Buprestis

Members of Buprestis can be distinguished from other Buprestidae genera by their moderately large size combined with brilliant metallic coloration. Subgenera are morphologically distinct: Cypriacis species have elytra with alternate intervals depressed and heavily punctate, creating a strongly ribbed appearance; Stereosa species possess large punctures on the elytra; Knulliobuprestis species such as B. confluenta display confluent fine yellow flecks densely scattered over the elytra. Specific identification often requires examination of elytral sculpture, color patterns, and in some cases genitalia.

Habitat associations vary by species and subgenus. Members of subgenus Stereosa have been beaten from needles of young, healthy pines. Some species are associated with large, dead, bark-less cottonwood (Populus deltoides) and quaking aspen (P. tremuloides) trunks. Others occur on Virginia pine (Pinus virginiana) in exposed, sunny conditions. Alder (Alnus) has been documented as a host for related buprestid taxa found in similar habitats.

Distributed across most of the world's biogeographic realms including the Nearctic, Palearctic, Neotropical, Indomalayan, and Australian regions. Notably absent from parts of Africa and Antarctica. Within North America, species occur across the United States and Canada, with some showing restricted distributions in the western and central states and provinces.

Larvae are wood-borers, developing in structural wood or dead trees. Development can be prolonged; adults of B. aurulenta emerged from logs cut in 1946-47 beginning in 1956, indicating a developmental period of approximately 10 years. Some species overwinter as adults in pupal cells, while others overwinter as pupae and become adults in spring. Adults emerge early in the following season.

Adults are generally not very skittish and are relatively easy to capture compared to faster-flying relatives such as Chrysobothris. Adults are often found sitting on tree trunks and may be disinclined to flee when approached. Some species have been observed flying to or around host trees.

Larvae function as wood-borers in dead and dying trees. Adults may carry fungal associates; B. aurulenta has been documented with diverse fungal isolates including hyphomycetes, zygomycetes, yeasts, and basidiomycetes, though the beetle does not appear to consistently vector decay fungi into woody debris.

Highly valued by insect collectors due to brilliant metallic coloration, moderately large size, and relative rarity of some species. Some species are threatened by collection pressure, forest fires, and climate change. Prolonged larval development in structural wood can result in adult emergence in buildings decades after wood harvest. Misidentifications have occurred in the literature, including erroneous reports of exotic species establishment that were later corrected.

• ChrysobothrisBoth are jewel beetle genera with metallic coloration, but Chrysobothris species are generally smaller, more agile, and quicker to take flight than Buprestis species.
• AgrilusBoth are Buprestidae genera with wood-boring larvae, but Agrilus species are typically smaller with more elongated bodies and different elytral sculpture.

B. haemorrhoidalis was erroneously reported as established in British Columbia, Canada based on a misidentified specimen of the native North American species B. subornata. This erroneous record propagated through multiple publications and databases before being corrected through examination of the voucher specimen.
