Beetles (Coleoptera) are the largest, originally terrestrial, insect order with a complete metamorphosis. They invaded the aquatic environment to secondarily, thanks to adaptations allowing storing and keeping the oxygen underwater. Aquatic beetles occur in three of the four sub-orders (Adephaga, Polyphaga, Myxophaga). They live on all continents except Antarctica, however the highest proportion of the diversity is concentrated in the tropics. The beetles are characterized by huge variability of morphological features as well as ecological preferences. About 12.500 aquatic beetle species are now known worldwide, more than 350 species from 15 families are reported from Slovakia. Among them Dytiscidae and Hydrophilidae are the most numerous.
