Xylotrechus arvicola
Local name: Clyte apaisé
Clyte apaisé (Xylotrechus arvicola) is a longhorn beetle species characterized by its distinctive black and yellow banded pattern across its elongated body and antennae. As a wood-boring beetle, it plays a crucial ecological role in forest ecosystems by decomposing dead and dying hardwood trees, particularly oak and beech species.

Species Profile
Clyte apaisé (Xylotrechus arvicola) is a longhorn beetle species characterized by its distinctive black and yellow banded pattern across its elongated body and antennae. As a wood-boring beetle, it plays a crucial ecological role in forest ecosystems by decomposing dead and dying hardwood trees, particularly oak and beech species. Adults are active during summer months and are important pollinators of various flowering plants in forest clearings.
Xylotrechus arvicola faces severe population decline primarily due to habitat loss from deforestation and agricultural expansion, which destroys the old-growth forests it depends on for breeding. The species is also threatened by climate change affecting its host tree species and collection pressure from entomologists due to its rarity.
Key Facts
Habitat & Distribution
Clyte apaisé inhabits mature deciduous forests with abundant dead and dying hardwood trees, particularly favoring oak-beech woodlands with natural clearings. The species requires forest edges and sun-dappled areas where adults can access flowering plants for nectar feeding while maintaining proximity to suitable breeding substrates.
