Speckle-wing Quills: (Callibaetis species) Duns

Dun:
Since the duns fly away very quickly, especially or bright, clear days, fishing the dry fly
may not be very effective. Colder, cooler days may cause the duns to stay on the
surface for a few more seconds than normal. Many times, it is more effective to
continue to fish an emerger pattern or a nymph pattern than the dun imitation.

Presentation:
The dun imitation should be cast on as long of a leader and as light of a tippet as
practical, preferable in front of a feeding trout. In still waters, casting to cruising trout
commonly called “gulpers” is an art within itself.
