The family Sciomyzidae belongs to the typical flies (Brachycera) of the order Diptera. They are commonly called marsh flies, and in some cases snail-killing flies due to the food of their larvae.
Here, the Huttoninidae, Phaeomyiidae and Tetanoceridae are provisionally included in the Sciomyzidae. Particularly the latter seem to be an unequivocal part of this group and are ranked as tribe of subfamily by most modern authors, while the former two are very small lineages that may or may not stand outside the family and are provisionally ranked as subfamilies here. Whether the and the group around warrant recognition as additional subfamilies or are better included in the Sciomyzinae proper is likewise not yet entirely clear. Altogether, the main point of contention is the relationship between the "Huttoninidae", "Phaeomyiidae", Sciomyzidae sensu stricto, and the Helosciomyzidae which were also once included in the Sciomyzidae.
Description and ecology
Marsh flies are generally slender, yellowish or brownish, about 0.5-1 cm (0.25-0.5 in) long. They have fairly prominent eyes, prominent forward-pointing antennae, and bristles on the hind femora (upper hind leg). The wings are often mottled with various light brown markings according to species.
Marsh flies are common along the edges of ponds and rivers, and in marshy areas. The adults drink dew and nectar. The larvae prey on or become parasites of Gastropoda (slugs and snails). Very little is known about the complete life cycle of these flies.
