Hook: Barbless dry fly 16 - 20 (I’ve used size 18 here).
Thread: Vevus 12/0 white.
Tail: Red Wool.
Body: Blue / Yellow Macaw Tail.
Hackle: Honey Dun Cock.
The blue and yellow of the body makes a kind of olive, and changes as the fly moves. It might make a great body for a Sparkle Dun. Hmm now there’s an idea.
Cheers,
A.
I suspect it would hang down though with a touch of oil it’ll float well enough. This kind of tail is common on the old fancy grayling flies (Red Tag, Witch series etc.).
I have a Macaw tail feather, but am out of honey dun hackle, the grayling fishing around here has not been very good since I moved here. I did catch one in AZ several years ago.
