The Zen of the Biot Wing Caddis

The biot is a highly versatile material that has become one of the most important components of my fly tying repertoire. In the midst of all of today's technologies and mind numbing levels of information the simple biot keeps me focused on whats most important. Tie lots of flies, and focus on the most simple and basic materials. Make it a daily ritual, and practice it like a discipline. The biot is the epitome what's right in the world today. As in any material, fly tying or other, if you put your mind into a resourceful state of being, doing, and making anything is possible with...VERY LITTLE.

Over the years my fly boxes are paired down and much simpler. I carry less and less flies every season, and I use less materials to create what I need.

 Biot Wing Caddis
Hook: TMC 531 14-26
Body: SLF Spikey Squirrel
Rib: Clear Mylar
Wing Case: Dyed Biots, (left and right wing feathers)
Legs: Double knotted Pheasant tail
Thread: Veevus 14/0 or 16/0
Hackle: Dusky gray, or medium gray
Antennae: Stiff hackle fibers or Coq De Leon
Under Wing: TMC Aero Wing Dry Fly medium dun

Tie in clear mylar rib and dub in SLF to create a hothouse carrot profile. Now tie in TMC Aero Wing Dry Fly for under wing material. Tie in two sets of knotted legs on either side of the body three quarters up the hook shank just below thorax area.

Take one biot from each corresponding feathers one on right side one for left side. Rib should be facing up on wing case on both sides. Clip an angle profile of the caddis wing and chamfer the bottom edge by cutting an opposing angle. The cupping of biot faces in towards the body forcing all of the body materials into a neat contained channel under the biots. Slip both biots over the hook shank and tye them in three quarters up the hook shank in thorax area. Push down with your index finger on top of wing case this wil help seat and level out the wings.
Clip off both tag ends of the biots. Now tie in your hackle collar. Leave enough space behind the hook eye to tie in the set of antennae.
 



This has been a highly versatile fly for me over the years, it may not be the easiest to master but with a little focus and practice it can be a killing fly that will save you on the river when all else fails.

Slow Water Caddis Emerger

 The Caddis emerger is a very important part of the trouts diet. During this life stage the Caddis is especially vulnerable to the elements and is easy prey thus making it very attractive to these very energy conscious fish. The insect is just about ready to break free of its nymphal shuck and the count down for its launch sequence begins with a few wiggles. I have always been looking for a great surface fly that mimics these little beauties. For a few years now I have gotten a lot of use of this little emerger pattern that tends to out fish most of my other emerger patterns even when there is no discernible hatch. This is a great pattern for super finicky Brown trout. I have fooled many fish with this pattern and with the right combination of materials it is a pattern that stays floating even in fast water for a long time. With the use of TMC's Aero Wing material (extended shuck) the fly is a great floater. The fibers are not only fine but hollow keeping the fly float...

CB's Japanese Beetles

Walker an Ohio Photographer.  Debbi is a talented outdoor photographer who loves to take pictures of insects, animals, and landscapes and often shoots photography around the Mad River and Cedar Bog. In the heat of the summer many fish hunker down during the day and will pass up the occasional Caddis, midge, or ant floating overhead. Often fish conserve energy for a larger more nourishing food item. During the summer months fish want to conserve energy and exert themselves only for the most significant meal.    This is called the “Pounds Per Meat Law” again the least amount of energy is expelled for the most nourishment possible. This should be the mid-summer mantra for both fishers and fish!  Large ants are another food item that fish will come off of the bottom for during the midday sun and heat. Japanese Beetles are one of those items on the surface menu that will spark a fishes interest when nothing ...

The Four Season Emerger

Fellow fly fishers ask me all the time what kind of “staple” emerger pattern I use so I decided to share my “Four Season Emerger” pattern. The following is a simple emerger pattern that I use season after season. This fly is very durable, very convincing, and the TMC 212Y hook is a perfect canvas for this style fly. The Four Season Emerger Thread: Veevus 14/0 Hook: TMC 212Y 14-22 Wing: CDC natural or desired tint Body: Dyed Peacock quill Dubbing: (Thorax) Beaver Belly w/guard hairs Legs: Knotted dyed Pheasant tail (double knotted) Varnish: SH Hard as Nails You can tie this up as a midge, mayfly, or even caddis imitation depending on your proportions and material selections. First create a body on a TMC 212Y sizes #14-22 by winding a stripped and dyed peacock quill. Varnish with 2 coats of SH Hard as Nails. After your bodies have dried tie in some knotted pheasant tail. Notice the two knotted strands, two legs on both sides of the hook. Dub over your thr...
