Families
Anisopodidae - wood gnats Bibionidae - march flies and lovebugs Bolitophilidae Cecidomyiidae - gall gnats Diadocidiidae Ditomyiidae Hesperinidae Keroplatidae Lygistorrhinidae Mycetophilidae - fungus gnats Pachyneuridae Rangomaramidae Sciaridae - dark winged fungus gnats

The Bibionomorpha are an infraorder of the order Nematocera. One of its constituent families, the Anisopodidae, is the presumed sister taxon to the entire suborder Brachycera. Several of the remaining families in the infraorder (those shown without common names) are former subfamilies of the Mycetophilidae, which has been recently subdivided. The family Axymyiidae has recently been removed from the Bibionomorpha to its own infraorder Axymyiomorpha.

Most of the flies in the Bibionomorpha are saprophages or fungivores as larvae, aside from the Cecidomyiidae, which are gall-formers. Some sciarids are common indoor pests, developing large populations in potting soil that has become moldy from overwatering. The larave of Bibionidae sometimes migrate in large, snake-like masses to minimize dehydration while seeking a new feeding site.
