The Blue Dun Extended Body is magnificent for imitating natural mayflies. Extended bodies are usually common on larger mayflies like the drakes and hexagenia. When larger hatches are happening, having a few of these Blue Dun Extended Body flies will be key to landing more fish in your net.
They are fished like other dry flies and emergers. The flies are larger making them easier to cast into the perfect places on the water. They work great for still waters and slow moving currents. If you are going for larger fish, this fly pattern is the one to use!
A little flotant will help keep this fly on the surface. The better that you can land this fly on the water, the better chance you will have of a fish striking. Presentation is everything when fly fishing.
