My previous post on the zebra midge largely covers the effectiveness of this diminutive subsurface fly, and I have little to add here in late December 2014.

I counted 18 in my fly bin, so I decided to tie an additional two to bring my total to 20 as I approach the 2015 fishing season. In addition my supply of dark olive zebra midges dwindled to only a few in my fleece pocket, so I produced an additional three of that variety.

How can fish see these tiny morsels as they drift in the large rivers of Colorado? It remains a mystery to me, but I do know that they produce, and I will continue to tie them to my line in likely midge feeding situations.
