Kelp, Marsh, Thick-headed Flies and Allies
Sciomyzoidea is a superfamily of acalyptrate flies (Diptera: Acalyptratae) comprising at least 11 families, including the well-known Sciomyzidae (snail-killing or marsh flies), Sepsidae (scavenger flies), and Coelopidae (seaweed flies). The superfamily exhibits diverse ecological specializations, with some families associated with marine or coastal habitats and others with freshwater or terrestrial environments. The family Sciomyzidae is particularly notable for its larval predation and parasitism on gastropods.
