The Kimballs Emerger was introduced to me by Drew Reid of Roaring fork Anglers in Glenwood Springs, Colorado. The original pattern omits the hackle and was tied on the front half of a standard dry fly hook. It is a very low floating midge emerger pattern and can be really hard to see because of its low profile. I altered the fly a bit by adding a few turns of hackle over the body to add floatation and visibility and changed the hook to the TMC 2488. I love this pattern for difficult midge hatches and especially in the late evening. The polypro loop wing and hackle add a tremendous amount of visibility and really float the fly well for such a small pattern.
