If you’re fly fishing for trout and grayling, you won’t get far without a good imitation of both mayflies and caddis. In the books and online there are literally hundreds of specific patterns and styles to choose from. Some of them we’ve featured here on the blog and some on our YouTube-channel, but I don’t think we’ve ever touched on the X-Caddis and the Sparkle Dun.

Caddis or sedge?

Sedge og caddis? I’ve been told that caddis is the common term in America, sedge the common term in the UK. I don’t really know and it doesn’t matter much, since I think most people know that both terms cover the same insect. Caddis is a very important food source for trout and grayling. They are abundant in both still- and running water and generally not as clean-water-dependant as many mayflies and stoneflies are. Some species grow quite large, so they also represent more protein pr. bite than smaller insects.

Caddisflies

The sight of a beautiful trout or grayling rising majestically to the surface inhaling an insect is the highlight of many flyfishers dream – the sight that drives us off to the water again and again.

Caddis nymphs

Like may fly nymphs and the nymphal- or larvae stage of any insect, the adult part of the life cycle is the shortest. The large mayflies can live for days, the smallest perhaps only for a hours. Caddis are generally the same – the larger species can live for several days, the smaller just a few days. After mating and egg laying they both die and become spent spinners – a stage off the life cycle the fish know well, since they are easy prey, unable to escape.

End of the dry fly season

The dry fly season coming to an end. But it’s certainly not over and the fishing can still be quite good. There are still insects on the surface – some that come from below and even some that come from above. An important food item for trout and grayling during the fall is sedges – or caddis.
