This species is present in France, Italy and in Switzerland, countries where it is restricted to the southern edge of the Alps and small parts of the northern Apennines.

Adults can reach approximately 40 millimetres (1.6 in) of length and can mainly be encountered in small waterways.

The basic coloration of the body is pale brown, including head and legs. The wings are membranous and translucent, with evident brown veins. At the rest they are folded over the body. The head has threadlike antennae and yellow spots on the sides. The abdomen is yellow, with two cerci.

Both sexes are winged, but the adults are bad fliers and never leave the running cold waters where the larvae have developed. The flat larvae usually stay under the rocks just emerging from the waters.
