Click Beetles (Coleoptera, Elateridae) in Agrolandscapes of Northwestern Russia

Abstract

A total of 44 species of click beetles (Coleoptera, Elateridae) were recorded in the agricultural landscapes of Northwestern Russia; 23 species were found in various crop fields. Species of the genus Agriotes Eschscholtz, 1829 were the only ones that were recorded in all the examined biotopes. Cluster analysis showed the Elateridae complexes in cultivated lands to be different from those in adjacent habitats (field margins, forest edges, and natural meadows). Within the agricultural landscapes, the highest species richness of Elateridae was recorded in the biotopes adjacent to crops. Much lower abundance of click beetles was observed on loamy soil with excess humidity.
