Sedge flies.  CADDIS.  Trichopterra.            

There are at least 33 recorded species of caddis flies in Shetland .

As with buzzers exact imitation is not important but matching approximate size, colour, stage of the hatch and trout inducing triggers are more important.

The Size of the caddis Species found in Shetland range from micro caddis at approximately 3 -5 mm in size for winged adults micro sedge to the large cinnamon sedge at 20mm or the even bigger buff sedge at 24-25mm.

Caddis have an interesting life cycle and are an extremely important food source of trout not just in Shetland but in many parts of the world.  

Most species of the caddis fly larvae build mobile homes that they carry around with them, however some species that have been recorded in Shetland are free swimming and others spin nets on the bottom of the loch in which to trap their prey.   

Depending on the species the case material is built from sand, stones, mud or vegetation.  Some of the cases are highly elaborate works of art in their own right.  

They live in various parts of the loch from rocky and stony shores, the stems of plants, sandy bottoms, in burns and in brackish lochs.

   They are a very interesting species in no small part because of their fascinating lifestyle and their cases which in some species are highly elaborate works of art. Trout also love them and their presence in the lochs opens the door to some explosive surface fishing and in part explains the success of some of the favourite patterns of Shetland anglers such as loch ordies, sedge hogs and muddlers.
