Reconstruction of the Genesis of Faunal Assemblages of Insects (Insecta, Ectognatha) of the Raised Bogs of the Belarusian Lakeland

Abstract

A putative scenario for the formation of insect assemblages of raised bogs of the Belarusian Lakeland is proposed. Early Holocene, when groups of chortobiont species trophically associated with cotton grass, as well as sphagnicoles and species associated with pine, were formed, is proposed as the time when insect assemblage formation began. The next stage occurred in the Atlantic period, when the relics of periglacial fauna and flora, including phytophages of ericaceous shrubs, apparently moved to the bogs. The formation of the core of insect assemblages with a set of characteristic stenobiont species probably ended in the subboreal period, since the main spectrum of ecological niches for the extant insect complex was present by this time.
