This pattern imitates the nymph stage of our two largest mayflies, Ephemera vulgata, that is most common in lakes, and Ephemera danica, that is most common in slow flowing rivers and streams. These nymphs prefer sandy or muddy bottoms, where they live more or less buried for two to three years. These large nymphs can be recognized by the breathing gills along the sides of the rear body. Nymph patterns like this one should be weighted, so that they don´t swim up side down in the water, this should be done by tying in two strips of lead wire on the underside of the hook shank. The R73 hook from Mustad that I have used here is so heavy in the bend that it will swim the right way even if you use extra weight under the thorax. On these large nymphs I prefer to use Golden pheasant as the wing case. These tail feather fibers are tougher than normal ring neck pheasant tails fibers and have a little more shine.

One thought on “Mayfly Nymph-omaniac”
Great minds think alike! Take a look at my two recent blog posts, in which I write about the “gill bodied nymph”. I have done mine with V rib instead of the dubbing, to give an exo-skeletal body, as well as to protect the fine ostrich herl between wraps. But also trimmed top and bottom.
