Yesterday afternoon I walked down to Lone Lake (whidbey Island) to look at the number, and type, of bugs on the water. The first thing I noticed were the sheer number of adult chironomids on the water. As I am looking and watching the varieties of chironomids, a water boatman swims past me, just out of arms reach. I don't encounter these bugs often but have seen them before. This however was my first time watching one swim just under the surface, in an erratic swimming motion, sort of damsel-esque, jutting left to right, but much faster than a damsel. I rarely fish boatman or backswimmer patterns and have only landed one fish using this fly. This was in the Fall, and it was not until one flew into my neck that I tied on the imitation. I am wondering, do others fish this pattern during spring? If so, what is the approach and how do you imitate the erratic swimming motion I saw yesterday? Thanks!
