Triozidae

Triozidae is one of seven families, collectively referred to as plant lice, based on the type genus Trioza. They had traditionally been considered part of a single family, Psyllidae, but recent classifications divide the superfamily into a total of seven families; most of the genera remain in the Psyllidae, but Triozidae is the third-largest family in the group.
