March is the time of the year that we start to see the emergence of caddis fly here on the White river system and many others around the country. This is a time of the year that I always look forward too. The caddis fly brings about a feeding frenzy very unlike the slow deliberate rise forms associated with a emergence of may fly and midge. And in many cases the caddis will be the larger of the invertebrate species that are available to the fish in that particular water system.
Early season fish are hungry as many of the other food sources are not as yet in great abundance and it is not unusual for trophy fish to lose a great deal of caution that they will naturally attain as the season progresses. I have in my time caught many great fish during the caddis hatch. In the early season the majority of caddis will emerge during the hours of daylight. As the warmer weather takes over then the caddis emergence will take place during the dusk to dark period and at times way into the small hours of the morning. If you are out at such times you can really have a ball I can tell you, and again those big Browns just love to feed at such times.
The only main difference between species of caddis is size and color orientation so far as its relationship to a catching fish is concerned. You have a number of ways that you can deal with a rise to a caddis emergence from fishing pupae imitations to the adult winged insect. Some of the techniques that I use allow for all three stages to be fished at the same time.
The fly I am going to introduce to you is generally known as the green tail. This fly has some past historical aspects. It is one of the best soft hackles you will find to fish with during a caddis emergence regardless of the species. Back in the UK this fly is used when the Grannom sedge fly emerges, the female does carry a very distinctive green egg sac, which is why the fly is called the green tail. Regardless of the caddis species that is abundant at the time, you will not go far wrong with this fly. I have introduced some variations to this fly over the years and for that purpose I will give you three green tail patterns to tie. You may of course fish with more than one at a time by techniques from up stream dead drift to slow retrieve pulls and pauses.
Hook Size: From size 10 to 18. 12 and 14 being the most useful
Tying Thread: You may use brown, tan or green.
Tag: Fluorescent green or chartreuse.
Body: Natural hare fur from the mask of a hare or other dubbing to suit your species color.
Rib: Gold oval tinsel
Hackle: For the lighter shades brown partridge for the darker species English grouse. You may
also use a real soft webby hen hackle, from light ginger to dark ginger.
To tie the fly run a thread wrap from midway of the hook shank to the bend. Here build a not too large butt of the green thread. Take the length of gold oval tinsel and tie this in below the hook shank with three thread wraps. Build a neat dubbed body of the hare fur. Then make the 5 spirals of gold rib to the thread and cut off the excess. Take the Partridge hackle and strip all the base waste fiber off. Tie in the hackle by the tip and make 2 or 3 full winds. When done secure the hackle and cut off the excess. Whip finish and varnish.
The second fly pattern differs from the first by having a light ginger hen hackle palmered down the body of the fly before the Partridge hackle is tied in at the head of the fly.
The third fly pattern differs from the first only by the fact that it has a tail either from ginger hen or Partridge hackle.
