Taking inspiration from one of the most popular flies around, the WD-40, the WD-50 picks up right in its path of success. Designed by Carl Stouts, the WD-50 is an effective nymph that will imitate anything from tiny mayfly nymphs like BWOs to midge pupae. Modeling itself after the original pattern but adding a couple of twists, the WD-50 has a slim thread body, mallard fiber tail, flashback wingcase (perfect for imitating those freshly emerging nymphs), and a mallard wing bud. A relatively simple design but one that works well in a variety of environments, the WD-50 is a fly that can be fished all year long.

Whether you’re matching emerging insects or just bumping the bottom of the stream, the WD-50 proves effective, with sizes 18-20 being the most popular sizes. A great fly for fooling picky fish or whenever you need that perfect dropper nymph, the WD-50 will help you get into fish, whether you’re casting to fish gorging on BWO nymphs or ticking the bottom hoping to connect with a monster.
