Subtribe Cetoniina

Cetoniina is a subtribe within the tribe Cetoniini (Subfamily Cetoniinae, Family Scarabaeidae, Order Coleoptera). It comprises a diverse group of flower chafers, many of which are noted for their bright metallic coloration and active daytime behavior.

Members of Cetoniina typically possess a robust, oval to elongate-oval body form, often smooth and glossy. Coloration is frequently vivid and metallic—commonly green, bronze, gold, or iridescent—with some species exhibiting contrasting spots, stripes, or patterned elytra. The pronotum and elytra are usually well-developed and streamlined, contributing to efficient flight.

Like other flower chafers, species in this subtribe are capable of flying without fully opening their elytra, as the hind wings extend through lateral openings beneath the wing covers. This adaptation allows rapid takeoff and maneuverability while visiting flowers.

Adults are primarily diurnal and are often observed on flowers, tree sap flows, or ripe fruits, feeding on nectar, pollen, sap, and soft plant tissues. In contrast, larvae are typically saprophagous, developing in decaying wood, compost, humus-rich soil, or organic debris, where they contribute to decomposition processes.

The life cycle follows complete metamorphosis: egg, larva (C-shaped grub), pupa, and adult. Larvae possess strong mandibles adapted for feeding on decomposing material rather than living roots.

Subtribe Cetoniina represents a core lineage of flower chafers, distinguished by metallic coloration, flower-associated adult ecology, and an important ecological role in pollination and nutrient recycling.
