Bostrichoidea

The Bostrichoidea is a superfamily of beetles within the order Coleoptera. This group includes families such as the Anobiidae (drugstore and deathwatch beetles), Bostrichidae (branch and twig borers), Dermestidae (skin beetles), and Ptinidae (spider beetles). Members of Bostrichoidea are often associated with timber and can be destructive.1

Specifically, the powderpost beetle (subfamily Lyctinae) bores through seasoned wood, reducing it to powder, but avoids treated wood. Branch and twig borers (family Bostrichidae) also live in dry wood or under bark, with some species, like the palm borer, being quite large. Other members, such as the apple twig borer, can damage living fruit-tree branches. The lead-cable borer is known for boring into the lead covering of telephone cables.23
