Chrysochroinae

Chrysochroinae is a subfamily of beetles within the family Buprestidae, commonly known as metallic wood-boring beetles. This subfamily is characterized by its members' distinctive metallic iridescence, which is often green, blue, or bronze. The iridescence is a result of structural coloration, where the beetles' exoskeletons are composed of microscopic pits that reflect light in a specific way.

Chrysochroinae beetles are known for their unique life cycle. The larvae, or grubs, bore into the wood of living trees, feeding on the sap and causing minimal damage to the tree. This behavior is beneficial to the trees, as it helps to aerate the wood and prevent rot. The adults, on the other hand, are not known to feed on plants and are primarily attracted to flowers for nectar and pollen.

The subfamily is found worldwide, with the highest diversity in the tropics. It includes over 1,000 species, with the majority belonging to the genus Chrysochroa. The beetles are often found in forests, woodlands, and gardens, where they can be seen feeding on flowers or resting on tree trunks.

Chrysochroinae beetles are of interest to both scientists and collectors. Their unique iridescence and interesting life cycle make them a subject of study in the fields of entomology and ecology. Additionally, their beauty and rarity make them popular among collectors, who seek to add these beetles to their collections.
