Metallic wood borers

Buprestidae. Flat-headed borers (larvae).

The larvae of this family, along with those of long-horned beetles, are common wood borers. They are distinguished from the former entirely cylindrical forms by their unique, flattened, disk-shaped thorax, which is decidedly wider than the narrow abdomen.

Adults are often highly metallic colored, coppery or bronzy, green, blue, or reddish. They are robust, hard shelled and extremely varied in size (BL 3-70 mm), with an elongate, streamlined body and strongly tapering elytra posteriorly. They feed on foliage and bark; some are twig girdlers or leaf miners, and many frequent blossoms to feed on pollen and petals. They are sun loving and are habitually active on hot days during the midday hours when they are often seen walking on freshly downed logs and tree limbs.

Approximately 3,200 species are known from the Neotropics, where they occur in all major habitats from wet forest to desert, alpine barrens to the seacoasi.
