Beetles (Coleoptera) from seaside beach and dunes in the regions of Swinoujscie, Miedzyzdroje and Wiselka (Poland) located along the southern coast of the Baltic Sea.

A total of 118 species of beetles (Coleoptera) from 21 families were found from the end of May to the middle of September in Swinoujscie (in 2002, 2004, 2005), Miedzyzdroje (2000) and in Wiselka (2004). The fauna was collected using Barber's pitfall traps, entomological scoop and collecting dead and alive specimens of beetles.Coleoptera were studied in the following habitats: 1 km along sandy beach, white dune with the plant community Elymo-Ammophiletum arenariae, and grey dune with the plant community Helichryso-Jasionetum litoralis.The most numerous beetle families were: Staphylinidae (23 species), Chrysomelidae (14 species), Coccinelidae (12 species), Curculionidae (11 species), Elateridae (10 species) and Scarabaeidae (9 species). The beetle assemblies of sandy beach and dunes included xerophilous, termophilous, halophilous and psammophilous species. The most interesting of them with respect to dunes and seaside beach were: Aegialia arenaria (Fabricius), Coccinella undecimpunctata Linnaeus, Coniocleonus hollbergi (Fahraeus), Hoplia parvula Krynicki, Hypocaccus metallicus (Herbst), Negastrius pulchellus (Linnaeus), Omonadus floralis (Linnaeus), Onthophagus taurus (Schreber), Otiorhynchus atroapterus (De Geer), Oxythyrea funesta (Poda), Philopedon plagiatus Schaller, Phylan gibbus (Fabricius), Sitona grisea (Fabricius), Typhaeus typhoeus (Linnaeus), Tytthaspis sedecimpunctata (Linnaeus), Xantholinus rhenanus Coiffait.<br />Three species are placed in the Red List of Threatened Animals of Poland: Typhaeus typhoeus (Linnaeus) (NT - nearly threatened category), Hoplia parvula Krynicki (LC - least concern) and Otiorhynchus atroapterus (De Geer) (EN - endangered category).
