The Bostrichidae are a family of beetles with more than 700 described species. They are commonly called auger beetles, false powderpost beetles, or horned powderpost beetles. The head of most auger beetles cannot be seen from above, as it is downwardly directed and hidden by the thorax. Exceptions are the powderpost beetles (subfamily Lyctinae), and members of the subfamily Psoinae.

Dinoderus brevis

Bostrychoplites cornutus has large, distinctive thoracic horns, and is found in parts of Africa and Arabia; it is often imported to Europe as larvae in African wooden bowls ("ethnic souvenirs") .[1]

The Dinoderinae comprise a subfamily of the beetle family Bostrichidae. There are five to seven genera. They live in wood. Some species are known as pests of wood-based and other stored products.Genera include:








Heterobostrychus is a genus of beetles in the family Bostrichidae, the horned powder post beetles. Like other beetles of the family, these live in wood, often inflicting significant damage on timber and other wood products. This genus can also be found in crop plants such as cassava, potato, coffee, oilseeds, and pulse crops.Heterobostrychus aequalis, known commonly as the lesser auger beetle, trank borer, black borer, and kapok borer, is a notorious pest of many wood products. It has been found in plywood, furniture, wooden toys, wooden clogs, and carvings.These beetles are transported from their native range in tree products and introduced to other regions in timber shipments. Several species have easily established in new areas, particularly those with warm climates, as they do not tolerate cold. H. aequalis is now found on six continents in regions within 40° of the Equator.Heterobostrychus brunneus is most common in bamboo.The adult Heterobostrychus is 1 to 1.5 centimeters long. The head is tucked back within the thorax and not visible from the top.There are six known species.Species:

Heterobostrychus aequalis

Heterobostrychus ambigenus

Heterobostrychus brunneus

Heterobostrychus hamatipennis

Heterobostrychus pileatus

Heterobostrychus unicornis

Lyctus (beetle)

Lyctus is a genus of powder-post beetles in the family Bostrichidae, being present on all continents except Antarctica.

Lyctus brunneus

Lyctus brunneus is a species of beetle in the family Bostrichidae. It is a member of the subfamily Lyctinae, the powderpost beetles. It is known commonly as the brown powderpost beetle or brown lyctus beetle. Today it is distributed worldwide but it was probably originally native to the Neotropical region.Like other powderpost beetles, this species lives in wood.

Lyctus carbonarius

Lyctus carbonarius is a wood-boring beetle in the family Bostrichidae (formerly in the family Lyctidae, which is now a subfamily of Bostrichidae), commonly known as the southern lyctus beetle or lyctid powderpost beetle. It is a serious pest of hardwoods including ash, hickory, oak, maple and mahogany and can infest many products in the home including hardwood flooring and structural timbers, plywood, furniture, tool handles, picture frames, baskets and ladders. Timber can be infested in one location and then be transported large distances by ship, after which the beetles can emerge and spread the infestation to new areas.Lyctus planicollis LeConte, 1859 is considered a synonym of the species of Lyctus carbonarius.


Polycaoninae is a subfamily of horned powder-post beetles in the family Bostrichidae. There are at least 2 genera and 20 described species in Polycaoninae.

Powderpost beetle

Powderpost beetles are a group of seventy species of woodboring beetles classified in the insect subfamily Lyctinae. These beetles, along with spider beetles, death watch beetles, common furniture beetles, skin beetles, and others, make up the superfamily Bostrichoidea. While most woodborers have a large prothorax, powderpost beetles do not, making their heads more visible. In addition to this, their antennae have two-jointed clubs. They are considered pests and attack deciduous trees, over time reducing the wood to a powdery dust. The damage caused by longhorn beetles (family Cerambycidae) is often confused with that of powderpost beetles, but the two groups are unrelated. The larvae of the Cerambycidae are white, straight and generally flat-headed, whereas those of the Bostrichidae are white and C-shaped.


Ptinidae is a family of beetles in the superfamily Bostrichoidea. There are at least 220 genera and 2,200 described species in Ptinidae worldwide. The family includes spider beetles and deathwatch beetles.There are three main groups in the superfamily Bostrichoidea: Bostrichidae, Anobiidae, and Ptinidae. These have undergone frequent changes in hierarchical classification since their inception. They have been treated as a single family, three independent families, the two families Bostrichidae and Anobiidae, or the two families Bostrichidae and Ptinidae. More recent literature treats these as the two families Bostrichidae and Ptinidae, with Anobiidae a subfamily of Ptinidae (Anobiinae).Spider beetles are so named because they look like spiders. Some species have long legs, antennae that can seem like an additional pair of legs, and a body shape that may appear superficially like that of a spider.

Deathwatch beetles are named because of a clicking noise that two (and possibly more) species tend to make in the walls of houses and other buildings. This clicking noise is designed to communicate with potential mates, but has historically caused fear of impending death during times of plague and sickness.


Rhyzopertha is a monotypic genus of beetles in the family Bostrichidae, the false powderpost beetles. The sole species, Rhyzopertha dominica, is known commonly as the lesser grain borer, American wheat weevil, Australian wheat weevil, and stored grain borer. It is a beetle commonly found within store bought products and pest of stored cereal grains located worldwide. It is also a major pest of peanuts. The first documentation of wheat infestation by R. dominica was observed in Australia. R. dominica are usually reddish brown to dark brown in coloration, vary in sizes, elongated and cylindrical when viewing through a cross-section.


Scobicia is a genus of horned powder-post beetles in the family Bostrichidae. There are about 11 described species in Scobicia.


Stephanopachys is a genus of horned powder-post beetles in the family Bostrichidae. There are about 15 described species in Stephanopachys.


Trogoxylon is a genus of beetles in the family Bostrichidae. They are members of the subfamily Lyctinae, the powderpost beetles.

Species include:

Trogoxylon aequale

Trogoxylon angulicollis

Trogoxylon auriculatum
