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.

Sepedon sphegea is a Palearctic species of fly in the family Sciomyzidae, the marsh flies or snail-killing flies. The larva feeds on aquatic snails and as an opportunist on other invertebrates. The habitat of this species includes among many others, pond margins and damp meadows. It has a particular fondness for Iris pseudacorus which grow at the edges of the pond. Adults can be found all year long but the main flight period is from March to October.

Intensely spotted wings.The interocular space with a black mark at the anterior orbital.The face is white with a black or brown central point. The antennae are reddish, the arista yellow at the base.The body is black covered in a grey yellow pruinosity with shifting (changeant) brown spots on the abdomen.The femora are grey with a brown apical band.The tibia are yellow with a brown apical ring (anneau). For terms see Morphology of Diptera. Dictya montana is a predator of aquatic pulmonate snails with no apparent parasitoid tendency.
Elgiva cucularia is a species of fly in the family Sciomyzidae. It is found in the Palearctic .Long. : 5-8 mm.Overall it is coloured yellowish-brown with a bluish-gray body. The head is characterized by silky black dots at the bases of the anterior orbital setae, between the bases of the antennae and the edges of the compound eyes, and in the centre of the occiput. The third antenna segment is a little shorter than the second. The mesonotum is black with a grey ground and grey pruinosity.There are longitudinal, brown stripes on the dorsum of the thorax: two narrow in the middle and two wide on the sides. One mesopleural bristle amongst short setae.The prothorax is bare. The yellowish smoky wings are 5.2 to 6.8 mm long and have fuzzy spots on the front half. The legs and abdomen are yellow. The lower surfaces of the hind femora are equipped with setae, while the front pair lacks them.The abdomen is rufous.For terms see Morphology of Diptera. Larvae of E. cucularia are predators of aquatic, pulmonate snails in the families Lymnaeidae, Physidae, and Planorbidae.
Hydromya dorsalis is a species of fly in the family Sciomyzidae. It is found in the Palearctic. It is the only species in the genus. Males have two elongated processes on the anterior margin of the fourth abdominal sternite. Larvae of Hydromya dorsalis are adapted for aquatic life and prey on aquatic pulmonate snails: Galba truncatula, Lymnaea sp. and Stagnicola palustris. Because of this, they are commonly referred to as snail-killing flies. Adults are found on vegetation all year round but the main flight period is April to October. H. dorsalis is known from most of the Palaearctic and some parts of the Afrotropics countries.
Ilione albiseta is a species of fly in the family Sciomyzidae. It is found in the Palearctic .The body length is 8 to 11.2mm and the basic colour is yellowish-brown. The spot on the occiput, the spots at the base of the frontal orbital setae and the almost triangular spots at the edge of the eyes at the height of the antennae are silky dark brown. The long antennae have a whitish hairy arists. There are longitudinal, brown stripes on the yellowish-dustedmesonotum : two narrow in the middle and two wide on the sides. In addition, there is a brown band on the body below the notopleura. The prosternum is bare. Chaetotaxy of the thorax shows strong presutural acrostichal setae and 2–3 well-developed subalar setae. The wings are 6.8 to 8 mm long and usually have 5 marks: on the anterior transverse vein, the medial vein, and the two ends of the posterior transverse vein. If there are only 2 dots on the medial vein, the transverse veins are at least darkened. The legs are yellow with darkened tarsi. The lower surfaces of the femora of the hind legs are equipped with strong and dense setae in males, and with short and sparse setae in females. Males are characterized by a copulatory apparatus with non-swollen abdominal pituitary glands.For terms see Morphology of Diptera. The larva preys on Galba truncatula
Pherbellia ventralis is a species of fly in the family Sciomyzidae. It is found in the Palearctic. Pherbellia ventralis is a small sciomyzid. The body is dark grey blue to blue grey contrasting with the yellowish brown abdomen.The mid-frontal stripe is short. The larvae feed on aquatic snails including Stagnicola palustris.
Pteromicra angustipennis is a species of fly in the family Sciomyzidae. It is found in the Palearctic. It is a small sciomyzid with 1 + 2 dorsocentral bristles.The transverse veins of the wings have no shadows but they are distinctly shaded at the apex. The larvae predators of terrestrial snails or stranded freshwater pulmonate snails.
