Bibionomorpha
Encyclopedia
Bibionomorpha is an infraorder of 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 name
s) 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 fungivore

are common indoor pests, developing large populations in potting soil that has become moldy from overwatering. The larave of Bibionidae
sometimes migrate in large snakelike masses in order to minimize dehydration while seeking a new feeding site.

Fungivore
A fungivore or mycophage is any animal that primarily or solely feeds upon living members of the fungus kingdom. Fungivory is a type of predation, and is an important part of the soil food web...

Larva
A larva is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle...

Cecidomyiidae
Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls.These are very fragile small insects usually only 2–3 mm in length and many are less than...

Gall
Galls or cecidia are outgrowths on the surface of lifeforms caused by invasion by other lifeforms, such as parasites or bacterial infection. Plant galls are abnormal outgrowths of plant tissues and can be caused by various parasites, from fungi and bacteria, to insects and mites...

Sciaridae
Sciaridae is a family of flies, commonly known as dark-winged fungus gnats. Commonly found in moist environments, they are known to be a pest of mushroom farms and are commonly found in household plant pots. This is one of the least studied of the large Diptera families, probably due to the small...
