If you fish tailwaters, midges are ubiquitous. I’ve seen clouds of them hatching in the mornings at the Farmington, and a midge pupa is an extremely effective dropper fly for nymphing there. Midge larvae and pupae are in the drift all day.
At times, I want to throw small dries. So, I am reloading.
The trick is to be very abstemious with your thread turns and to look at times at the bottom of the fly to make sure the body looks tapered but not too thick. I’ve used thin Veevus 16/0 thread in the past, but UTC 70 denier thread can work, too. You just need to flatten the thread by spinning it counter-clockwise. A CDC loop completes the pattern and provides flotation and visibility.
Black is the norm, but I am playing around with different colors to give the trout a different look. For example, here is a size 30 CDC Midge Emerger in purple.
- Hook: Gamakatsu C12-BM, size 30 (barbless, has a large eye)
- Thread: UTC, 70 denier, in black, dark grey or purple
- Wing: CDC in white, grey or dark dun
