Bocydium globulare, a treehopper found in tropical forests of South America, is known for its extraordinary helmet adorned with globular structures. These protrusions, resembling tiny spheres, likely serve as a defense mechanism against predators. As sap-feeders, they play a role in the ecosystem by influencing plant health and providing food for predators.

Bocydium globulare, commonly known as the Umbelliferous Treehopper, is primarily found in the tropical and subtropical regions of South America. This species is most commonly observed in countries such as Brazil, particularly in the Amazon rainforest and surrounding areas.

The typical habitat of Bocydium globulare includes dense, humid rainforests with abundant vegetation. It thrives in environments with a warm, moist climate and a consistent temperature range, typically found in lowland tropical forest ecosystems.

Bocydium globulare occupies a niche as a sap-feeding insect, often residing on the stems and leaves of trees and shrubs. It is adapted to living in areas with rich plant diversity, relying on its host plants for sustenance. The species exhibits a unique adaptation with its globular protrusions on its pronotum, which may play a role in deterring predators or aiding in camouflage among the foliage.
