Yellow Evening Dun
Late-season evening dun
TroutSurface
A pale yellow-bodied upwing dry for the late-season evening hatch of small yellow duns on Irish limestone rivers — a September fixture on rivers like the Liffey when the bigger summer olives have thinned out.
Fish this when
September evenings on limestone and lowland rivers, when small pale-yellow duns are on the water and fish are rising steadily in the last light.
Why it works
Colour match matters most in low evening light against a pale sky — the yellow body reads correctly where a standard olive dun would not.
