Fly Description
The Sparkle Pupa is one of the most revolutionary caddisfly imitations in fly fishing history. Developed in the 1970s by legendary angling author and researcher Gary LaFontaine, this pattern changed how fly tyers approach insect imitation. Rather than focusing purely on matching the silhouette of a dead bug, the Sparkle Pupa was engineered to capture a dynamic, natural underwater optical effect: the glistening gas bubble trapped by a pupating caddis.
