: From May till September 1998, more than 80 pitfalls were placed on 17 different gravelbanks in the summerbed of the river Meuse to get an idea of the invertebrates occurring in this extreme habitat. The grasshoppers that could take most advantage of the gravelbanks, were Oedipoda caerulescens, Tetrix subulata and T. tenuicornis. Also some species were caught that are common everywhere: Chorthippus biguttulus, C. brunneus and C. parallelus.
