    Fourteen predatory species of ladybirds (Coleoptera: Coccinellidae) were collected from May to October 2008 from mountain ash (Sorbus aucuparia) infested with the scale insect Chionaspis salicis at 31 localities in the Ore Mountains, northern Bohemia, Czech Republic. Ch. renipustulatus, usually a rare species, made up 85% of the individuals collected (1690). Other abundant species were Coccinella septempunctata, Calvia quatuordecimguttata, Adalia bipunctata and A. decempunctata. The invasive alien Harmonia axyridis was present but made up less than 1% of the individuals collected. Niche overlap between pairs of ladybird species measured in terms of the coefficient of community, Morisita’s index and cluster analysis showed that microhabitat preferences were similar and hence the possibility of competition was high in two pairs of congeneric species(Chilocorus and Calvia). Larvae of Ch. renipustulatus were abundant from mid-June through August and were still present in October.
