May 16 is a unique holiday for many fly fishermen, as the grayling season begins in Slovenia at that time. There are already many different groups of insects along and in the water, temperatures are rising and grayling is very active after spawning in the early spring months. This time we are writing about five groups of artificial flies that we prefer to use for grayling fishing, as they are very successful.

Grayling may not grow very large, but they are picky. Larger specimens are difficult to catch, so fishermen appreciate them and love to fish. In Slovenia, grayling fishing is allowed only with an artificial fly tied on a barbless hook. Occasionally grayling also grabs some other types of baits. Fishermen often catch them while coarse fishing for whitefish, and in rare cases they also grab a small metal lure or other smaller types of artificial lures.

As a target fish, grayling are tackled only with the technique of fly fishing and with an artificial fly. Not all artificial flies are equally successful. We will fish the most experienced and old grayling well only if we have some of the following groups of artificial flies in the box: smaller hackled flies (dry and wet version), CDC flies, and smaller nymphs. It will pay off if we prepare even the smallest versions of the mentioned groups of artificial flies on hooks sizes #18, #20, or even #24 and a wide range of their color shades (from gray, brown to black). We prefer to fish with the artificial flies described below.


In fact, all types of CDC flies will be good, they just need to be small enough and the right colors. Fratnik’s fly is much loved by the world’s fly fishing fans because of its efficiency and ease to tie. Its author is a Slovenian, Marjan Fratnik, so we can be especially proud of it. With it, he fished grayling and trout in his native Soča area in NW Slovenia, and elsewhere. In the Slovene-speaking world, the fly is known as Fratnikova puhovka (F-fly).

Spinner and duns

Spinners and duns are very efficient, especially in grey-blue colors (e.g. BWO or similar). Grey flies of this kind also imitate mosquitos, and black-ones follow the shapes of ants. The possibilities are wide and limited only by the fisherman’s imagination.

Pheasant tail

Its author, Frank Sawyer, fished trout with it, but the hungry grayling will not refuse it as well.

Hares ear

If we decide to fish with a nymph at greater depths or in a stronger current, where the fly must sink quickly and reach a certain depth, we will often prefer to reach for the hare’s ear rather than a pheasant tail. This classic nymph, similar to Sawyer’s pheasant tail, mimics many aquatic insects in the larval stage.


Gammarus nymphs are most often tied in light brown tones, and the olive color is also extremely successful.
