The Black Quill Nymph - Nymph - is a majorly underestimated imitation, when used in the correct conditions all manner of trout cannot resist this pattern. The black quill nymph tends to reside in slower water; however, it is no stranger to faster stretches. If an angler is lucky enough to come across a hatch of Black Quill Nymph then a good day is a guarantee, as trout love nothing more than to satiate themselves on the schools of these flies.
