These flies, tied by Buchner, imitate the common burrower mayfly (Ephemera simulans) and other mayfly species, including a great red quill (Timpanoga hecuba) shown in the inset photo, in either the adult or subimago/dun forms. The fly on the left is an extended-body brown drake pattern, and the right is a parachute hare’s ear pattern. Photos by Jay Buchner.
