Leafhoppers are small, jumping insects belonging to the family Cicadellidae. They are typically green or brown and can be found on various plants, where they feed on sap. Their ability to jump long distances helps them evade predators and move quickly between plants. These insects play a role in the ecosystem as both herbivores and potential pests. While they can help with pollination, some species are known to transmit plant diseases, affecting crops and gardens. Leafhoppers are an important part of the food web, serving as prey for birds and other insects.
