Abstract

The insects of the Late Pleistocene mesofauna in fossil soils within the Yansky Plateau in the Ulakhan Suullar site (the right bank of the Adycha River) and the Batagayka Thermokarst Basin were studied. In field studies, a macro-entomological method has been successfully applied. It has great potential, and therefore, its wider introduction into research practice is needed. The article presents some dominant species of the Late Pleistocene communities: weevils (Curculionidae), pill beetles (Byrrhidae) and ground beetles (Carabidae). It has been established that the ecological proximity of the insect fossils discovered by us, indicates that the dry tundra-steppe (the dry tundra and steppe tundra) prevails in the Late Pleistocene environments, since the pill beetle Morychus viridis is a true tundra-steppe indicator. The analysis of national and foreign literature shows that the knowledge about the insects in Siberia, including Yakutia, is not comprehensive. It has been established that paleo-entomological findings provide the most reliable information when reconstructing the natural conditions of the past.
