Sprite S2499 size 16 hook. Uni-thread 8/0 olive. Few dun hen fibres for tail. 4 strands peacock Krystal Flash for body. Few strands of black Krystal Flash for wing case. Thorax of Vicuña brown dubbing from their dry fly collection. Note – this pattern is my version of a Rick Hafele creation detailed in Dave Hughes book, ‘Nymphs for Streams & Stillwater’ – a book no serious nymph fly ftyer should be without.
