Summary
Bostrichidae, commonly known as auger beetles or false powderpost beetles, is a family of beetles characterized by their wood-boring habits. They have numerous species worldwide, with variances in habitat, size, and economic impact, particularly as pests in wooden structures and stored grains.
Physical Characteristics
Typically 2-24 mm in length, with some species reaching 52 mm. Head is often downwardly directed and hidden by the thorax except in subfamily Lyctinae and Psoinae. Some species, such as Bostrychoplites cornutus, have large, distinctive thoracic horns.
Identification Tips
The head of most auger beetles cannot be seen from above. Pay attention to size and the presence of distinctive thoracic horns in specific species like Bostrychoplites cornutus.
Habitat
Most species are found in and around wood, including living or dead trees, seasoned lumber, and woody fungi. Some species are associated with stored grain.
Distribution
Over 570 species in 90 genera worldwide; approximately 70 species in 25 genera are found in specific areas, including Australia and the United Kingdom. Some exotic species are established in new regions due to trade.
Diet
Primarily wood-borers that attack living or dead wood; some species are associated with woody fungi or stored grain.
Ecosystem Role
Play a significant role in decomposition and nutrient cycling by breaking down wood in various habitats.
Economic Impact
Some species are pests of timber and stored grain, leading to economic losses in the wood and agricultural industries.
Cultural Significance
Certain species, such as Bostrychoplites cornutus, are imported as larvae in wooden bowls marketed as 'ethnic souvenirs'.
Evolution
Fossil records extend to the Cretaceous period, with ancient specimens found in Burmese and Charentese ambers from the Cenomanian age.
