Mayfly Cripple & Emerger Index
                              $24 per 1/2 doz. 

CDC Model A Emerger
Devised in response to the extreme selectivity of trout isolating on PMD Mayflies in transition from the nymph to the dun stage. Fished either in the film or submerged, this pattern can also be effective for any mayfly that emerges in the water. 
CDC PhD Emerger
Showing great promise, a new pattern for those times when trout become ultra-selective. Fished dead drift in the film.
CDC Biot Captive Dun
Perhaps the single most sensible emerging pattern we have ever designed.  Remarkably visible yet deadly for fish that are hunting the most vulnerable mayflies.
CDC Floating Nymph
A much older concept gains even more reliability with this basic configuration of a nymph utilizing the color of the dun. 
Short Winged Emerger
Bonnie's Short Winged Emerger continues to prove itself time and time again.  With versatility being this patterns most valuable feature, fish it dressed in or beneath the film.
Half and Half Emerger
Derived from Bonnie's time honored 'Short Wing Emerger,' this low-floating pattern targets a mayfly in a partially emerged state. Particularly useful during a PMD hatch. 
CDC Transitional Dun
Transitional Duns have proven to be among the most productive and popular of our Cul-de-Canard patterns. They are a representative of a winged emerging dun that is still connected to the nymphal shuck. This pattern has a higher profile and is quite easy to see on the water. It floats beautifully  and has proven itself around the world.
CDC Biot Cripple
Unable to completely free themselves from the nymphal shuck and escape from the water, their helpless condition presents an easy target for hungry trout.  This pattern is tied to float with great visibility.
CDC Paracripple
This parachute style cripple displays both colors of the nymphal shuck and dun.  Great flotation and visibility. 
CDC Last Chance Cripple
Among our top sellers and popular with float fisherman, this hanging pattern's excellent flotation and visibility makes it  a superb indicator fly for hanging a nymph beneath the surface.
Hairwing Biot Cripple
Tied Comparadun style, this Hairwing Cripple floats beautifully. The biot 
abdomen simulates the shedding nymphal shuck while the thorax color 
represents the emerging dun.
Biot Sparkle Dun
Another Comparadun style, this pattern features the color of the dun with a 
trailing shuck to simulate vulnerability.
CDC Biot Emerger
A simple, versatile, and productive style, this emerging pattern doubles as a dun imitation. The addition of the CDC wing and soft hackle collar to our Biot Emergers has produced a strikingly lively and effective emerging pattern. They are wonderful for low, clear water where flies receive close scrutiny from large trout. The colors of these delicate emergers are slightly exaggerated to duplicate the color intensity of a freshly hatched mayfly. They are at their best when fished in the film using conventional dry presentation and are quite easy to track on the surface. 
CDC Tailwater Dun
Patterns depicting fully developed mayfly duns should not only float well, they also need to closely resemble the actual insects they are intended to duplicate. Our Tailwater Duns feature a highly visible wing of Cul-de-Canard mounted at precisely the correct angle. Balance and floatation are further enhanced with additional Cul-de-Canard positioned at the sides of the fly as legs. Viewed from beneath, this "No-Hackle" style reveals a clearer view of the body of the fly. ​Tailwater Duns are extremely accurate representations of the important hatches across the country. They float well, are easy to see and are very durable.
