Intensifying agriculture is posing a threat to local biodiversity. Efforts of policy makers mainly go towards preservation of pollinators, but little go to preservation of natural enemies of pest insects like carabids (Carabidae). Semi-natural habitats like wildflower strips give the possibility to en-hance the functional biodiversity in agricultural landscapes by providing suitable conditions for beneficial arthropods. A goal is to design the composition of those wildflower strips in a way that they benefit not only pollinators but also support biological pest control from predatory ground beetles. Two types of agri-environmental schemes, a wildflower mixture and pasture land, in two physiographically different regions of Lower Saxony, Germany, are compared w.r.t their effect on diversity and abundance of carabids and wild bees (Apiformes). A field trial has been conducted in the summers of 2020 and 2021 by collecting arthropods and assessing the wildflower field con-ditions. These fields were in better condition in the region of extensive agriculture, due to lower fertiliser input, and significantly increased Carabid abundance and diversity there, while only in-creasing bee abundance. In the region of intensive agriculture wildflower fields barely affected abundance and diversity of carabids and wild bees although the base diversity and abundance was relatively high
