Definition
Psyllidae refers to a family of small, sap-sucking insects, commonly known as jumping plant lice. These critters are plant-specific, meaning each species typically feeds on only one or a few related plants. They jump readily when disturbed, like tiny fleas on foliage. Think of them as the annoying relatives of aphids, but with better hops. ðŋ They can sometimes transmit plant diseases. These insects are often host-specific, which means they usually only feed on one type of plant. Psyllidae are found worldwide, with many species in temperate regions.
