Leeches are an important food source for all things “fishy” subsequently most Fly-Fishers have a go to pattern that they use.Mine has always been a very basic Mohair Leech as it’s simple to tie and fishes well.Fishing Leech Patterns on both Rivers and Lakes can be done in any number of ways and all methods are effective.You can hang underneath a Strike Indicator and Nymph them, trail a leach pattern behind a larger streamer and strip them back or fish a couple leeches in different of combinations and see which works.A popular method on Alberta’s Bow River is to tie a “light” Leech pattern and drop it off the bend of a Foam Stonefly or Hopper Pattern.Leach Patterns are versatile,effective, and impressionistic,meaning your quarry might be eating them for a number of reasons on top of looking like leeches.

Why The Simi Seal Leech ?
My fishing Clients from Arizona always raved about the Semi Seal Leech and we would fish them with excellent results.For whatever reason I did not completely embrace this pattern even after moving to Arizona.The Mohair Pattern seemed to work fine so I just never bothered tying The Simin Seal Leech until this year. John Rohmer’s Simi Seal Leech is even easier which makes it faster to tie.It’s also just as effective as my old “go to” !Best of all it requires one Material which is Simi Seal Dubbing,throw a Bead on it and you are set.It is just as effective as more elaborate patterns and with the variety of colors you can cover the whole gauntlet of what you can use it for.Normally we are tying it in sizes #8-#10 on a Mustad 9672 nymph hook. Colors I like are Black,Brown,Tan and white.These colors cover the gauntlet on which fly can represent which are Leeches,Baitfish,Crayfish,Damsel,Dragon and Stone fly nymphs.Checkout JohnRohmer’s Video below have fun tying.Click Here for Materials.
