The Red Tag is an artificial fly originally designed as a dry fly for grayling and trout in the north country of England.

The fly pattern, when introduced into Australia, particularly Tasmania, became extremely successful and popular for brown trout and remains today as one of the most essential flies for Australian fly anglers.

The Red Tag was originally designed by Martyn Flynn from Worcestershire, England in the 1850s as a dry fly for grayling.

[2] red The typical Red Tag is tied with a body of peacock herl, a tail of red or crimson wool, and a red cock's hackle (actual color of hack is reddish brown).
