Parachute Light Cahill

The Parachute Light Cahill is an updated take on the classic Light Cahill dry fly, a pattern that has been used for generations to imitate pale-bodied mayflies. Traditional Cahills were known for their clean, high-floating profile, but tiers later adapted the parachute style to improve stability and keep the fly riding flush to the surface. This version maintains the delicate, lightly colored body of the original while offering better visibility and a more natural footprint during slower drifts.

Trim a tiny V-notch out of the hackle directly beneath the hook eye. This creates a subtle forward “hinge” that helps the fly pivot and settle flat in micro-currents—an advantage when fish are feeding in tight seams where standard parachutes tend to cant or ride unevenly.
