Trogossitidae

Trogossitidae is a family of beetles, commonly known as bark-eating beetles or checkered beetles. These insects are typically medium-sized, with elongated and somewhat flattened bodies. Their coloration can vary, often featuring a combination of dark brown, black, and reddish-brown hues, sometimes with distinct patterns of spots or stripes. The antennae are usually serrated or filiform.

Larvae of Trogossitidae are fossorial, meaning they live underground or within decaying wood. They are often predatory, feeding on other insects and their larvae, particularly those found in bark crevices or under bark. Adult beetles also exhibit predatory behavior, hunting smaller insects and their larvae. Some species are also known to feed on fungi or decaying organic matter.

The family Trogossitidae is found worldwide, with the highest diversity in tropical and subtropical regions. They inhabit forests and woodlands where decaying wood and suitable prey are abundant. Some species are considered beneficial due to their role in controlling pest insect populations. However, a few species can occasionally infest stored products or timber, though this is less common. The classification of Trogossitidae has undergone revisions, with some genera previously placed in this family now assigned to other families.
