Here's a pattern that I had tied for the Hatches article - but in a little bit more detail.
This is a fish-proof pattern. It looks delicate and will land gently, but after a good chomp by a fish it can be quickly dried with a false cast or two, and we're straight back into fishing. The wing, is a favourite of mine - TMC Aero-dry. Floats like a cork, easy to manupulate during tying and is just all-round perfect for post-parachute flies. I now use nothng else (except for vartying colour) when forming a post.
Hook: TMC 101 #14
Thread: 10/0 Roman Moser Powersilk, olive
Post: TMC Aero-dry, tan
Tail: Coq de Leon
Abdomen: Superfine, cream
Thorax: Fine hare
Rib: Waxed, spun thread
Hackle: Silver Badger
I use micrfibetts for the longer tails, but for short tails such as these, I think there is nothing finer than Coq de Leon. The colouring is very subtle.
It's a pattern with alot options. Change the colours and size and you can match alot of different upwings.
