Springtime is the awakening for many aquatic insect species. Nymphs of several common insects that fish like to eat share similar characteristics. Often their emergence overlaps with other species, and then an aquatic smorgasbord is offered to fish. So a single, generic form of nymph will often cover a lot of circumstances when those critters are active. Size, shape, movement, and colour are key factors of interpretive and effective nymphal fly design. The Zug-bug is one of those “close enough” buggy-looking imitations that take fish consistently.
