Identification of Meligethes species and their frequencies in adult samples collected at different localities in Central and South Moravia (Czech Republic, 2009–2011) was based on comparisons of morphometric and colour characters and on differences in male and female genitalia. M. aeneus, M. viridescens, M. subaeneus, M. atratus, and M. coracinus were recorded throughout the observation period, while M. nigrescens was recorded just in 2009 and 2011, M. carinulatus and M. maurus in 2010 and 2011. M. aeneus was the most frequent species of all compared samples (2009–2011). Of the accompanying species, M. subaeneus and M. viridescens were markedly more frequent in this study. Considering high resistance of M. aeneus to esteric pyrethroids, it could be helpful to distinguish among the individual Meligethes species occurring in field samples intended for laboratory testing.
