Summary
Anobiinae, commonly known as death-watch beetles, are a subfamily of wood-boring beetles within the family Ptinidae. They feature elongate cylindrical bodies and include many genera, with some species being notable pests.
Physical Characteristics
Body elongate cylindrical; pronotum often gibbous; antennae usually with 3 terminal segments elongated, sometimes also enlarged; head retracted below pronotum when disturbed; pronotum usually with distinct side border.
Identification Tips
Look for the gibbous shape of the pronotum and the structure of the antennae, particularly the elongated terminal segments.
Habitat
Wooded areas, often associated with decaying wood or wooden structures.
Distribution
World-wide, with representation in North America.
Diet
Larvae are wood-borers, feeding on wood as they develop.
Life Cycle
Life cycle involves larvae boring into wood, followed by pupation and emergence as adult beetles.
Reproduction
Information not provided; general patterns include egg-laying in or near wood.
Predators
Natural predators are not specified; may include various insectivorous birds and mammals.
Conservation Status
Not assessed; generally regarded as pests in certain contexts due to their wood-boring behavior.
Ecosystem Role
As wood-borers, larvae play a role in decomposition and nutrient cycling in ecosystems by breaking down wood materials.
Economic Impact
Certain species like the common furniture beetle (Anobium punctatum) can cause significant damage to wooden furniture and structures, categorizing some as pests.
Cultural Significance
Pests like Anobium punctatum have a historical presence in homes, influencing wood treatment and building practices.
Collecting Methods
- Trapping with pheromones
- Hand collection from infested wood
Preservation Methods
- Drying specimens
- Using ethanol or isopropyl alcohol for preservation
Evolution
Previously classified under Anobiidae before being reclassified to Ptinidae.
