Ephemerella invaria or the Light Hendrickson is an extremely abundant mayfly in the East and Midwest. Major hatches occur from early May in the South to late June in the North. These bugs take their time emerging which makes this pattern a “must have” when fishing this hatch. See also: Light Hendrickson classic, comparadun, parachute, spinner, or the Light Hendrickson Set. Tied on a Daiichi 1150 chemically sharpened scud hook.
