Habitat

vary considerably across the . Some are associated with dead or decaying wood in natural forest environments. Others occur in human-modified environments, including buildings and structures with wooden components. The species Ozognathus cornutus has been recorded in both man-made and natural habitats, and was first detected in Greece from the Potala Palace in Lhasa. Some species are associated with specific plants, including Eucalyptus spp.

Distribution

Individual show varied ranges: Ozognathus cornutus is to the Nearctic zoogeographical realm and has spread throughout Europe and the Mediterranean region, with first records from Cyprus, Greece (Rhodes Island), and other Mediterranean localities. The Nicobium is represented in Baltic amber from the Eocene, indicating Paleogene distribution in European amber forests. The newly described genus Lhasella is known from Xizang (Tibet), China.
