First record of Rosalia Alpina (Linnaeus 1758) (Coleoptera, Cerambycidae) in Prunus Avium (L.) (Rosaceae)

Abstract:

The use of Prunus avium (L.) as habitat of the legally protected longicorn Rosalia alpina (Linnaeus, 1758) is recorded for the first time. The observations took place in a dying cherry tree located in a garden of a coun-tryside land belonging to the municipality of Asteasu (Gipuzkoa). The presence of adults mating and looking for oviposition sites, exit holes, and one larva inside a dead branch suggest that R. alpina is able to complete its life cycle in the cherry tree. Two other saproxylic species, Cerambyx scopolii Fuessly, 1775 and Ampedus pomonae (Stephens, 1820), were found inside dead branches. In the region of the study area, R. alpina had only been previously recorded on Fagus sylvatica L. trees. Therefore, further research is suggested to determine the impor-tance of other tree species like alternative habitat and their role in the conservation of R. alpina.
