[ O. chrysomeloides (Schrank, 1781)]

Comments: The species is commonly connected with large river valleys (Bunalski & Sienkiewicz 2012), and it is known in northern Poland (Lentz 1879; Bercio & Folwaczny 1979; Byk et al. 2016) and Belarus (Alexandrovitch et al. 1996). The larvae probably feed on hypogeous fungi (Byk et al. 2016). Its occurrence in local fauna (at the northern border of range) is possible: the nearest finding places are (Bercio & Folwaczny 1979) Lyck [now Ełk] and Allenstein [now Olsztyn], both in Warmian-Masurian region, northern Poland.
