This Week's Featured Trout Food - Eastern Pale Evening Duns
This mayfly is another one that is confused with other mayflies thanks to confusing common names. In the
southern states, the Eastern Pale Evening Dun is usually called a Sulphur. Because common names
designate whatever insect one desires it to designate, I can't say that calling an
Ephemerella invaria a
Sulphur is wrong, but it is contrary to what the majority of anglers call it as well as all books on aquatic
insects. It is also very confusing because it indicates the
Ephemerella dorothea dorothea, or true Sulphur, is
the same mayfly and it isn't. By the way, there are two dorothea's in the name. I didn't make typo error.

In both the local Clinch River tailwater and the South Holston River tailwater, the Eastern Pale
Evening Dun is incorrectly called a Sulphur by the local anglers.
It is also half of the reason the
so-called Sulphurs hatch almost year-round on the South Holston and for several months on the Clinch
. The
reason is simple. The appearance of the two mayflies is similar and both Eastern Pale Evening Duns and
Sulphurs exist in the streams as well as the Smokies. The population that exist in the Smokies is much
smaller but not necessarily less plentiful in the isolated areas of the park these two mayflies exist in. In other
words, the streams of the park have only a few sections that hold these mayflies and those sections that do,
have more Eastern Pale Evening Duns than Sulphurs. They prefer slow to moderate flows, not fast pocket
water. Just for example, the moderate sections of Hazel Creek and Cataloochee Creek have plenty Sulphurs
and Eastern Pale Evening Duns.

By the way, those that know very little about mayflies also confuse the yellow colored Light Cahill
with both the Sulphur and Eastern Pale Evening Dun.
The difference in these mayflies is huge. They
are different types of nymphs. The Light Cahills are clingers and exist in the fast water in plentiful quantities
and the Sulphurs and EPEDs are crawlers that exist only in isolated sections of the freestone streams in the
park. Their behavior is as different as daylight and dark.

Since I'm mentioning confusing names, I might as well point out
the reason "Eastern" is added to the
name is because the Pale Evening Dun, found in many western trout streams, is an entirely
different mayfly.
They are Heptagenia elegantulata and solitaria species, which of course, is a different
family.

To try to help solve the confusion between the Eastern Pale Evening Dun and the Sulphurs which are both
called Sulphurs in the Clinch and South Holston Rivers, let me point out the easiest way to tell the difference
is the color. EPED's are more of a tan color and the Sulphurs are a true sulphur color. There are other
differences. The EPEDs are generally slightly larger and prefer slightly faster water. The Sulphurs are
slightly smaller and prefer the slower water.
This is a male Eastern Pale Evening Dun. The big tomato colored eyes will distinguish the
males from the females of both the EPED and the true Sulphur. The females have very small
dark colored eyes and the males the big red eyes.
This is a female Eastern Pale Evening Dun Spinner. This was shot on the South Holston
River. Notice the long tails and legs of the spinner. You can also see the tannish yellow color
as opposed to what would be a more sulphur color of a Sulphur - sulphur as in the color of the
chemical sulphur.
