Summary

Laemophloeidae, commonly known as lined flat bark beetles, is a family of beetles characterized by flattened bodies and unique adaptations in male genitalia and larvae. They thrive in forested regions, notably under bark, and some species are important pests of stored grain.

Physical Characteristics

Adults typically range from 1–5 mm in length, mostly 1.5–3 mm; bodies are flattened, with sublateral lines on the head and pronotum, and elongated antennae. Male genitalia are inverted, and some genera exhibit modifications to male antennae, with expanded scape into hook-like or blade-like structures.

Identification Tips

Look for the flattened body shape and ridges or grooves on the head and pronotal discs. Male antennae may show unique modifications. Size is small, primarily under 5 mm.

Habitat

Most commonly found under the bark of dead trees; also present in stored grain products or galleries of bark beetles.

Distribution

Worldwide distribution, with greatest species richness in tropical regions. Present on all continents except Antarctica.

Diet

Primarily fungivores, though some species, particularly in the genus Cryptolestes, are known pests of stored grain products.

Life Cycle

Some larvae possess paired prosternal silk glands used to spin a cocoon for pupation, which is unique among insects.

Ecosystem Role

Primarily fungivores, contributing to the decomposition of wood and the cycling of nutrients. Some species affect grain storage industries.

Economic Impact

Several species, especially in the genus Cryptolestes, are important pests of stored grain products, resulting in economic losses.

Evolution

Historically regarded as a subfamily within Cucujidae, now recognized as a distinct family since the mid-20th century.

Misconceptions

Some species are incorrectly assumed to be harmless as they are small, but certain genera can be significant pests of stored grains.
