(= Buprestidae: Acmaeoderinae, Polycestinae, Chalcophorinae, Sphenopterinae and Chrysobothrinae).
Classification. Polyphaga: Elateriformia.
Distribution. The subfamily Buprestinae occurs in all major regions of the world.
Biogeographic regions: Nearctic, Palearctic, Neotropical, Afrotropical, Oriental, Australian.
Biology. Adult Buprestinae feed primarily on the foliage of their host plants, but floricolous habits are known in the tribes Acmaeoderini, Anthaxiini and Stigmoderini. Buprestine larvae are wood borers, attacking living or dead trees or shrubs. Larvae may attack various parts of the host plant and hosts include gymnosperms, monocots and dicots. Some Buprestis species oviposit in conifers and may continue their development for long periods in seasoned wood, emerging from structural wood as much as 50 years later.
