''Dinocras ferreri'' is a species of stonefly belonging to the family Perlidae. 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. Adults can reach approximately 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. ==External links== * * (Biolib ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dinocras ferreri」の詳細全文を読む スポンサード リンク
