This south European species was reported more than a century ago from Legnica in Lower Silesia ( Letzner 1874) and Ojców in Kraków-Wieluń Upland ( Eichler 1914), and recently from Upper Silesia ( Królik 2006, Greń et al. 2013), Wielkopolska- Kujawy Lowland ( Ruta et al. 2009), Pomeranian Lake District ( Ceryngier et al. 2016b) and Mazovian Lowland ( Bodzon & Ceryngier 2016, Ceryngier et al. 2016c). Its current range expansion and increase in numbers can probably be attributed to climate change.
