Common Names: Great blue-winged red quill
Scientific Name: Timpanoga hecuba

Duns closely resemble green drakes , but hatch later in the summer. Hecubas are locally important, and where hatches occur they are welcomed by fly anglers. That's partly due to the season--mid to late summer--when so many of the hatches are small bugs like tricos . What fly angler can resist a large insect?

Nymphs live in stream sections with moderate current, and are seldom important to anglers. Hatches of duns can be very productive, however. Dun and emerger/cripple patterns are useful, and trout may be selective on one phase or the other. So observe carefully and determine which one is best to imitate.
