Abstract

The objectives of this study were to determine the fauna of Hydradephaga and to relate their assemblages in temporary ponds of Lonjsko Polje with respect to water permanence (hydroperiod) and shading of ponds by surrounding vegetation. A field survey was conducted in six different ponds in Lonjsko Polje Nature Park from May to December 2004. Aquatic coleoptera were collected using the semiquantitative method of sweeping with a D-frame pond net. Altogether, 341 specimens belonging to 29 species of Hydradephaga
were collected. The highest species richness was recorded for the Trebež pond, with 15 species of Hydradephaga recorded exclusively in this pond. None of the species were found in common in all the investigated ponds. It is observed that water beetles prefer more permanent ponds with a longer hydroperiod and open, less shaded habitats.
