The Caddisfly

The caddisfly insect is a cornerstone in the world of fly fishing and it plays an important part in the life of salmon and trout. From early spring to late in the season juvenile salmon and trout will meet the caddisfly insect in its many forms and shapes – Adult salmon and trout will also meet the caddisfly throughout its life in the river system, and during period of caddisfly hatching flies that resembles the caddisfly in shape, colour and/or behaviour can become top choice the fly box. Sometimes it could be a dry fly like our Monster Tube Caddis ™ a small hitched fly like the V-FLY ™ or a classic wet fly like the Blue Charm that with it`dull dark appearance becomes much more efficient in some Nordic rivers during August when caddisfly hatching is in progress

Here we have gathered some images of the big Caddisfly found in so many clear rivers in northern Norway
