Linkage between aquatic and terrestrial habitats aroused scientific interest on ecological subsidies, i.e. how the transfer of matter and energy between adjacent ecosystems can modify their own functioning. Freshwater ecosystems are widespread in agricultural landscapes, however the possible implication of aquatic subsidies is rarely considered. To fill this knowledge gap, we carried out a field work to study winged aquatic insects emergence and dispersal from twelve second-to-third order lowland streams in an intensive agricultural landscape in the northwest of France for one year. The contribution of aquatic insect emergence to ecosystem services in agricultural landscapes is discussed.
