Damsel nymph.
Yeah ok, I can see where this series is going - but this is actually my best nymphet. Honest. I catch a lot of fish on this, much more than you think. In fact if you were to say to me, "Paul, take one fly out of you box and catch me a fish" then this would be it. Difficult to believe, I know. But life's like that sometimes.
It's sort of based on a John Goddard mayfly pattern, and yeah, it's a great fly. So you'll want one of these. Definitely.
Tying instructions:
lots of green stuff.
