The research was carried out in the districts of Chisinau, Calarasi, Anenii Noi, Comrat and Gagauzia in 2022. 3 types of ants were identified - Lasius, Formica and Camponotus. The collections were made in different habitats such as alfalfa field or with other crops, meadow in the forest or forest or river bank. Dependence on the area and the identified ant species was observed. Species of the genus Camponotus ants were identified only in samples collected from central Moldova (Calarasi).

The species Lasius alienus and a species of the genus Formica have been identified in the alfalfa plains. Lasius emarginatus, being a forest species, was also identified only in the samples collected from this habitat.
