.............................Fly Fishing Yellowstone National Park
New Perfect Fly Midge Flies:
We have just received our first new "Perfect Fly" Midge Flies. The larva and pupa stages of the midges come in three colors - light green, cream and red. The adults or dry flies come in three colors - black, light green and cream. All of the midge flies are available in hook sizes 20 and 22.
We have found that these basic shades of color covers about 95% of all the midge larvae, pupae and adults we have found in trout streams in the United States. We have taken samples from streams from spring creeks, freestone streams and tailwaters throughout the nation during the past seven or eight years and this is the results.
Yellowstone Testing: We have tested these flies, or variations of them, mostly in the Madison and Firehole Rivers in Yellowstone National Park for the past three years. We have used them in several other streams but not to any frequent extent. We have taken trout on all three colors but cream seems to be the most effective color. In taking stream samples of the bottom in many places along these two rivers, we have found that cream is the most prevalent color. Even so, we have fished other colors we some success.
The most effective method we found was to use the pupa pattern dropped below a smaller dry fly such as a foam hopper. When I say "dropped", I should probably say "trailed" behind a dry fly. This makes it much easier to detect the takes. I will discuss the details of using these flies during the next three days.
