Earlier gerbarny collecting confirms finding of a look in vicinities of Nyankov (Novogrudsky district of the Grodno Region). According to literary data the look was known in vicinities of Rusotin (Korelichsky district the Grodno Region), Kopylya, Nesvizha, Novogrudka, Svislochi (the former Grodno province) and Minsk.
