Résumé :
|
Volume 43 covers the Plecoptera. They are mostly unknown in Italy, not only to the general public, but often also to fishermen, naturalists, enthusiasts and amateur and professional entomologists. Inconspicuous, short-lived and difficult to detect, they are important indicators of water quality and the abundance of fish, because the presence of these insects in a stream is itself evidence of a certain integrity: one must realise that the Plecoptera are a major food source for salmonids and therefore occupy a key role in the ecological chain of mountain waterways and sub-mountain a book to identify them.
