New KISS Bug Series - Part 53
Small Western Green Drakes (Flavs)
I made an error in the above information in the introduction article to the Small Western Green Drakes. I
had them listed as clinger nymphs and they are crawler nymphs. I knew better. I just copied the wrong info
down and didn't check it. The "Flavs", as they are called, prefer moderate currents. They cannot live in still
or slow moving water.
Many of the streams in Yellowstone National Park offer the perfect habitat for them. In fact, you will find
them in most of the streams in the park although not always in large concentrations.
Like many crawler nymphs, when they get ready to hatch, they move out of the faster water to nearby
slower water. This may be calm pockets in pocket water or the slow side of current seams in smoother
water. Trout feed on them with ease during this movement. It's by far the best time to catch trout on an
imitation of the nymph. The nymphs emerge in the surface skim and it is very easy for the trout to eat them
when they are accenting to the surface to hatch.
A few days prior to the hatch and in the mornings during the hatch prior to their emergence, you can use
the standard up and across presentation using a strike indicator. Fish the our "Perfect Fly" Small Western
Green Drake Nymph near the bottom on the slow sides of the current seams, in calmer pockets behind
boulders and in the slower water along the banks in fast moving pocket water. You will need to weight it
fairly heavily using non-toxic weight.
