Phyllidae

Phyllidae is a family of leafhoppers, belonging to the order Hemiptera. These insects are characterized by their elongated, leaf-like bodies, which are adapted for their arboreal lifestyle. They are found worldwide, with the highest diversity in tropical regions. Phyllidae are herbivorous, feeding on a variety of plant species, including trees, shrubs, and herbs. Their diet primarily consists of phloem sap, which they extract using their specialized mouthparts.

The family Phyllidae is divided into several subfamilies, each with its own unique characteristics. The most well-known subfamily is Phyllinae, which includes the genus Phyllium, the type genus of the family. Phyllium species are often referred to as "leafhoppers" due to their leaf-like appearance and their ability to jump long distances. Other subfamilies include Phylliniidae, which are found in the New World, and Phylliniidae, which are found in the Old World.

Phyllidae are important in their ecosystems as they help disperse plant seeds and contribute to nutrient cycling. They are also of interest to entomologists due to their unique biology and behavior. Despite their ecological importance, many species of Phyllidae are threatened by habitat loss and other environmental factors. Conservation efforts are underway to protect these insects and their habitats.
