Order:
Wings and wing pads absent. Eye spots sometimes visible, but compound eyes absent. Segmented legs absent, but sometimes fleshy prolegs present. Sometimes with distinct head, often without head or with head drawn deeply into thorax. Body flattened, cylindrical, or maggot-like.
Family:
Mandibles move against each other along a horizontal or oblique plane. Head complete and fully exposed. Spiracles absent (apneustic). Thoracic segments individually distinguishable. Thorax and abdomen similar in diameter or abdomen wider. If prothorax without prolegs, body usually smooth, shiny, and cream-colored, usually without any surface features except few setae, especially posteriorly, and sometimes single retractile anal proleg bearing few hooks. If prothorax with pair of ventral prolegs, then prothoracic and anal prolegs usually paired (even if divison slight and only at apex) and distinct dorsal fleshy projections and/or setae along body. Mature larvae approximately 2–15 mm long.
Genus:
Larva long, slender, shiny, almost featureless. Head capsule sclerotized, more than 1.8–2.0 times as long as wide, and conspicuously constricted anteriorly. Sclerotized posterior collar of head with half-circle expansion. Dorsal tubercles and setae absent. Setae of last abdominal segment (anal division) about 1/3 length of segment. Anal proleg absent.
