In Russia this species is typically found in drier habitats including steppes. Nests have a soil mound (Zryanin & Zryanina, 2007). It is a temporary parasite of Lasius alienus (de la Mora et al., 2021; Janda et al., 2004; Seifert, 2018). It is a rare species in Greece (and vicinity), noted only from Macedonia, Thessaly, Thrace and Peloponnese. Its workers have been collected under stone in a mixed forest (Borowiec & Salata, 2021).
