Fall Fishing: Blue Winged Olive CDC Cripple

fallFall and winter are times to experience some fun Blue Winged Olive hatches. The flies are going to be small but it can be exciting. When fishing during a BWO hatch you may have your best luck in moderate to slow runs and back eddies. These small flies often struggle breaking through the surface, so emerger patterns are often very successful fly patterns to use. Two of my favorite patterns to use are a Foam Biot Emerger and a CDC Cripple.

I have been tying these and other flies commercially for the last couple years for customers and fly shops. You can find out a little more about me and see these flies and other patterns that I have listed here at .

BWO CDC Cripple info
I like this pattern because of the use of CDC. I have found that you can be really creative with CDC and it fishes really well too. It creates a lot of movement and can be life giving to your fly.
Hook: Dohiku G644
Thread: Olive 8/0
Tail: dun antron
Body: Olive biot or Olive died peacock herl
Wing: Dun CDC
Thorax/head: small amount of dubbing

Step 1: Tie in the tail material. I like to have the tail material the length of the hook so that I can have an even body to wrap the biot or the peacock herl onto. After it is secured, move the thread to the back of the hook and cut the length of the tail to desired length.

More after the break here.

Step 2: tie in the biot by the tip. Move the thread forward to about two eye lengths behind the eye of the hook.


Step 3: wrap the biot forward and tie off.

Step 4: Take two or three cdc feathers to create the desired thickness of cdc. I like to have the tips extend to the hook bend or shorter. Then cut the feathers off.

Step 5: For the final step, take a small amount of dubbing and build a small head. Then whip finish.

Here is the same fly with the olive died peacock herl:

I found that the same pattern with a bit more antron trailing off the tail to simulate the nymph shuck to be deadly. especially on overcast days. Nice article.
