This species is common in Mykolaiv ( Kotenko et al. 2011 ), but has a scattered distribution, found mostly around the Southern Bug River valley ( Dotsenko and Radchenko 2005 ; Nekrasova 2013 ; Sillero et al. 2014 ). We also observed this species along the entire valley of the Southern Bug River. Figure 6.
