The factors that influence the alimentation preferences of the fish can be multiple and determine by various causes. The “fliers”, with their small hairy imitations, have without shadow of doubt a large responsibility on the feeding behaviour of trout and grayling, however it is lawful to suppose that the fish consider more savoury some insects because they are tastier to eat. If we consider the females of the Baetis scambus and of the Baetis muticus, as an example, we can notice that the trout often prefer them to any other insect, taking them selectively even if they are present on the water in a small number. From here, in order to gain the diffidence of our adversaries, we can use a small Light Cahill, an artificial very effective during the hatching of the B. scambus and B. muticus, but equally valid if it appears on the water the exuberant Heptagenia sulphurea

INSTRUCTIONS
I face the first step of the building process of the Light Cahill by fixing the hook into the vice jay and tying in on its shank the yellow thread, which I use for nailing, over the bend, a tuft of fibres stripped off from a large cream colour cock hackle. The tails so created must have a length approximately equivalent to the hook shank
I wax a short stretch of thread and I apply to it a pinch of cream colour polypropylene, to make a compact dubbing. The dubbing is then used to form the fly body along the rear two-thirds of the hook shank
From a blue dun and a cream cock neck, I select two hackles that have the fibres as long as the hook shank and I tie them in front of the body. From a grey flank feather of a mallard, I cut a small tuft of fibres and I tie it on the hook, placing it in the middle section of the front third of the shank and with the point of the fibres extended upwards. At the end of this implantation, the wings must have nearly the same length of the hook shank
|
|
With the apposite pliers, I wrap one after the other the two hackles around the front part of the hook, passing them behind and in front of the wing structure, so to create a fluffy collar
Next I cut off the surplus of the hackles and I create the fly head with some turns of the yellow thread, which is then finished with a whip-finish
|
A light layer of glue uniformly distributed over the head
will prevent to the thread to untie itself, increasing the resistance
of the Light Cahill
