Lepture bossue
Cortodera humeralis
Cortodera humeralis, commonly known as the hump-shouldered longhorn beetle, is a distinctive cerambycid beetle characterized by its robust build and prominent humeral swellings on the elytra. This species plays an important ecological role as both a wood-boring insect in its larval stage and as a pollinator of various flowering plants during its adult phase.

Species Profile
Cortodera humeralis, commonly known as the hump-shouldered longhorn beetle, is a distinctive cerambycid beetle characterized by its robust build and prominent humeral swellings on the elytra. This species plays an important ecological role as both a wood-boring insect in its larval stage and as a pollinator of various flowering plants during its adult phase.
Cortodera humeralis faces severe population declines primarily due to habitat loss and fragmentation of its specialized mountain forest environments. The species' restricted range and specific ecological requirements make it particularly vulnerable to climate change and human disturbance of alpine ecosystems.
Key Facts
Habitat & Distribution
This beetle inhabits mature deciduous and mixed forests, particularly those with abundant dead or dying hardwood trees that serve as larval host material. Adults are typically found on flowers in forest clearings and edges during their brief reproductive period in late spring and early summer.
