Hydropsyche Larva

I believe fish react to tiny details which set an edible item apart from a piece of debris floating in the water column.

A big part of this is the correct presentation of the fly; the appropriate size, shape and colour and tiny details like the legs.


The silhouette of insect legs is very characteristic. Even from a long distance these tiny legs can be identified. This, in my mind is a prime trigger for fish.

The fly shown is an upside-down tied variation of the famous pattern by Oliver Edwards. It fish’s very well and is a lot of fun to tie. You need a pheasant tail feather; take a few fibres off the the main stem by ripping them at a 90 degrees angle from the main stem. The fibre roots make nice little feet. These are also known as Veli Autti legs.

The problem is how to angle the fibres sort of 90 degrees from the body of the fly. This is solved by «pulling» the fibre into a softer material. The fibre is held by the tying thread in the softer material. The remaining fibre is clipped off.

So this «soft material» is the basis for the fly. You can use all sorts of materials for that task. One very common solution is latex strips in 3mm width offered by various manufacturers. Make sure it is not too thin. I am very happy with a product called “Nymphskin” made by Virtual Nymph Products in England.

USD = upside-down – why upside-down?

Generally, flies are fished with hook point on the underside of the fly. Upside-down is when the fly is tied so that it fishes with the hook point upwards. The Hydropsyche Larva is easier to tie this way. You can of course use the same type of hook in regular fashion and have the legs on the same side as the hook point, under the hook eye. For fishing, it makes little or no difference.

Fly Tying at Skålestrømmen

Fly tying classes are part of the inclusive packages we offer at Skålestrømmen. You can learn to make these all these flies yourself. Tying materials and tools will be supplied if cannot bring your own.

The fly shown works very well in Skålestrømmen (and around the world). There are of course many other, mostly more complicated types of flies that also work, but we like it simple and efficient.

However, do not worry. A selection of flies is included in the  fly fishing packages we offer. You can also buy flies and materials in our flyshop.
