Three people are credited with this salmon fly; James Wright, PS Wilkinson and Mr Greenwell.   It is thought to have been originally tied by James Wright and then developed by Wilkinson and Greenwell.  The end result is a visually stunning fly, particularly the Temple Dog variant.  It is a very old fly and along with the Aglaia thought to be the first fly tied on an entirely silver body.  A very bright fly it had slipped out of use until one of Iceland’s best know fishers, Arni Baldursson revitalized it and has become increasingly popular ever since, particularly, the long-tailed and Temple Dog versions.  It is considered by many as one of the finest bright weather salmon flies around.
