It’s a sad truth: many of the world’s midge fly patterns look the same,
leaving many of the world’s fly anglers to ignore the importance of
these small, wormy creatures. Trout love midges and depend on them for
survival, so the mighty midge should most certainly not be considered
too boring to be useful.
Leave it to professional fly tyer and
fly fishing junkie, Mike Mercer, to inject his signature creativity
into the world of midges.
Mercer’s Midgeling really does stand
out among the crowd of standard midge imitations available to a fly
angler today. Mercer’s take on the simple, wormlike midge larva is
packed with an attractive iridescence through its slightly tapered body
and a buggy set of contrasting forelegs. The fly is neatly topped by a
glass bead with soft lines and a realistic translucence that will
surely fool the wiliest trout in the hole.
Specifications:
- Creative fly tyer, Mike Mercer’s best midge imitation to date
- Creative and elegant use of materials to spice up a simple midge imitation
- Midge imitation in the mature larval life stage
- Fishes effectively in all types of trout water
- Dead drift through slower water and eddies
- Faster riffles and current seams can also be great spots to dead drift a midge larva pattern
- Midges are often most effectively fished when attached as a dropper to a larger nymph or when fished just below the water’s surface with a large dry fly as a strike indicator
- Because of the common and widespread nature of midge species, trout anglers ought to keep a wide selection of midge fly patterns in their fly boxes

When and Where to Fish Mercer’s Midgeling
This elegantly
simple midge nymph is most effectively fished as an impressionistic fly
pattern when searching for trout. When searching, fish this fly in all
types of trout environments. Roll it along the bottom of the still
waters of lakes or the slow backwaters and eddys of rivers and spring
creeks or dead drift it through faster riffles and current seams.
Because midge populations are so widespread and so prolific in numbers,
a fly angler can always count on finding a solid selection of midges in
the water they fish. Simply turn over rocks or drag a net through the
main current to find the color and size of the midges in your local
water. Midges are active on water across North America throughout the
year and are an important source of nutrition for feeding trout.
How to Fish Mercer’s Midgeling
Fish
this fly in all types of trout water. Slow water, backwaters, eddys,
and spring creeks are prime real estate for these small midges, so
drift them through these areas to see what action they turn up. These
wormy larvae can also be quite easily caught in the main current, so
don’t be afraid to dead drift a midge pattern right through a
well-defined current seam. Although anglers will find great success on
lots of rivers and lakes with these simple techniques and a single
midge pattern, the most effective use of a midge larva pattern is in
concert with a larger nymph or dry fly. Tie on a midge larva as a
dropper behind your favorite mayfly nymph during a heavy hatch or fish
a midge larva with a large dry fly as an indicator – these strategies
can yield big results!
Midge
Sometimes referred to as “True Flies,” midges are
aquatic insects of the order Diptera, meaning two-winged. Most people
are familiar with the common mosquito which is a midge, and most trout
are familiar not only with the mosquito, but also with the hundreds of
other species of midges that can be found in their watery homes. Midges
are relatively small aquatic insects that can be found in just about
any freshwater (and brackish) environment on the planet, and despite
their diminutive size, the hundreds of species of these mosquito-like
bugs compose a quite significant portion of a healthy trout’s diet.
Midges, like caddis, undergo a complete metamorphosis, and experience a
larva, pupa, and adult life stage within a typical life cycle.
Midge Larva Life Stage
During
its larva life stage, these small wormy insects are commonly found
throughout the many different types of water where trout are found.
Midge larvae are often transparent and take on hues of color; green,
red, cream, tan, and black are the most common colors for these small
larvae. Midge larvae can be found in large numbers among rocky and
debris littered river bottoms, along the shorelines of lakes, and
floating along the main current of rivers and spring creeks throughout
North America. These relatively defenseless insects are vulnerable to
feeding trout at any point during their life cycle and these simple
larvae can produce excellent results for trout anglers fishing anywhere
in the world.
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.”
