Flying dytiscids were trapped in an agricultural landscape with wetlands in different successional stages and in two urban landscapes with young wetlands. We compared the faunas in air and in water. Hydroporus and Agabus were the most frequently trapped genera in air. Most species were trapped near water in the agricultural landscape, species characteristic of later successional stages were common in air and dominated in water. In the urban landscapes, species were mainly trapped far from water and species known to colonise new waters were common in air and in the youngest waters. Overall, females and immature adults were more common in flight catches during April-July than during August-October. Our results indicate that urbanisation would result in a less diverse fauna, but may lead to an assemblage dominated by species that are infrequent in agricultural landscapes. To obtain a rich wetland insect fauna, a wide range of wetland types is required at the landscape scale.
