Hatches Made Easy:
Great Smoky Mountains - Little Brown Winter Stoneflies
The Little Brown Winter Stoneflies of the Taeniopterygidae Family (sometimes
called Little Black Stoneflies) and the Nemouridae family (sometimes called
Forestflies) are very important to anglers fishing the Smokies during the late
winter and spring months. These two families of stoneflies are very difficult to tell
apart and that is why I have grouped them together. For the angler’s
purposes, the main difference is the color. Some are brown and some look
almost black. Some have a red tint to them and are called "Little Red Stoneflies"
but they are not very plentiful in the Smokies. It would be almost impossible to
identify any of these stoneflies in the field even down to the family level. Since
the behavior of both families is very similar, the very minute physical differences
in the two families make no difference to anglers.
Technically, there is no Little Black Stonefly, only the Little Brown Stonefly. This
can be confusing to anglers simply because many of the Little Brown Stoneflies
are black. Furthermore, some of the dark brown stoneflies look black.
Although you certainly don't need to know how to identify them down to the
species, these are know species of the Taeniopterygidae Family of stoneflies
that exist in the Smokies.
Taeniopteryx maura (reclassified as Taeniopteryx burksi)
These are the know species of the Nemouridae family of stoneflies.
As I have previously said, the stoneflies are one of the easiest of insects to
imitate. The Little Brown Winter Stoneflies are no exception. Like all of them,
they crawl out of the water to hatch. That means you only need to know how to
imitate the nymphs and the female adults when they deposit their eggs.
Unlike the Little Winter Stoneflies of the Capniidae Family, or Snowfles as they
are called, these are plentiful and easy to find.
The Nemouridae family of “Early Brown Stoneflies”, are small brown or black
colored stoneflies. They are typically springtime emerging stoneflies.
The Taeniopterygidae family consist of a group of medium sized, dark bodied
stoneflies. Emergence times range from winter through spring for most species.
They usually hatch from noon until mid afternoon during winter and early spring
