Eastern Pale Evening Duns
The Eastern Pale Evening Dun is called a Sulphur by most of the anglers that fish
the Smokies. It exist in many of the tailwaters in the South where it is also usually
called a Sulphur. It isn't a Sulphur. It is an Eastern Pale Evening Dun but is just one
of many confusing problems that common names bring about. There is one thing
that helps in this particular case. The Eastern Pale Evening Dun and the true
Sulphur are very similar.

For those that want to know, the Eastern Pale Evening Dun is the
Ephemerella
invaria.
The true Sulphur is the Ephemerella dorthea. There are important
differences in color, hatch times, habitat and methods of imitating them. The
Eastern Pale Evening Dun mayfly is found in the Eastern U. S., and in some
Mid-western trout streams.

The body of the Sulphur is more of a true sulphur color than the Eastern Pale
Evening Dun. The Eastern Pale Evening Duns body is a tannish, yellow color.
The sulphur is also a hook size and sometimes two hook sizes smaller than the
Eastern Pale Evening Dun. These mayflies usually hatch late in the afternoon
from about 4:00 to 7:00 P. M. They hatch approximately two weeks earlier than
the Sulphur Duns. Both are currently hatching in Great Smoky Mountains National
Park. Most of what you see are the Eastern Pale Evening Duns.

Generally, you will find Eastern Pale Evening Duns in moderately flowing water.
These mayflies like faster moving water than the Sulphurs they are often
confused with. Most of the time you will find them at the ends of long runs. Large
pockets located within fast water areas may hold Sulphurs.

Neither the Eastern Pale Evening Duns, or the Sulphurs are plentiful in the Smokies.
They are crawler nymphs and only exist in isolated areas of the streams. However,
when they are hatching, they can be very important with regards to catching trout
and they certainly shouldn't be overlooked.

The Eastern part of the Pale Evening Dun name is added because there is also a
Western Pale Evening Dun that is almost always just called Pale Evening Dun. It is a
completely different mayfly that's not even close to being similar to the Eastern Pale
Evening Dun. For those that want to know, the Western Pale Evening Dun is the
Heptagenia elegantulata and Heptagenia solitaria species. As you can see, it isn't
even in the same family as the Sulphur or Eastern Pale Evening Dun.

Now I admit, that's a lot to know or keep up with as it is expressed above, so here is
as simple of a way as I know how to put it. In the Smokies and many local tailwaters
such as the South Holston and Clinch Rivers, both the Eastern Pale Evening Duns
and the Sulphurs exist. There are differences but there are also so many similarities
and often the differences are irrelevant. You do not need to concern yourself about
the Western Pale Evening dun unless you are purchasing flies and want to make
sure you get the right ones. That can be a problem.

When you are thinking Eastern Pale Evening Duns, you should think about the fact
they hatch in faster water - not fast water but moderate water near the ends of fast
water. Sulphurs hatch in slower water that is in the pockets and on the slow side of
current seams. Eastern Pale Evening Duns are usually a hook size 14 or 16 (mostly
16) and Sulphurs are a hook size 18.

Gulf of Oil Warning:
Yesterday, I forget to mention one other thing that could become of utmost
importance about the oil spill that is not though about except for those that happen
to live along the coastline. If the northern U. S. Gulf Coast gets hit with a hurricane
this summer, damages to many, many other species will occur. The oil will be
pushed up into all the bays, rivers and deltas that are anywhere near the point of
landfall. The damage will extend much farther than what the tidal influence is
affecting. The areas on the right side of the eye of the storm will be most affected.

I hope and pray this doesn't happen this summer, but if it should it will drastically
increase the damage from the oil. This would affect all the inland species of fish,
birds and wildlife along the coastline and for miles inshore. Don't worry about it
though. Just be stupid enough to think that BP will pay for all the damage and it
probably want bother you at all.
