Gymnetini

Gymnetini is a tribe of beetles belonging to the subfamily Cetoniinae, within the family Scarabaeidae. These beetles are commonly referred to as flower chafers or flower beetles due to the adults often feeding on pollen and nectar in flowers.

Characteristics:

Gymnetini beetles typically exhibit the following characteristics:

• Size and Shape: They are generally medium-sized beetles, often oblong or oval in shape.
• Coloration: Their coloration can vary widely, ranging from metallic greens, blues, and coppers to browns, blacks, and combinations thereof. Some species exhibit spots or patterns.
• Elytra: The elytra (hardened wing covers) are usually smooth and may or may not completely cover the abdomen. A distinctive feature of many Cetoniinae, including Gymnetini, is the presence of a lateral emargination (notch) on the elytra, allowing them to fly with the elytra closed.
• Habitat: These beetles are found in a variety of habitats, including forests, meadows, and gardens, wherever flowering plants are abundant.
• Diet: As adults, Gymnetini are primarily phytophagous, feeding on pollen, nectar, and occasionally on the juices of fruits. The larvae typically feed on decaying organic matter, such as rotting wood or leaf litter.

Distribution:

Gymnetini are found in various regions around the world, with a particularly diverse representation in the Americas.

Taxonomy:

The classification of Gymnetini, like that of many beetle groups, is subject to revision as new research emerges. The taxonomy presented here reflects current understanding but may be updated in the future. The tribe contains multiple genera, varying depending on taxonomic classification.

Ecological Role:

Gymnetini play a role in pollination as they move from flower to flower while feeding. The larvae contribute to decomposition and nutrient cycling within their respective ecosystems.
