Eudocima phalonia, commonly known as the fruit-piercing moth, is a nocturnal insect found in tropical and subtropical regions. It has vibrant orange and green wings with distinctive eye spots. Known for its unique feeding behavior, it pierces fruits to consume the juices, impacting agriculture.

Eudocima phalonia, commonly known as the fruit-piercing moth, is native to a wide range of tropical and subtropical regions across the Old World. Its geographical distribution includes parts of Africa, the Indian subcontinent, Southeast Asia, Australia, and various islands in the Pacific Ocean. The species is notably present in countries such as India, Sri Lanka, Thailand, Malaysia, Indonesia, and Papua New Guinea.

Eudocima phalonia typically inhabits tropical and subtropical environments. These regions are characterized by warm temperatures and high humidity, often associated with dense vegetation. The moth thrives in areas with abundant fruit-bearing trees, as its larvae primarily feed on such plants. The presence of hosts like citrus and other fruit trees influences its habitat selection.

Eudocima phalonia occupies the ecological niche of a frugivore at the larval stage. It plays a role in the ecosystem by feeding on the juices of ripe fruits, which can impact local agricultural practices. The species has adapted to its environment by developing a strong proboscis to pierce fruit skins, allowing it to access the nutrients within. This adaptation is crucial for its survival and proliferation in its native regions.
