Phylogeography, genetic structure and wing pattern variation of Erebia pronoe (Esper, 1780) (Lepidoptera: Nymphalidae) in Europe.

The distribution of genetic diversity within Erebia pronoe (Esper, 1780) populations in relation to biogeographic ranges is essential for understanding the processes of evolution, speciation and phylogeography in this species. A certain degree of genetic variability was expected because of the species' linkage solely to calcareous soils. These ideas were focused on the water ringlet E.

The invasion history, distribution and colour pattern forms of the harlequin ladybird beetle Harmonia axyridis (Pall.) (Coleoptera, Coccinellidae) in Slovakia, Central Europe.

The harlequin ladybird beetle Harmonia axyridis (Coleoptera, Coccinellidae) has invaded and established in Slovakia. Following unintentional introduction in 2008, the spread of the alien coccinellid was very fast. By the end of 2009, it was recorded across the whole country, and by the end of 2012 it was widely distributed and common in various habitats, particularly gardens, orchards and urban areas, where it was most frequent on trees.
