**Larvae - Family diagnosis**

Elongate, usually narrow, slightly flattened or subcylindrical; lightly sclerotized except for head, usually tergite 9, often thoracic, occasionally abdominal tergites; usually reddish or pink; vestiture of fine setae, these sometimes long and dense. Head usually elongate or subquadrate; epicranial suture Y-shaped, epicranial stem long, frontal arms straight; median endocarina absent; ocelli present, 1 to 5 on each side. Mandibles usually apically bidentate; prostheca a single or divided process, lined posteriorly with fine setae. Ventral mouthparts retracted, maxillolabial complex (stipes and mentum) as long as gula; cardo much shorter than stipes; mala bearing pedunculate seta. Gula short; paragular areas usually membranous so that head is open behind; hypostomal rods absent. Protergum usually with single plate; pro-, meso-, and metatergum sometimes, abdominal tergites 1 to 8, rarely with paired sclerites. Thoracic tergites and abdominal tergites 1 and 8 or 1 to 8 usually with 1 or 2 pairs of glandular openings.
