A fly that worked well for me in the past:
Hook: TMC 102Y size to match the real insect.
Tail: Black hackle fibres
Body: Black Super-fine-dry-fly dubbing.
Wings: 2 white hackle-tips, tied upright and separated with tying thread.
Hackle: Black cock hackle.
A wee bit of grease and the fly is ready to rock-and-roll.
Cheers, Hans
