Best Bighorn River Dry Fly Patterns

All of the patterns featured below catch Bighorn trout each year during the BWO emergence and are must haves for anglers.  All of these patterns have been created to “break the code” when playing the small fly, dry fly game on tailwaters and spring creeks.

Sparkle Dun

CDC Sparkle Dun

1.) CDC Sparkle Dun – This pattern is my go to pattern for every mayfly hatch on the Bighorn.  We carry it in the shop in both grey and olive/brown.  This no hackle fly sits flush in the water and and the sparkle shuck hangs down imitating the nymphal  shuck that the dun is crawling out of.

 

 

 

 

Parachute Biot Dun

2.) Biot Body cdc thorax dun – A very realistic upright dun that is highly effective and easily visible to the angler.  The segmented effect created by the biot body perfectly represents the natural segmentation of the natural insect.

 

 

 

 

Sipper Emerger

3.) Sipper Emerger – This deadly emerger pattern is tied on a curved shank emerger hook that let’s the back end of the fly ride low in the water.  The cdc/deer hair wing makes the fly float well and easy to see.  The biot body is slender and provide segmentation just like the naturals.

4.) Harrop’s Biot Dun – A stealthy bug that rides low in the film. This is a go to pattern that I often trail behind a larger parachute or thorax style fly pattern.

 

 

 

 

 

 

Hi Vis Parachute

5.) Hi Vis Parachute – Because of the smooth glassy surfaces of the Bighorn, glare is often a major variable when fishing dries on the Bighorn.  The multi color post on this parachutes stands out well and is a great first fly for your two fly dry fly rig.

 

 

 

 

Cripple Thor

6.) Cripple Thor – A long time favorite of just about every guide on the Bighorn. This is another great emerging BWO pattern that is most often eaten by large picky fish.

 

 

 

 

 

The Student

7.) The Student- The simplest yet deadliest of flies, this all cdc pattern fools the wariest of trout.  This fly is especially effective towards the end of the emergences seasonal hatch cycle when the trout have seen just about every fly pattern.

 

 

 

 

 

Hi Vis Para Spinner

Hi Vis Para Spinner

8.) BWO Hi Vis Spinner –  Many anglers overlook the BWO spinner fall.  Fish can feed on them throughout the day.  This pattern makes a great point fly as well.

    I would like to tie some of the cripple thor. Could I get a list of tying materials:
    Hook: Dry fly or emerger hook in size 18-20
    Tail: Wood duck or zelon?
    Body: Olive thread or goos biot?
    Underwing: ?
    Wing: CDC

    Thanks for any info.

      Dave,

      The Cripple Thor is a must have during the BWO Hatch on the horn.

      Hook: Standard Dry Fly 18-20
      Tail: Wood Duck or Partridge
      Rib: X Fine wire
      Body: Olive thread – Biots would be really cool, but not necessary
      Wing: CDC – We always use Trouthunter

      Best,

      Steve
