The pheasant tail nymph is one of the oldest flies still in general use. It has remained popular over the years because it is incredibly effective. It mimics a variety of freshwater organisms that fish like trout love to eat. When nothing else works a small pheasant tail will often prevail. The hot spot pheasant tail adds a center of attraction to the head of the fly which can draw fish in when nothing else will work. This is a go-to fly.
