[5] Canacidae adults are mainly found on seashore habitats such as beaches, estuarine tidal flats, wave-swept rocks and mangroves.

[7] Carnidae are scavengers found in various kinds of plant matter, animal dung, carrion and vertebrate nests.

[5] Chloropidae are more varied in their larval ecology, including scavengers, herbivores in plant shoots and stems (these may be largely bacterial feeders), parasites feeding on frog blood, and predators of insect or spider eggs.

[2] Adults of Inbiomyiidae are believed to be microbial grazers, as dissections have found fungal, algal and probably bacterial material in their guts.

[3] Australimyzidae and Inbiomyiidae are sister groups, meaning they are more closely related to each other than to any other family.
