Distribution
Dinocras ferreri is present in France, Italy, and Switzerland. The species is restricted to the southern edge of the Alps, and it can also be found in small parts of the northern Apennines.
Description
Adults can reach approximately 40 millimetres (1.6 in) in length and can mainly be encountered in small waterways.
The basic coloration of the body is pale brown, including the head and legs. The wings are membranous and translucent, with evident brown veins. At 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 develop. The flat larvae usually stay under rocks just emerging from the waters.
