This variation of the Jigged Biot Stone is basically a modern epoxy biot stone fly nymph. It is a great pattern throughout the summer months on healthy water where a substantial stonefly population is present. Change up the color combination based on the bugs in your area. This brown color I like to fish as either a Giant Golden or a Small Western Stonefly. Blacks and gold/tans are great colors as well. With this specific pattern being a very heavy large fly I like to fish it in faster runs and deep holes as my first fly with a smaller emerger up above. No need to only through rubber legs. Sometimes a fly that is a bit more realistic can be just the ticket.
