Rosalia alpina (Linnaeus, 1758) (Coleoptera: Cerambycidae) – specie rară în fauna Republicii Moldova

The paper includes data on species of the genus Rosalia from collection of the Museum of Entomology, Institute of Zoology, Moldova State University (MSU). The species Rosalia alpina is present in the fauna of the Republic of Moldova, while the species Rosalia coelestis occurs in the Russian Far East. The study was based on materials accumulated through the authors’ own observations conducted during the period 2018–2025, as well as on specimens from the insect collection of the Institute of Zoology, MSU. The biology, ecology and habitat preferences of the species R. alpina are discussed. The presence of two small populations of this species in the „Plaiul Fagului” Nature Reserve and the „Codrii” Nature Reserve was confirmed. The obtained results together with an analysis of the relevant literature prove the importance to create and maintain strictly protected areas, with the preservation and conservation of ancient trees. Preserved and sustainably managed natural forest habitats are essential for the maintenance and restoration of rare saproxylic invertebrate populations, including the species Rosalia alpina.
