Buprestinae

Buprestinae can be distinguished from other buprestid subfamilies by the combination of: prosternum typically not prolonged into a large conical process (unlike Stigmoderini in some classifications); antennal serrations beginning at antennomere 4 or 5; and tarsal claws with distinct basal dentition. Within the subfamily, tribal distinctions rely on antennal structure, prosternal shape, and elytral sculpturing patterns. Chrysobothrini possess distinctly serrate antennae with 11 segments; Anthaxiini have short, weakly serrate antennae; Buprestini exhibit strongly serrate to pectinate antennae in males; Melanophilini and Xenorhipidini show intermediate forms.

Terrestrial habitats worldwide, with highest diversity in temperate and subtropical regions for wood-boring species, and moist tropical regions for leaf-mining species. Adults frequent flowers, bark surfaces, and foliage of host plants. Larval habitats include living and dead wood, bark, and leaf tissue.

Worldwide distribution across all biogeographic regions. Highest species diversity in the Nearctic (37% of described species), Palearctic (22%), and Neotropical (19%) regions. Documented from North America, Europe, Asia, Africa, Australia, and Central and South America. Specific records include Bulgaria, China (Yunnan, Hebei, Sichuan provinces), Peru, and Papua New Guinea.

Adult activity varies by latitude and species. Temperate species typically active from late spring through summer (May–August in North America). Some species associated with spring wildflowers (e.g., flowering dogwood in April–May). Flight periods documented for specific species include September for some western North American taxa.

Adults are phytophagous, feeding on pollen, nectar, and floral tissues. Documented feeding on petals of winecup (Callirhoe involucrata), flowers of Eriogonum, and various composite flowers. Larvae are predominantly xylophagous, tunneling in bark and wood of living or dead trees; some species are leaf-miners in tropical regions.

Holometabolous development with egg, larval, pupal, and adult stages. Larvae are the primary feeding and growth stage. Wood-boring larvae typically have extended development periods (1–3+ years), tunneling in phloem, cambium, and xylem. Leaf-mining species in tropics may have shorter larval periods. Pupation occurs in wood or soil. Adults are relatively short-lived, focused on reproduction and dispersal.

Many adults are strong, direct fliers. Some species exhibit flower-constancy, repeatedly visiting the same plant species. Antennal grasping during mating has been observed in related taxa. Cryptic coloration provides camouflage on bark surfaces; some species exhibit wasp-mimicry. Adults of some genera (Acmaeodera, Anthaxia, Agrilaxia) routinely visit flowers, while others are rarely observed on flowers. Flight behavior in Acmaeodera involves holding fused elytra together during flight, resembling small bees.

Larvae contribute to wood decomposition and nutrient cycling in forest ecosystems. Some species are primary colonizers of stressed, dying, or burned trees. Several species are significant forestry pests (e.g., Agrilus planipennis, emerald ash borer; A. mali; Lamprodila festiva; Melanophila acuminata) or invasive species that cause substantial economic and ecological damage. Adults serve as pollinators for some plant species through flower visitation.

Significant economic impact through damage to timber, fruit trees, and ornamental plantings. Emerald ash borer (Agrilus planipennis) is a major invasive pest in North America. Species are popular among insect collectors due to brilliant metallic coloration. Some species used in jewelry manufacture historically. Research subjects for studies on host-finding behavior, chemical ecology, and phylogenetics.

• ChrysochroinaeAnother large subfamily of Buprestidae; distinguished by different antennal structure and larval habits, though some tribes formerly placed in Chrysochroinae (e.g., Chalcophorini) now included there based on molecular phylogenetics
• AgrilinaeSubfamily containing many similar wood-boring species; distinguished by more cylindrical body form, shorter antennae, and different larval gallery patterns
• PolycestinaeSmaller subfamily with some flower-visiting genera like Acmaeodera; distinguished by body shape and antennal structure
