Formerly taken as a part of the Psyllidae, and even today the two are often treated simultaneously. Contrary to the Psyllidae, Triozidae larvae have an anterior lobe on their wingpads, that extends as far as the level of the front margin of the head. The larvae bear along the margins of the wingpads and head a series of specialised glandular setae, each producing a long wax-thread.
