This fly is called a "wet fly" because it is to represent an insect struggling in the water. It is suggestive becuase it does not represent any particular insect. When cast, it is to float just under the surface, and fish believe it is an easy take! It is tied with rooster hackle, peacock herl, and pheasant tail feathers. Feathers make up this entire fly! There are many green abdomen Mayflies, and this fly is probably mistaken for one. Wet flies are very enjoyable to use by casting gently to the water and allow it to float barely under the surface for a few seconds. Then decide if to show it as an insect that escapes or one that drowns. When a fish catches a wetfly, it is most exciting when acting as though the fly escapes. The fish must swim very quickly and often times jumps out of the water! Have fun and experiment. That is the best part of fishing!
