Stimulators have become one of my favorite searching patterns over the past several seasons. Prior to last year I tied quite a few in an assortment of body colors; yellow, olive, peacock, black, tan and red. The heavily hackled attractors in size 16 and 14 performed admirably on the various Colorado streams, but the color that clearly distinguished itself as a necessity in my fly box was the light yellow version.
My devotion to the yellow stimulator began on the Lake Fork of the Conejos River on July 18, 2016. I experienced a day of frustration on the main stem of the Conejos, and in an act of despair, I diverged on to the tiny Lake Fork tributary. Initially I was surprised by an abundance of refusals to a pool toy with a yellow body. I was encouraged by the sudden attention, but it took me a fly change or two to solve the riddle. I eventually opted for a size 16 stimulator with a light yellow body, and the fish rewarded me for my persistence. During my time on the main Conejos I observed quite a few yellow Sallies and small golden stoneflies, so the effectiveness of the small yellow stimulator was not entirely unexpected.
Not wishing to suffer another day of frustration on the Conejos River on July 19 prompted me to drive to Elk Creek, a tributary seventeen miles downstream from the Lake Fork. Guess what I discovered? Amid a fairly steady emergence of yellow sallies and golden stoneflies the size 14 yellow stimulator accounted for twenty trout, and quite a few were above average size for the small tributary.
On July 20 I accepted the challenge of the Conejos River once again despite high flows and memories of a day of futility on July 18. The sought after pale morning dun and green drake hatches never materialized, but guess what salvaged my day? A fairly heavy afternoon emergence of yellow Sallies and two sizes of golden stoneflies prompted me to once again resort to a size 14 yellow stimulator, and it proved to be a winning choice. The yellow attractor contributed eight fish to my count, and enabled me to enjoy a respectable day on the difficult main stem of the Conejos.
When I reviewed my posts from July 2016, I entered a reminder on my fly tying to do list to produce an adequate quantity of new yellow stimulators, and in early February this became a reality. I refreshed my memory of the tying steps with an excellent YouTube video, and then I sat down at my tying bench and produced twenty yellow stimulators. Half were made on size 16 hooks and the other half were attached to a size 14. Golden stoneflies and yellow Sallies cannot come soon enough.
