This is a very good UK site that depicts a multitude of flies for fresh and saltwater conditions. Fish4flies is in business to sell you flies. For some that is the accepted practice because they do not have the inclination to buy materials and tie. For others this site affords an opportunity to see excellent representations of patterns. For those of us in the U.S. some of the flies are not typical of what we see and there are fun new discoveries to be had. No design concepts, names, fresh ideas. I am certain UK tiers find new ideas cruising other sites as well. It all blends together around the world. http://www.fish4flies.com/Nymphs/
