It permitted to collect II76 specimens including 86 species and 28 genera. The list of species observed is provided and most interesting species are discussed. In all, 61 unpublished mentions are made for 6 departments. Finally, a methodological reflection is undertaken. Despite a satisfactory overview of communities, there is a great variability in the catches by the use of Malaise traps. It could be explained by the localized temperament of Sphecids wasps and should be taken into account for future studies." . . . "Le Divelec et al. (2016)" . "2016"^^ .
