Three guides for the systematic diagnosis of the insects directly along the rivers and streams. For the first time, the fly-fishing world has a perfect tool available to identify in a few minutes, or instantly, the aquatic insects belonging to the orders of Ephemeroptera, Plecoptera and Trichoptera. The guides are intended primarily for fly fishermen and for scientists working in the qualification of rivers, such as hydrobiologists, veterinarians and ichthyologists, who must frequently improvise if they aren't doing so already, even entomologists. The work consists of three guides (Ephemeroptera, Trichoptera and Plecoptera) designed to systematically determine the insects of these three orders. The system uses dichotomous keys complemented with photographs and drawings of the described morphological details. These keys are enriched with additional explanations which are in turn illustrated to simplify identification. But that's not all: where possible, tracking systems of "extreme simplicity" have been developed, as in the separation of Trichoptera families that are immediately recognizable by the characteristics of the case, or from particular features of the larvae do not build cases. One chapter is devoted entirely to the relationship between the Latin and English names of insects: all the insects that have an English name are identified along with the imitations that represent them; this link is extended to all the European species that may be of interest to the fly fisherman. With this information, it will be easy to associate any insect with its correct pattern in the English literature.
