Fly Fishing Yellowstone - Beetles
(Carabidae)

Just to make sure there is no confusion, I want to mention that there are both
terrestrial and aquatic species of beetles in the Yellowstone National Park. This
is a huge group of insects. This is about the terrestrial beetle. These insects live
just about everywhere. The ones most important to anglers are the ones that
live near the streams, rocks, vegetation and plant debris.  

I'm sure you have heard of the Japanese beetle and the June Bug. Those are
just two of hundreds of different beetles that can fall into the water. Most of the
time it is not important to match a particular beetle. There is not enough of any
one species available for the trout to recognize them as such and there are not
enough of any one species that I have ever noticed for the trout to become
selective on a particular species.

Beetles come in all colors so I doubt the color is of great importance. If you
notice quite a few beetles of any type, color and size, along the banks of a
stream and the wind happen to be blowing fairly strong, it may be a good time to
try a beetle imitation. That is one of the times and situations I use a beetle
imitation. High wind will blow a lot of them in the streams (along with a lot of
everything else). If you happen to be in open areas or fields, you may prefer to
try a hooper imitation but if you are in a forest area, a beetle may possibly work
better when the wind is blowing strong.  

The other situation I use them is after a heavy rain. The high water can drain a
