The coloration pattern of 485 newborn sand lizards (Lacerta agilis Linnaeus, 1758) got by laboratory egg incubation was studied. The eggs were laid in terrariums by 109 pregnant females caught at two localities in the Samara Region (2011 - 2013 and 2015). The posterity of the females from the Togliatti locality exhibited two coloration morphs, typica exigua and immaculata-concolor, whereas that of the females from the Mordovo village (33 km from Togliatti, the opposite bank of the Volga river) had only one pattern, typica exigua.
