonefly nymph
through faster riffles, current seams, and the slower water just below
these areas can yield excellent results. Stonefly nymphs emerge after
crawling to the safety of the shoreline rather than shedding their
nymphal shucks in the water’s surface film like mayflies. This pre- and
during-emergence behavior renders shallower streamside water quite
productive just prior to and during a golden stonefly emergence and
hatch. Always be sure to cast far enough upstream to allow your golden
stonefly nymph time to sink; this species spends most of its 2 or 3
years as a nymph in the lower portions of the water column. Golden
stones make themselves available throughout the day all year long.
Trout prey on them hungrily and voraciously, so don’t be surprised when
you feel an aggressive take – set the hook confidently and with care if
you happen to be fishing with lighter leaders and tippet material!
Golden Stonefly
Golden stoneflies are medium to large stoneflies that occur with great
regularity and in large numbers in trout waters throughout North
America. These golden brown clinger nymphs are widely distributed
throughout rivers and streams, and this broad distribution makes the
species and important staple of any North American trout’s regular
diet. During the larval stage, which commonly lasts anywhere from 1 to
3 years, golden stoneflies spend the balance of their time using their
powerful legs and low center of gravity to cling to the rocky bottoms
of small to large rivers and spring creeks with moderate to fast flow
rates. As nymphs, golden stoneflies display pronounced tails and
antennae as well as richly colored golden bellies. As winged adults,
these insects take on a rich straw, toffee, burnt cream, or golden
umber color and boast the flat wings common to all adult stoneflies.
The golden stonefly follows the life stages of a typical stonefly life
cycle and hatches across North America with great availability
throughout the year, making the species one of great importance to both
trout and fly anglers who try to fool them.
Golden Stonefly Emerger Life Stage
During its nymph life stage, these crawlers are most commonly found in
the medium to fast water of riffles and higher energy current seams.
Prior to and during a hatch, these medium-to-large sized nymphs can
also be found in low energy backwaters, eddys, and other shallow
streamside environments. Golden stonefly nymphs thrive among the cool,
well-oxygenated water of rocky riffles and these nymphs are most
vulnerable to trout when they are either swept up by strong currents or
when they leave their rocky homes to hatch into winged adults from the
safety of the shoreline. Their swimming ability is quite weak and these
nymphs expose themselves by making adventurous crawling trips away from
safety just before emergence and subsequent on-land hatching. Golden
stones are an important hatch on many rivers in North America, and in
the west, they are often associated with the prolific hatches of the
giant salmonfly, which generally precede the hatches of the golden
stonefly. These easily distinguishable nymphs are available to trout
throughout the waters of North America on a year-round basis and
commonly hatch from morning to evening hours.
About the Tyer: Mike Mercer
Mike Mercer is a self-proclaimed “hopeless fly fishing junkie with an
incurable addiction to the vise.” Such honest and direct words are not
surprising from Mr. Mercer, a fly angler and tyer known for his
innovative uses of fly tying materials and creative fly designs. In
fact, it wouldn’t be off the mark to say his fly patterns actually
reflect both his honesty and directness.
Mercer has been fishing all his life, but catching his first smallmouth
bass on a fly rod blew open the proverbial gates, sending him deep into
the fly fishing world. With the help of his grandfather’s old pickup
truck, Mercer explored the fantastic trout water of California’s rich
wilderness areas. With his youthful enthusiasm for traveling with a fly
rod, he actually opened a fly shop of his own. At Mike Mercer’s Rod and
Fly (doubling as the basement of his parents’ house) a fly fisher could
find a selection of custom fly rods, fly fishing and fly tying
magazines, and Mike himself, behind the vise, whipping up box loads of
custom flies.
As a fly fishing guide, writer, travel consultant, and creative fly
tyer, Mercer has been able to form a unique perspective on the sport
and share it with other fly anglers across the world. His fly designs
have appeared in magazine, in books, and with the help of Umpqua
Feather Merchants, anglers across the globe have been able to fish a
Mike Mercer creation hard and with great success in waters near and
far.
