CDC Blue Wing Olive 02/14/2025 Photo Album

For a look at my history with this fly inspect my post of 02/18/2022. I was unable to search for more recent posts, so this leads me to believe that I have not tied these flies in a few years. That is hard to accept, because I use and lose these tiny morsels quite frequently; however, I used my chronological listing of posts to scroll back through fly reports for 2023 and 2024, and I found no more current titles referencing CDC blue wing olives. It is also possible that I forgot to complete a write up.

Size 20

At any rate, I tie these flies in three sizes; 20, 22, and 24. I also tie other small blue wing olive imitations such as the Klinkhammer version and soft hackle emergers. Generally the CDC BWO tied comparadun style gets the job done, but frustrating episodes, where the fish ignore my trusty mainstay led to experimentation with variants. Recently small soft hackle emergers fished in the film with floatant have brought a degree of success particularly during windy conditions. I suspect the soft hackle and the swept back fluoro fiber wing represent a cripple or a fly struggling to get airborne in cold temperatures with strong wind.

Minute Size 24

I also suspect that the trout key on movement, and the dead drifting motionless CDC blue wing olive does not cut it, when motion is the image that trout are scanning the surface for. For this reason I tied a few hackled CDC BWO imitations to experiment with in the upcoming season. I made these in size 22, and they are the same as a CDC BWO, except that they feature a small hackle collar wound behind and in front of the wing.

Hackled Variety

My annual count of CDC BWO’s suggested that I tie four size 20’s, two size 24’s and five size 22’s with hackle. I am anxious to continue the experiment with CDC BWO variations in 2025.
