Since 1985 we have been monitoring the state of beetle coenosis in selected localities in the Protected Landscape Area Latorica (South-eastern Slovakia). We found more than 820 species of beetles (Coleoptera) of selected localities. Phytophagous species from the Curculionidae and Chrysomelidae families ware dominated. Indicator species are important in assessing habitat changes. They also found several rare species in the area: Bagous petro, Scarites terricola, Minyops variolosus, Polystichus connexus, Choleva paskoviensis, Chaetocnema sahlbergi, Otiorhynchus porcatus. Several habitats have changed over 30 years. Changes in habitats are mainly: drying of water surfaces, changes in sand habitats, etc.
