Coffin Fly

Hook: Regular dry-fly hook, size 4.
Thread: White 6/0 (140 denier).
Tail: Three peccary fibers.
Underbody: White dental floss.
Body: White Antron yarn.
Wing: Teal flank feather.
Hackle: Golden badger.
Note: This pattern imitates the spent version of Ephemera guttulata. The original Coffin Fly was designed by Walt Dette and Ted Townsend almost 75 years ago. The Catskill green drake emerges between the end of May
 and the end of June. Some anglers fish the dun stage, but most elect to fish the evening spinner fall with the
 nearly all-white Coffin Fly. The pattern blends in among
 the natural insects, while the white body makes it easy
 to see in fading light.
