Hatches Made Easy:

Eastern Blue-Winged Olives - (Drunella species)


The Eastern Blue-winged Olive is just another blue-winged olive in the eyes of
many anglers. For the most part, that is just fine but there are some important
differences worth nothing. The Eastern is a species of the
Drunella Genus of the
Ephemerellidae family. Those of you familiar with the Western Green Drake may
be surprised to know that the Eastern Blue-winged Olive is in reality just a small
Western Green Drake.
For the most part, these Olives hatch in the Summer and early fall months when
other hatches in the Smokies are few and far between. These mayflies don't
hatch in large quantities either, but they do provide some activity when other
mayfly hatches are slack. These are the species known to exist in the Great
Smoky Mountains National Park.

Note: These are fat
little bugs unlike the
slim BWOs that are
swimmers. They
also have 3 tails
and a hind wing
unlike the other
BWOs species. This
one was found
under a leaf on a
tree on Little River
near Elkmont in
June. The image
was taken by
putting a rock and
the dun on my leg. It
amazes me why at
times mayflies won't
fly off and other
times it is impossible
to keep them from
it. This one was
about a hook size
