Body Smolt-blue Krystal Flash over red floss band (wrapped)
Wing White calf hair (divided)
Hackle Brown hackle (2 feathers)
How to tie it
Mount a standard dry-fly hook and start red thread a third of the way back from the eye.
Tie in a bunch of white calf body hair as an upright wing, one shank length tall, then post and divide it into two wings with figure-8 turns. Stack the hair first — calf hair is crinkled and will not sit evenly otherwise.
Wrap back to the bend and tie in a bunch of brown hackle fibres as a tail, one shank length long.
Tie in smolt-blue Krystal Flash at the bend and wrap it forward to the midpoint.
Wrap a band of red floss at the midpoint, then continue the Krystal Flash forward to the wing so the red band sits centred in a flashing blue body.
Tie in two brown hackles behind the wing and take two turns behind and two in front.
