Little Yellow Quill Nymphs
The Little Yellow Quill nymphs are clingers that stay hidden most of the time until they
migrate to the shallows to emerge. The nymphs prefer fast to moderate current up
until they emerge. A week or two before the hatch begins they move to the slower
water of small pools and the heads, edges and tailouts of larger pools and other
shallow water areas to emerge. They also may hatch from the very ends of the long
runs and riffles where the water is relatively shallow. They are a hook size 16.

If the weather is still warm when they first start to hatch they usually hatch late in the
day in the very late afternoon. During October and November, especially during the
higher elevations, they may hatch early in the afternoon, as early as 2:00 P.M.

The Little Yellow Quill clinger nymph imitation should be fished up and across on a
dead drift with a small amount of weight added a few inches above the fly. They are
much more effective just prior to a hatch but you can take trout on the Little Yellow
Quill nymph year-round.

If the water is low and the trout very spooky, and it often is in the summer and early
fall when they hatch, you may need to use a down and across presentation. We also
suggest a long, light leader with a six or seven X tippet under these conditions. You
want to allow the fly to swing from the ends of the riffles into the slow water.
