If you've ever fished slow, lazy water, you know that big, hungry
trout love to lurk in the weeds. These big fish love to hold their
positions in the soft current, waiting for that perfect moment to rise
and take a sip on a helpless crippled Callibaetis.
The Mayfly Cripple Callibaetis an excellent imitation of the Callibaetis
mayfly in the crippled life stage. It's also the perfect fly pattern to
have strung on your leader when the water is cool and slow and you've
spotted the first few of these greyish-blue mayflies fluttering off the
water's surface. With a whack of stiff, hollow fibers and a puff of CDC
feathers for a tail, this fly rides right in the surface film and shows
a realistic profile that will tantalize even the most wary trout!
Specifications:
- This fly pattern boasts thick forward hair wings for floatation, a stiff hackle collar, a long and slender abdomen, and a puff of CDC feathers to imitate a trailing shuck
- Its excellent buggy profile makes it an attractive morsel to hungry trout
- Callibaetis imitation in the cripple life stage
- Use as either an impressionistic searching fly or as a realistic imitation when matching the hatch
- Twitch the fly through slow water; lakes, backwater, and eddys are the most productive water types for this fly
- Best results during summer months are obtained mid-morning
- When the weather and water temperatures are a bit cooler, look for Callibaetis in the late afternoon
- Strikes on Callibaetis cripples are often far from subtle because trout must pursue them aggressively
- SIZE 16
When and Where to Fish the Mayfly Cripple Callibaetis
This relatively small mayfly cripple 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 the
still waters of lakes or the slow backwaters and eddys of rivers. Callibaetis
are active at mid-morning during the summer months and later in the
afternoon once the weather and water temperatures cool off during the
fall and winter seasons. Even though Callibaetis
are technically crawling nymphs, they happen to possess strong swimming
ability, making the emergent and crippled stages important for fly
anglers to imitate. Prior to and during emergence, an angler will find
these nymphs darting from weedy cover to hatch. When fishing the Callibaetis hatch, look for darkening wing pads, a sure sign of an impending hatch.
How to Fish the Mayfly Cripple Callibaetis
Fish this fly in very slow water; lakes, backwaters, and eddys are
prime real estate for these large burrowing nymphs. Generally, the
slower the water and the weedier the bottom, the more packed with Callibaetis nymphs the environment will be, rendering lakes excellent Callibaetis
water. Note that these emerging bugs will dart about prior to and
during their hatch, so when fishing this fly pattern in a lake or river
environment, don’t be afraid to “swim” the fly during the presentation.
Gently jerk the rod tip up and down or feed line back and forward
through the guides with your stripping hand to imitate the struggle of
a crippled mayfly. When Callibaetis
make themselves available during mornings or evenings, trout prey on
them hungrily and voraciously – especially when hung in the shuck.
Don’t be surprised when you feel an aggressive take – set the hook
confidently!
Callibaetis
Callibaetis are relatively
small mayflies that occur in the famous trout waters of the North
American West. In this storied fly fishing region, these insects are
widely distributed throughout rivers and lakes, and this broad
distribution makes the species and important staple of a western
trout’s diet. During the larval stage, Callibaetis spend the balance of their time in the weedy shelter of slow moving water provided by rivers, spring creeks, and lakes. Callibaetis
follows the life stages of a typical mayfly life cycle and hatches
across the western United States from spring (April) to mid-fall
(October).
Callibaetis Cripple Life Stage
During its nymph life stage, these crawlers are most commonly found in
the slow water environments of lakes. In river systems, these
small-to-medium sized nymphs call low energy backwaters, eddys, and the
gentle currents of vegetation-rich spring creeks home. Callibaetis
nymphs thrive among the weedy vegetation of these slow and languid
aquatic environments, and these nymphs are most vulnerable to trout
when they leave their weedy shelter to hatch into winged adult duns,
making the emerger and cripple life stage an important one for both fly
anglers and feeding fish. Their swimming ability is relatively strong
and these emergers expose themselves by making adventurous trips away
from safety just before emergence and subsequent hatching. When hung in
the shuck or crippled, these bugs are extremely vulnerable to feeding
trout. Callibaetis is an
important hatch on many rivers and lakes and are available to trout
throughout the Western United States from spring (April), through late
summer, and into the fall season (October). When temperatures are warm,
these emergers are most active during mid-morning hours. During the
milder months, an angler will find Calibaetis activity later in the afternoon. These olive green or light tan nymphs are easily distinguishable from other members of the Baetidae family by their possession of three dark-colored tails of nearly identical length.
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.”