Mercer’s designs often hinge on an idea that “seems obvious” but from a
design perspective, these are often the very best kinds of ideas.
Mercer continues to create great flies and is a tremendous resource to
the fly fishing and fly tying community.
Leland on Umpqua
In
1972 a man named Dennis Black and his fly tying skills found themselves
in high demand. Mr. Black, then a professional production fly tyer, was
famous in the industry for his unsurpassed skill and speed with
whipping up tremendously beautiful and precisely constructed flies. It
wasn’t long until this young fly tying superstar realized that he ought
to take his consistent approach to quality to the next level. Shortly
after this realization, a small army of fly tyers had banded together
to support Mr. Black’s vision. With the likes of Dave Whitlock, Jack
Dennis, and Andy Puyans, Mr. Black was officially in business.
Dennis
Black’s new company Umpqua Feather Merchants quickly extended its reach
and fly production capabilities with expansion into India, Sri Lanka,
and Thailand, where the world’s first and full blown “fly tying
factories” were built. Since those early days, only the highest
standard of excellence has marked Umpqua and this commitment to quality
and efficiency continues to spur the company forward. Dennis Black’s
innovative vision for “fly production” has truly revolutionized how the
fly industry operates and has ultimately made the majority of
production flies better. From the first “royalty system” for rewarding
the most creative professional fly tyers to streamlining production
systems and offering a range of other products, Umpqua Feather
Merchants just seems to “do it all.”
Today, Umpqua Feather
Merchants is without a doubt the world’s best and most prolific
supplier of hand tied fly fishing flies as well as fly tying hooks and
materials, and they recently got better! Umpqua’s brand new, state of
the art headquarters in Louisville, Colorado marks another paradigm
shift in the way fly tying business is done. From its vast warehouse to
its specially designed inventory management and tracking system, Umpqua
is poised to continue its energetic trajectory and lead the way for the
next generation of flies and fly tyers.
Umpqua on Umpqua
"As you may or may not know, we're the
largest producer of quality hand-tied flies in the world. We also make
available through your local fly shop a wide array of the finest
fly-tying hackle and Tiemco hooks.
At Umpqua we offer
everything the angler needs to a have a first class fishing experience.
(Everything that is, but the water and the fish.)"
Umpqua on Dennis Black and the “Obvious Quest”
“The idea
first took shape in the hands of our founder, Dennis Black, back in
1972. As a fast and facile professional fly tyer, Dennis was known for
his skill and speed at producing hundreds of dozens of flies each year
for the larger mail order houses. But he was also quick to realize how
fast the demand for excellent flies would outstrip the abilities of
cottage industry types like him.
The Obvious Quest: To create
excellent flies in sufficient supply – without sinking his standards.
In response, Dennis developed (with characteristic care) a methodical
plan: First, he enlisted the tying expertise of the likes of Dave
Whitlock, Jack Dennis, Andy Puyans and others, to help him set the
standard of excellence for Umpqua flies.
Next, Dennis
established the first of what would eventually be five separate
fly-tying “factories,” first in India, then in Sri Lanka, and finally
in Thailand. The primary focus at each of these factories was on
producing the very best fishing flies possible, constructed of the very
best materials available. From the beginning, the quantity of flies
produced was secondary to the quality and excellence of each fly
pattern. These high standards were assured by the personal involvement
of the fly designers themselves, and by the ever-increasing skill,
imagination and creativity of the Umpqua production fly tiers. Today,
you will find no flies more skillfully tied than those available from
Umpqua Feather Merchants.
Finally, Dennis created a system of
royalty payments, to reward professional tyers like Whitlock, Lefty
Kreh, Randall Kaufman, Larry Dahlberg, and Bob Popovics for uniquely
good patterns.
The Result: Today, Umpqua produces umpteen
thousand dozen flies, from micro-scopic midge imitations to the huge
patterns favored by marlin and sailfish. And the "Umpquality" – you’ll
see for yourself.”
