Rosalia longicorn — size comparison — facts and sources

The Rosalia longicorn is associated with old forests, particularly beech woodland. Females lay eggs in bark crevices and damage, and larvae develop inside wood over several seasons.

Adults emerge in summer and are active on sunny days. Their life on exposed trunks is much shorter than hidden larval development. Preserving old trees and suitable dead wood allows the next generation to complete its development.
