Grasshoppers, crickets (Orthoptera) and earwigs (Dermaptera) of Tovačov gravel pit (central Moravia, Czech Republic): New locality for several thermophilous species in anthropogenic secondary habitat

Abstract Study of Orthoptera and earwigs was conducted in Tovačov gravel pit in 2014. We have recorded 18 species of Orthoptera and 3 species of earwigs. The most significant recorded species are Cepero’s ground-hopper (Tetrix ceperoi), pygmy mole cricket (Xya variegata), Italian tree cricket (Oecanthus pellucens) and riparian earwig (Labidura riparia). Tovačov gravel pit poses the northernmost locality of T. ceperoi and X. variegata in the Czech Republic and the northernmost known locality in Moravia for O. pellucens. For the L. riparia, we present a founding from Tovačov together with another finding from Olomouc vicinity, which is currently the northernmost locality within Moravia. Our findings display recent spatial expansion of some thermophilous species. Moreover, we emphasize importance of (post)-industrial areas as secondary habitats for specialised endangered species.
