Anobiinae is a of beetles in the Ptinidae, commonly known as death-watch beetles. The subfamily contains at least 45 and includes whose larvae bore into wood, earning them the name "woodworm" or "wood borer." Several species are economically significant pests, notably the common furniture beetle (Anobium punctatum), which damages wooden furniture and structural timbers. The subfamily has a distribution with members native to multiple zoogeographical regions.

Identification

Members of Anobiinae can be distinguished from other Ptinidae by their association with wood-boring larvae and characteristic . Specific diagnostic features vary by ; for example, the extinct Nicobium necrocrator exhibits sparse, inconspicuous elytral and rectangular, sharp pronotal angles. Detailed identification typically requires examination of genitalia and other fine morphological characters.

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

The has a broad geographic distribution spanning multiple continents. Individual show varied ranges: Ozognathus cornutus is native 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.

Diet

Larvae of numerous bore into wood; specific dietary details for most are not documented.

Life Cycle

Larval development occurs within wood, with larvae acting as borers. Specific developmental details vary by and are not comprehensively documented for the .

Behavior

Larvae are wood-borers, tunneling through timber and wooden materials. The "death-watch beetle" derives from the tapping sound produced by some , though this is not confirmed for all members of the .

Ecological Role

Larvae contribute to wood decomposition in natural . In human environments, some act as pests causing structural damage. The species Ozognathus cornutus has been associated with at least 41 -plant species; no adverse impacts on native biodiversity have been recorded for this species.

Human Relevance

Several are significant economic pests. Anobium punctatum, the common furniture beetle, damages wooden furniture and house structures. Wood-boring larvae of multiple species are collectively known as "woodworm" and can compromise timber integrity. The includes species that have spread through human activity, such as Ozognathus cornutus, which has expanded from its Nearctic origin throughout Europe and the Mediterranean.
