Psyllidae is a family of small, jumping insects commonly referred to as "jumping plant lice" or "psyllids". These tiny insects feed on the sap of plants, often causing damage to leaves and stunting growth. Some synonyms for the word Psyllidae include: psyllid bugs, jumping plant bugs, and plant-lice. These synonyms emphasize the specific characteristics of these insects and their behavior, such as their tendency to jump from plant to plant. While psyllids may be a nuisance to gardeners and farmers, they also play an important role in the ecosystem, serving as a food source for other insects and predators.
