Some year’s ago on an Icelandic trout and char river our guide wanted to see our small flies. None of them were microscopic enough for his taste, so he gave a few size #20 “blood worms” of his own. The result was several dozen char and trout during that session – and a mental note-to-self to always carry red and black midges or buzzers in small sizes. The Blood Midge comes tied on a Daiichi 1270 hook.
