Dicercini is a tribe of metallic wood-boring beetles ( Buprestidae) comprising over 30 and more than 750 described . Members are characterized by their metallic coloration and association with woody plants. The tribe includes economically significant species such as Dicerca asperata, which has been documented as larvae inside dead branches of living trees. The tribe is classified within Chrysochroinae and is distributed across multiple biogeographic regions.

Identification

Dicercini can be distinguished from other Buprestidae tribes by features of the Chrysochroinae, including specific antennal and prosternal characteristics. Within Chrysochroinae, Dicercini is part of the dicercioid lineage sensu Bellamy (2003), characterized by particular morphological traits separating it from the chrysochroid lineage (tribe Chrysochroini) and other lineages. The tribe includes such as Dicerca, Hippomelas, Gyascutus, and Barrellus. -level identification requires examination of elytral , coloration patterns, and male genitalia.

Habitat

Associated with woody vegetation. Larvae develop in wood, with documented cases of in dead branches of living trees (1.0–3.5 cm diameter) where they construct pupal chambers near the branch surface. associations include flowers of plants such as Acacia angustissima and Chilopsis linearis.

Distribution

Widespread across multiple biogeographic regions including Nearctic, Palearctic, Neotropical, Afrotropical, Indomalayan, and Australian regions. Specific distribution varies by and .

Life Cycle

Larval development occurs within wood of plants. has been documented in the larval stage inside dead branches of living trees, with pupal chambers constructed near the branch surface. Complete with , larval, pupal, and stages.

Behavior

of some have been observed as strong, high fliers that hover over flowers before alighting. Adults groom themselves and rest on foliage after feeding.

Ecological Role

Wood-boring larvae contribute to decomposition of dead and dying woody material. may serve as when visiting flowers.

Human Relevance

Some are economically significant as pests of woody plants. Members of the tribe are frequently collected and studied by entomologists, with specimens representing important voucher material for distributional and biological research. The tribe includes species of interest to collectors due to their metallic coloration.
