Oligoneuriella rhenana is one of the species which the fishermen of France call " manne" , as well because of its aspect of moth as for its impressive blossomings by the number of insects.

Ethology

Oligoneuriella rhenana is really a transitory : the duration of its existence (air) is particularly short, never not exceeding some heures.
In addition, its exclusively twilight manners, its spectacular aspect blanchâtre, and its blossomings, often make accept, which is not fishing, that it snows… in full August!

Localization

Oligoneuriella rhenana is an extremely widespread species in Europe, rather on the oxygenated and cold rivers.

Blossoming

From July to the end of August, in particularly massive blossomings, exclusively with fallen the day.
