CDC Blue Winged Olive 02/18/2022 Photo Album

My post of 02/21/2019 covers much of the basics of this fly. This small baetis imitation continues to be my most productive fly for fooling trout during the spring and fall blue winged olive hatches. The comparadun style allows it to ride low in the water column; and, thus, it imitates adults and emergers. During very windy days; however, it often loses its effectiveness, and for this reason I also stock a supply of Klinkhammer emergers and soft hackle emergers. I theorize that the trout pick off emergers below the surface because the adults get swept away by the wind in rapid fashion.

Trout Food

Last year, however, I formed a new theory on this windy day conundrum. During wind gusts the adults skitter across the surface, and my observation suggests that perhaps the trout look for small insects with a lot of movement. For this reason I may tie up a few fully hackled blue winged olives to create the illusion of tumbling wind-blown food morsels.

15 New Ones

When I counted my supply of size 22 CDC BWO’s, I discovered that I was a bit low, so I churned out fifteen additional copies. These should keep me in adequate supply over the coming season. In addition I produced five new size 24 CDC BWO’s in case some of my lack of success during hatches results from the presence of very small mayflies.
