Pre-emergent Sulphur

Fly: Ian Forbes, Photograph: Hans Weilenmann

Hook: To match the natural, usually #18 to #14 Mustad 9671 or similar
Thread: Color to match thorax
Tail: Dyed speckled flank feather from duck: teal, mallard or pintail
Body: Coloured wire to match natural, most often olive or brown
Wing: Aftershaft feather dyed colour of natural. Orange yellow for sulphur mayflies.
Hackle/Thorax: Dyed aftershaft feather wrapped around tying thread.
Tying notes: The fly pattern is meant to be worked slowly in the surface film or just under. Allow fly to dead drift with current and work it slowly by 'nodding' the rod tip
