What about a generic mayfly nymph?-The Squirrel Mayfly! When you are fishing on a river that you haven't been to in a long time or you have never visited, it is said that it is good to start with a generic model. That's why GRHE and Pheasant Tail are so popular. Because they are generic models that effectively imitate aquatic insects. Here is this generic model that is very effective and is made with squirrel dubbing. #troutlineshop #troutline #troutflies #flytying #flytyingmaterials #flyfishing
