Osmoderma lassallei
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Osmoderma lassallei faces severe population decline due to the loss of ancient oak forests and veteran trees essential for its larval development. The species requires hollow trees with accumulated wood mould, making it extremely vulnerable to forest management practices that remove old or dead trees. Urban development and agricultural expansion have fragmented remaining suitable habitats, while climate change may alter the microhabitat conditions within tree hollows that larvae depend upon.
Habitat
This hermit beetle inhabits hollow cavities of ancient deciduous trees, particularly old oaks, where larvae develop in accumulated wood mould and decaying heartwood. The species requires veteran trees with substantial trunk hollows, typically found in old-growth forests, ancient parklands, and traditional wood-pasture systems.
