2.    Little Brown Stoneflies
3.    Quill Gordons
4.    Blue Quills
5.    Little Black Caddis
6.    Hendricksons/Red Quills
7.    Little Short-horned Sedges
8.    American March Browns

9.    Sculpin, Minnows (Streamers)






Change in Insects List Above:
I made a few changes this morning in the above insect list. I added the American March Brown mayfly and
the Short-horned Sedge, or caddisfly. Normally, I would be removing Quill Gordons from the list at this time
but hatches are running a little late this year due to the cold weather. There should still be a few Quill
Gordon hatches taking place for at least another week.


This Week's Featured Trout Food - American March Browns
This is a another mayfly with a common name that creates confusion with anglers. If you fish for trout in both
the eastern and western states, you will notice there are two March Brown mayflies. The ones in the west are
the true March Browns and those in the east, including the Smokies, should have "American" added to the
name to help reduce the confusion. We run into this problem all the time at Perfect Fly because western
anglers sometimes order American March Browns and eastern anglers often order March Browns. There are
big differences.

The American March Browns are
Maccaffertium vicarium species. The March Browns are Rithrogena
morrisoni, hageni
and other less common Rithrogena species. As you can see, they are completely different
mayflies.

Those that have been familiar with this mayfly for a few years may need to also know the
following
: The American March Browns, the ones in the streams of the park, were reclassified by the
scientist a few years ago. Not only did anglers get the mayflies confused, the scientist also did. Until DNA,
mayflies were strictly classified by their appearance and other physical characteristics. The American March
Brown used to be the
Stenonema vicarium. There also used to be a Stenonema fuscum species. It was
called the Gray Fox.
Well, guess what? They were both determined to be the exact same species. A Gray
Fox is the same mayfly as the American March Brown. Due to the mistakes they discovered, they eliminated
the
Stenonema fuscum and changed the genus name of the American March Brown to Maccaffertium.

I recently read a new Southern Trout magazine article written by Harry Murry, a well noted Virginia fly shop
owner and author, where he provided a hatch chart for the Shenandoah streams. It shows both a March
Brown and a Gray Fox with different hatch times.

Mr. Murray, if you had checked on anything to do with mayflies in the last ten years you would know there is
no such thing as a Gray Fox.

The American March Browns should start hatching in the Smokies any time now. In the Smokies, anglers
often confuse them with the less familiar Hendricksons which usually hatch about two weeks prior to the
American March Browns.

By the way, something all anglers should know about hatches is that although the exact time hatches occur
can change from year to year with average weather changes,
there is never a change in the order in
which the insects hatch. It is always the same.
