In the Western United States, the little yellow stonefly is an
incredibly underrated early season bug. Fly fishers tend to focus on
larger stoneflies and early season mayflies before they think of hungry
trout aggressively snatching up puny yellow sallies in the drift.
Recently, however, more and more anglers have discovered the power of
the little yellow stonefly.
Umpqua's Little Yellow Stonefly Female is an excellent imitation of an
emergent or crippled female little yellow stonefly. It's designed with
an attractive yellow body, a prominent yellow hair wing, buggy hackle.
Fish this fly wet and low in the surface film, and you'll be surprised
by the large fish that come to sniff around!
Specifications:
- Little yellow stonefly imitation in the emerger or cripple life stage
- Use as either an impressionistic searching fly or as a realistic imitation when matching the hatch
- Swing the fly through different water types; faster riffles and shallower water near the banks of a river with moderate to slow currents are the most productive water types for this fly
- Little yellow stonefly emergers and cripples are available to trout all year long in trout water throughout North America
- Most prolific hatches occur during warmer months (June – August)
- Hatches occur consistently and with long duration throughout the daylight hours
- Strikes on little yellow stoneflies are often far from subtle because trout must often be prepared to rip these strong crawlers from their rocky homes
- SIZE 16
When and Where to Fish the Little Yellow Stonefly Female
This relatively small emergent or crippled stonefly 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 little yellow stonefly hatch, so be sure to survey the scene
thoroughly. Little yellow stoneflies are available to trout all year
long but are most active during the warmer spring and summer months
(June – August). These stoneflies are active throughout the day in
cool, well-oxygenated water, and are commonly found anywhere trout
thrive. Look for these bugs in the main drift as well as in shallower,
less energetic water near sheltered areas. Prior to and during
emergence, an angler will easily spot little yellow stonefly 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 – this is the sign to
begin fishing the little yellow stonefly hatch.
How to Fish the Little Yellow Stonefly Female
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 little yellow
stoneflies. 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, although some sub-species have been known
to emerge in the water just like mayflies! The typical pre- and
during-emergence behavior renders shallower streamside water quite
productive just prior to and during a little yellow stonefly emergence
and hatch. When fishing with this little yellow stonefly imitation, be
sure to cover both the main drift as well as slower water in eddys and
beneath streamside vegetation. Swing these imitations through these
areas using a standard wet fly presentation. Little yellow stoneflies,
often referred to as “Yellow Sallies,” can make themselves available
throughout the day all year long, but are most prevalent during the
warmer months of June through August. 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!
Little Yellow Stonefly
Little yellow stoneflies (or “Yellow Sallies”) are relatively small
stoneflies that occur with great regularity and in large numbers in
trout waters throughout North America. These pale yellow to light brown
crawling nymphs are widely distributed throughout rivers and streams,
and this broad distribution makes the species and important staple of
any North American trout’s seasonal diet. During the larval stage,
which commonly lasts about 1 year, little yellow stoneflies spend the
balance of their time using their slender, but strong legs, and low
center of gravity to crawl or “creep” about the rocky bottoms of small
to large rivers and spring creeks with moderate to fast flow rates. As
nymphs, little yellow stoneflies display long and slender tails and
antennae and can sometimes display complex patterns along their pale
yellow to brown backs. As winged adults, these insects take on a creamy
yellow or milky straw color and boast the flat wings common to all
adult stoneflies. The little yellow stonefly follows the life stages of
a typical stonefly life cycle and hatches across North America with
great availability throughout the year with more prolific hatches
occurring during the warmer months of June through August.
Little Yellow Stonefly Emerger Life Stage
During its emerger 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 relatively small and slender
emergers can also be found in low energy backwaters, eddys, and other
shallow streamside environments, especially as emergence approaches.
Little yellow stonefly nymphs thrive among the cool, well-oxygenated
water of rocky riffles so look to the slower water adjacent to these
areas for good action. 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 emerging
nymphs expose themselves by making adventurous crawling trips away from
safety just before emergence and subsequent on-land hatching. Little
yellow stoneflies are an important hatch on many rivers in North
America. These easily distinguishable nymphs can become available to
trout throughout the waters of North America on a year-round basis and
commonly hatch from morning to evening hours.
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.”
