Trout Flies

One of my childhood memories was of trout fishing in Colorado.  My parents owned a cabin in northern Colorado and we would spend time there and fished.  Occasionally, I sketch trout flies like these above.  I don't remember these flies's names but I know the bottom two are a Salmon egg fly and a midge fly.  I actually sketched these from memory while waiting in the theater to see the movie, Avatar.  I liked the sketches better than the movie.
