Black Biot Krystal Flash PT

Thread: Black: Uni-thread 8/0
Tail/Wing Case: Black goose biot
Abdomen: One strand black krystal flash
Thorax: Black nymph dubbing
This pattern is a Ross Mueller creation and is an absolutely super fly throughout the year. however, it is particularly effective in the later winter months into spring when baetis emergence starts to occur. I typically fish it as a trailer to a larger nymph like a scud, hare's ear, etc. It's a simple tie using the biot tail and wrapping the krystal flash over it, then using the same biot as the wing case.
