The Light Cahill is a classic Catskill pattern originally developed for use in the Eastern US, but has become very popular throughout the entire US. This fly can be used to imitate a great variety of light colored mayflies.

This classic Catskill pattern proves itself year after year! It was originally tied in 1916 by Roy Steenrod and remains very popular today. Although native to the Catskills, this pattern is very effective in most trout waters.
