The Mini Leech is a creation of Landon Mayer. He ties it in small sizes in several colors - black, rust, purple, olive, etc. Fish often hit this fly very hard and a light tippet might result in some missed fish.

Fishing Hints: Fish the mini leech as a streamer stripping it (slowly) in the water column or fish it under a small indicator with twitches to cause motion.
Bend down the barb and mount the hook in the vice.
Starting behind the eye, lay a base of thread down the shank and return the thread to a point above the hook point.
Capture a piece of the Krystal flash on top of the hook shank and secure to below the hook bend. Return the thread to above the hook point.
Wrap the Krystal Flash around the shank forming a tag. Tie off the Krystal Flash and clip.
Cut an arrow in the end of the pine squirrel strip and attach it to the top of the hook shank starting at a point above the hook point. (Be sure the pine squirrel fibers lay towards the back of the hook.)
Tie on a Ostrich herl and lay a smooth base of thread from the pine squirrel to the eye of the hook.
