Color of Body by Dytiscidae: Variability and Possible Function
 HOKROVÁ, Monika
The aim of this thesis was to establish a photographic database of selected species of diving beetles (Coleoptera: Dytiscidae) and use image analysis to characterize the number and extent of colour spots. Altogether 52 species were analyzed. They were classified into fourgroups based on their environmental characteristics provided in the Catalogue of water beetles of Czech Republic. The results confirmedthe hypothesis that the colour of adult diving beetles is correlated to their habitat preferences.
