Ephemerella subvaria or the Dark Hendrickson is one of the season’s first major mayfly hatches. In the Northeast and upper Midwest the hatch usually lasts for 2-3 weeks. Parachutes are excellent patterns to use when the duns are hatching, usually in the mid to late afternoon. See also: Dark Hendrickson nymph, emerger, comparadun, cripple, and spinner patterns or the Dark Hendrickson Set. Tied on Daiichi 1190, Tiemco 100BL (barbless) or Daiichi 1180 (barbed) chemically sharpened hooks. Please specify barbed or barbless hooks when ordering.
