Hatches Made Easy:

Small Eastern Blue-Winged Olives - (Attenella species)

05/01/08

I'll bet many of you thought I was through with Blue-winged Olives. At least most of
you probably hoped I was. When I first stated covering the Blue-winged Olives or
Baetis species, I informed you that we broke down what is included in the common
name Blue-winged Olive into
four categories. The reason is simple. There are
four groups of mayflies commonly referred to as Blue-winged Olives that
look and behave differently enough to require different imitations and/or
different methods of presentations.
The Baetis species of little swimming mayflies are one thing. They are bi-brooded
in the Smokies or have two hatches during the year. The "LIttle Blue-winged
Olives", which includes species of several other different genera that are also
bi-brooded, are different from the
Baetis species in many ways. The third group,
the "Eastern Blue-winged Olives" are quite different from both groups just
mentioned. They are larger crawler mayflies from the
Drunella genus and
Ephemerellidae family that emerge below the surface of the water in the summer
and early fall months of the year. Now we have what is usually called the "Small
Eastern Blue-winged Olives" or
Attenella species of the Ephemerellidae family, our
fourth and final group of mayflies that are commonly lumped under the
Blue-winged Olive name.
The only species of this mayfly that is officially listed for the Great Smoky
Mountains National Park is the
Attenella attenuata. The good part of this hatch is
that it occurs during the summer when many others have ended. On our hatch
chart, we show the hatch starting toward the end of June and continuing through
the first couple of weeks in July. The methods of fishing this hatch are not a great
deal different from fishing hatches of the
Drunella species we just covered. Both
are crawlers from the same family. However, there are differences worth noting.
