The Info List - Bibionomorpha

--- Advertisement ---


The BIBIONOMORPHA are an infraorder of the suborder 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 representatives of the Bibionomorpha
are saprophages or fungivores as larvae with the Cecidomyiidae
being predominantly gall -formers. Some Sciarids are common indoor pests, developing large populations in potting soil that has become moldy from overwatering. The larvae of the Bibionidae
sometimes migrate in large, snake-like masses to minimize dehydration while seeking a new feeding site.
