Here's our most recent tying video, Les' Lemon Cahill, produced by Tim Flagler of Tightline Productions. The Lemon Cahill was designed by Les Shannon, who created it to imitate the yellow mayflies he found on his home water, the South Branch of the Raritan River, which was short walk from the fly shop he founded some 35+ years ago in Califon, NJ. Although Les intended the fly to imitate the Light Cahills and larger yellow and golden drakes, in smaller sizes it is a fine imitation of the Pale Evening Duns/Sulphurs that hatch so prolifically here in the Northeast.
Hook: Size 12 Mustad 94840
Thread: 6/0 Danville Tan or 6/0 Uni Light Cahill

Tie them in sizes #10 down to #18, to imitate a wide range of yellow colored mayflies that hatch from Northeast trout streams.
