The green leafhopper, scientifically known as Cicadella viridis, is a hemipteran insect belonging to the Cicadellidae family. Like other leafhoppers, it feeds on plant sap using its specialized mouthpart called a rostrum.

The body length ranges from 7 to 9 mm. Female green leafhoppers typically have green forewings, while males display a variety of colors, including blue, dark brownish, and purplish hues. The head's front edge is rounded and bicolored, with the pronotum being yellow at the front and green at the back.

Cicadella viridis was first described by Carl Linnaeus in 1758. The common name "green leafhopper" more accurately describes the females of the species.

This species is widespread across Europe and Asia, thriving in moist, marshy, or boggy environments. It inhabits herbaceous plants and shrubs, where it can cause damage by laying eggs in young shoots. Adult green leafhoppers are typically seen in Europe from July to October.
