Sprite S2175 size 14 hook. Uni-thread 8/0 grey. Few fibres of hackle for tail. Body of Hare-Tron gray dubbing ribbed with fine silver wire. Indian blue dun hen cape hackle. Note – ideally this pattern should have a grey seal fur body but I think the Hare-Tron dubbing adds similar translucence as seal fur. The fly is an old West Country hackled wet.
