Abstract

Abstract In winter 2019, an excursion to the central and eastern parts of Georgia was conducted, focusing on arboreal species and other carabids overwintering under bark or at the base of trunks. Other habitat structures were also investigated. The work was done as part of ongoing studies in preparation of a new checklist of Georgian Ground Beetles and to contribute to the faunistic as well as ecological knowledge base for the main natural areas of this country. Forty-three taxa were recorded. The arboreal species Dromius agilis (Fabricius, 1787), the plant-dwelling species Demetrias imperialis (Germar, 1823), and Paradromius suturalis (Motschulsky, 1844), and another six species (Microlestes corticalis (Dufour, 1820), M. fissuralis (Reitter, 1901), M. fulvibasis (Reitter, 1901), M. luctuosus Holdhaus in Apfelbeck, 1904, Pterostichus leonisi Apfelbeck, 1904, and P. strenuus (Panzer, 1796)) are new for Georgia. In some sites, the number of recorded specimens under bark, in litter, or in the upper soil was very low, probably due to specific climatic conditions (e.g., very low humidity). It is supposed that in these areas, most of the individuals reside deeper in the soil during periods of low activity or hibernation. The number of Dromius individuals overwintering under bark near the stem base increased with altitude. The relevance of special survey methods in the winter for ground beetles is emphasized.
