Great Smoky Mountain National Park Insects Information
Over the past few years, I have mentioned and linked the Discover Life website as a
reference for the aquatic and other insects that are in the park. This past week, Mr. Charles
R. Parker, Research Aquatic Biologist, U. S. Geological Survey, was nice enough to let me
know that I should use the DLIA website. This one is for mayflies, for example:

We should use this site instead of the site I was
using. It's up to date on the list of species.

I haven't had the time to study this site very much but I can easily see it has many species of
insects not on the other site including some Angie and I found but couldn't officially confirm.
This site is very comprehensive and includes tons of information that should be of interest to
anglers. Although many of the species of insects in the Smokies may not be plentiful quantity
wise, the Great Smoky Mountains have a very diverse population of aquatic insects.

The most diverse group of organisms in the park will be the insects, and within insects the
order Coleoptera, or beetles, would be one of the most diverse.

Trout eat beetles when they fall into the water from the banks, bushes and grass along the
banks as well as the limbs of overhanging trees. One of the most common species found
along trout streams nationwide is the Japanese Beetle. They are an important terrestrial
insect food for trout, especially during the hot summer months. They become more important
to the trout and to the angler when there are few aquatic insect hatches. Like most of the
other terrestrial insects, you may encounter these insects up until the time it begins to frost.

There's over 28,000 species of beetles in the United States. There are aquatic species of
beetles and terrestrial (land) species of them. The aquatic variety is not very important in
most trout streams or lakes. The terrestrial variety is very important because they can
represent a good portion of the trout's food during the late Summer and early Fall.

High wind and heavy downpours can put a lot of them in the water quickly and when that
happens, the trout may focus on eating them. These beetles come in all sizes from tiny to
large sizes. We came up with a "Perfect Fly" Japanese Beetle fly that imitates what is
probably the most common and most important species of beetles for trout.

When a beetle falls in the water, it usually remains motionless. It tends to just ride the
surface. Maybe they go into a state of shock because the ones we have thrown in the water
always appear to just die, although we are certain they don't die quickly. You will find
Japanese Beetles crawling around on the banks, rocks, tree limbs and leaves, grass and
other vegetation near the streams in the park.  

In still or slow moving water with a smooth surface, it is usually best to fish the fly to individual
fish you can spot. If you are unable to do that, then the best method is to blind cast the fly to
likely trout lies near the banks where beetles are most likely to get blown or to fall in the
water. Most often, a down or down and across presentation works best in the slow water of
the pools. .

In fast moving water with a broken surface, such as pocket water that's typical of the
Smokies, you should present the fly using a upstream or up and across presentation. Again,
concentrate on likely spots where trout could be feeding or holding that are near the banks
with trees and other vegetation nearby.

We think our Perfect Fly Japanese Beetle Fly is the best imitation of a beetle ever developed
for trout. It's one of our best selling flies and anglers that try it, swear by it. They almost all
reorder and our fly tiers have a difficult time keeping us in stock.
