The subfamily Culicinae is the largest subfamily of Culicidae, a family of Nematocera dipterans. The trees are attacked by larvae of different insects, including dipterans. This genus mostly eats orthopterans, coleopterans (beetles), dipterans, and myriapods. Other foods include crayfish, sow bugs, grasshoppers, trichopterans, lepidopterans, and dipterans. This a list of the dipterans found from Sri Lanka. Insects such as dipterans are known parasitoids of mollusks. Harlequin flies are small dipterans which resemble mosquitoes. Swiftlets are insectivores; hymenopterans and dipterans being the most abundant prey. The invertebrate fauna includes spiders, beetles, dipterans, hemipterans, and hymenopterae. The invertebrate fauna include spiders, beetles, dipterans, hemipterans, and hymenopterae. Hennig's works in Stuttgart dealt almost exclusively with taxonomic revisions of Dipterans. In Dipterans, oviposition is instead commonly observed. Bats may feed on termites, scarab beetles, orthopterans, lepidopterans and dipterans. Food items include small aquatic crustaceans (cladocerans, copepods and ostracods), aquatic dipterans and tadpoles. As a taxonomist, he specialised in dipterans (ordinary flies and mosquitoes).
