In 2001 and 2002 a survey has been carried out on several taxonomic invertebrate groups in five floodplain areas along the river Waal in the Netherlands. Studied groups are: aculeate wasps (Hymenoptera: Chrysididae, Crabronidae, Tiphiidae, Pompilidae, Sphecidae, Vespidae), Apidae s. l. (Hymenoptera), Carabidae (Coleoptera), Mollusca (only terrestrial species), Odonata, Orthoptera, Syrphidae (Diptera). The study focused on sand dunes, high river banks, grasslands and marshes. The aim of the study was to compare the investigated invertebrate groups in terms of betadiversity to determine their sensitivity for heterogeneity of floodplain ecosystems. The results have been analysed in combination with the faunistic database of EIS (European Invertebrate Survey) - the Netherlands. Based on this database, species were selected of which at least 5 % of their distribution is situated in the Dutch Rhine branches ('preferential species'). Considering their high diversity in floodplain areas, both in absolute numbers and in betadiversity, and high number of preferential species in the Dutch Rhine branches, aculeate wasps, Apidae and Carabidae seem to be the most suitable of the studied groups for assessment of the heterogeneity of floodplain ecosystems. In aculeate wasps and Apidae, the highest diversity occurs in high parts of the floodplains. In Carabidae and Syrphidae with aquatic larvae, the highest diversity occurs in low parts of the floodplains.
