Hatches Made Easy:

Small Eastern Blue-Winged Olives - Duns and Spinners
(
Attenella species)

05/03/08

Dun:
Although the duns may drift a good distance (drying their wings from emerging
underwater) before departing the water, trout often continue to feed on the
emerging duns beneath the water. If you do not get satisfactory action on the
dun imitation, we suggest fishing an emerger pattern instead of the dry fly.
Imitations of the dun are normally a hook size 16 to an 18. How they got the
name "small" is beyond me.

Presentation:
Up or up and across presentations made in the seams of adjoining moderate to
slow currents and in the pockets behind obstructions may produce.

Spinners:
Like with the Easter Blue-winged Olives (Drunella species) I have never seen a
spinner fall of the Small Eastern Blue-winged Olives occur in the Great Smoky
Mountains National Park. I assume they fall after dark. Spinner falls occur just at
dusk over the ripples and runs of the river or stream in the Northeast. They are
not usually large scale spinner falls and may or may not provide good fishing.
Even there, we have only seen a very few spinner falls even where they are
large populations of this insects, such as the Delaware River. We have had very
little success fishing them.

Presentation:
If you happen to encounter a spinner fall of these mayflies, I would suggest that
you use a down or down and across presentation of the spinner imitation in the
areas below the riffles and runs where the females are depositing their eggs.
The fish we have found other places eating the spinners were in slow moving,
shallow water where they were easily spooked. The low light conditions just
before dark helps but you must be careful with the approach or at least that is
what we have experienced elsewhere.  Eddies and areas of slower moving water
below the riffles and runs may produce.
