Tying Tuesday: Biot Stonefly Nymph

While on the river the other day, I noticed how slim the pickings are getting for my nymphs. I haven’t sat down to tie flies in far too long, and after watching this video from McFly Angler, I’ll need to add a few of these stonefly nymphs to my boxes. This is a fairly simple fly that should imitate any stonefly in most trout rivers.
