| Summary: | The Baltic Sea coast typical habitats formed by a mild sea climate are characterized by infertile and saline sands, predominant western winds and are peculiar only to this region. The aim of the study is to investigate the beetle (Insecta, Coleoptera) fauna of seashore habitats of Lithuania, beetle distribution in different habitats. The material was collected during the study period of 2008–2010 in 10 different localities of Curonian Spit. Research territories were selected so that investigated plots covered all habitats of the Baltic Sea coast. After analyzing and generalizing the material collected in the Baltic seashore habitats a total of 1206 beetle species belonging to 70 families, or 32.7% of all known Lithuanian beetle fauna were determined; 52 beetle species of 16 families were recorded first time for Lithuania. Cryptocephalus ochroleucus Fairm. is a new species in the Eastern Baltic region and in Fennoscandia. The old-growth mixed forest distinguished by the greatest species number (174 beetle species) and grey dunes overgrow with lichens, mosses and Poaceae exibited the lowest species number (20 beetle species). The open habitats of the Baltic Sea coast were dominated by termophilic psamophilic beetle species. Stenotopic (89 species) and halobiontic (27 species) beetle species were typical only of open seashore habitats. Halobiontic species were the most abundant in the grey / white dunes with Leymus arenarius. |
