(De Geer, 1774)
Common furniture beetle, Common house borer, House borer
Anobium punctatum is a woodboring commonly known as the or house borer. are small beetles measuring 2.7–4.5 mm with , ellipsoidal bodies and a distinctive resembling a monk's cowl. The has a documented pattern in December in some , with females laying an average of 54.8 after a short preoviposition period. bore into and feed upon wood, making this species a significant pest of wooden structures and furniture.

Habitat
Wood-boring associated with wooden substrates; develop within wood. Laboratory studies used sapwood blocks of Podocarpus dacrydioides as -laying substrate.
Distribution
Widespread distribution including New Zealand (Auckland), and European islands (Corvo, Faial, Flores, Graciosa, Pico in the Azores). Global distribution as a pest of wooden structures.
Seasonality
in December observed in Auckland, New Zealand .
Diet
bore into wood and feed upon it. Specific wood preferences in natural settings not documented in available sources.
Host Associations
- Podocarpus dacrydioides - -laying substrateUsed in laboratory studies as sapwood block for ; not confirmed as
Life Cycle
pattern documented in some . females undergo short preoviposition period, followed by rapid -laying virtually complete by 15 days post-emergence. Average of 54.8 eggs per female. Adult female lifespan 24–31 days maximum. Larval development occurs within wood; specific duration not documented in available sources.
Behavior
Females lay rapidly following , with essentially finished within two weeks. Egg production correlates with female body weight in approximately 60% of individuals.
Ecological Role
Wood through larval boring activity.
Human Relevance
Significant pest of wooden furniture and structural timber. Commonly referenced in popular culture as evidenced by plush toy representations.

Reproductive biology
Laboratory studies show higher production (54.8 eggs/female) than field-collected females, suggesting potential -dependent or environmental constraints on in natural settings. Egg-laying distribution in laboratory was normal, not skewed or censored.
