Karen and I were recently fly fishing at a private trout pond with some friends. The 1 acre pond is amazingly enough feed by a spring creek that allows the water to never climb over 15C. There were damsel adults everywhere on the pond and several of the trout were slamming these tasty morsels! Well Karen and I decided to tie on an adult damsel dry that I got from my buddy! It did not take took long to see that damsel disappear into the jaws of a very large rainbow trout!
Adult damsels are usually tied with a piece of 2 mm foam. They are easy to tie and when the trout are on them, it is well worth the effort to try and hook one on the dry!
