Abstract
New data on the occurrence of ladybird beetles in the eastern part of the Baltic Coast of Poland are presented. Studies were carried out between 2012 and 2017 along the Baltic coast from Krynica Morska to Białogóra. We found 44 species of Coccinellidae. Ten of the recorded species (Clitostethus arcuatus, Scymnus haemorrhoidalis, S. limbatus, S. abietis, S. auritus, S. rubromaculatus, Stethorus pusillus, Hyperaspis concolor, H. reppensis, Platynaspis luteorubra) are reported for the first time from the investigated area. Two of them, C. arcuatus and S. pusillus, are new for the whole Baltic Coast region of Poland. The recorded contribution of the invasive Harmonia axyridis to all ladybird individuals was relatively low (12.7%).
Highlights
Owing to a few common species, the ladybirds (Coleoptera: Coccinellidae) are a relatively well recognized beetle group
In 1882 reported by Helm from Gdańsk, but in more recent times not mentioned from the eastern part of the Baltic Coast
Of the 44 species of Coccinellidae recorded in the eastern part of the Baltic Coast in this study, 10 have not previously been reported from this region
Summary
Owing to a few common species, the ladybirds (Coleoptera: Coccinellidae) are a relatively well recognized beetle group. Reported from the Wielkopolska-Kujawy Lowland (Ruta et al 2009), Mazovian Lowland (Ruta et al 2009), Lower Silesia (Ruta et al 2009), Małopolska Upland (Borowski 2015), Eastern Beskidy Mts (Szczepański et al 2015), Masurian Lake District (Wigry National Park) Rather common in Poland and locally very abundant, it has not previously been reported from the Baltic Coast region.
