Triozidae is one of seven families collectively referred to as jumping plant lice. They have traditionally been considered part of a single family, Psyllidae, but recent classifications divide the group into a total of seven families; most of the genera (over 70) remain in the Psyllidae, but Triozidae is the second-largest family in the group, containing 27 genera, and a number of pest species.
