The sprout is a killer mayfly emerger that comes in a number of forms, including BWO, callibaetis, and trico, and one of our Top PMD Flies.

The bulk of the fly rides below the surface, including an antron shuck and lightly dressed body. The hackle of the fly rides even with the surface film tied around a foam post. The white foam post gives this emerger an advantage over others, giving the angler better visibility and tracking without sacrificing the appearance or presentation of an emerging PMD. Additionally, the foam post allows you to fish the sprout in riffles or more turbulent water without drowning the fly.
