Helle is a genus of small-headed flies. It is endemic to New Zealand. [2] The genus is named after Helle, the daughter of Athamas, from Greek mythology. [1]
Xylomyidae is a family of flies known commonly as the wood soldier flies. They are xylophagous and are associated with dead or dying wood.
Hover flies of the genus Microdon are unusual among the Diptera. Like other members of the subfamily, they are myrmecophiles, meaning they inhabit the nests of ants.
Enrico Adelelmo Brunetti was a British musician and entomologist. He specialized in the Diptera and worked for many years in India.
Xylota is a Holarctic genus of hoverflies similar in structure to the related genera Chalcosyrphus and Brachypalpoides. As the larvae are saprophytic they're usually found in rotting wood. The adult flies are generally associated with woodland and woodland edges and can often be seen running over the upper sides of leaves. Unlike other syrphids the adults of many species rarely visit flowers preferring instead to gather pollen from leaf surfaces. There are over 100 described species of which 12 can be found in Europe. Seven species have been recorded in Britain. Identification of species has been difficult and identifiction by photographs is risky.
Criorhina is a genus of hoverflies. Medium to large sized species, black or greenish black, with or without light ground markings mimicking bumblebees .The head is much flattened and broader than the thorax. The antennae are situated upon a prominent conical frontal process, The face is moderately produced below the eyes, downward or forward, in profile. The eyes are bare. The abdomen is elliptical or very short oval. Larvae found in rot holes or decaying hardwoods
Chalcosyrphus is a genus of hoverflies in the subfamily Eristalinae. Many species exhibit some degree of mimicry of various sawflies and other hymenopterans and are often brightly coloured or metallic in hue. The adults are similar in structure and behavior to the related genus Xylota but differ in larval morphology. They can be found throughout Europe, Asia, and North America and seem to prefer damper, boggy habitats. The larvae are saproxylic feeders in rotten wood in these habitats.
Voriini is a tribe of flies in the family Tachinidae. More junior homonyms exist of Wagneria than any other animal genus name.
Diasemopsis is a genus of stalk-eyed flies in the family Diopsidae. They are known from sub-Saharan Africa.
Rhagioninae is a worldwide subfamily of predatory snipe flies.
Philopotinae is a subfamily of small-headed flies. Their larvae are endoparasites of araneomorph spiders in the subgroup Entelegynae.
Panopinae is a subfamily of small-headed flies (Acroceridae). Their larvae are endoparasites of spiders in the infraorder Mygalomorphae.
The family Nothybidae contains only the genus Nothybus, a group of colorful and elongated flies. The family has been recently revised.
Acrocera is a genus of small-headed flies in the family Acroceridae.
Ogcodes is a genus of small-headed flies in the family Acroceridae. About 90 species have been described for the genus.
Parathalassiinae is a subfamily of flies in the family Dolichopodidae. It is part of an extended concept of the family, Dolichopodidae sensu lato, and forms a monophyletic group with Dolichopodidae sensu stricto. It was once placed provisionally in the subfamily Microphorinae as the tribe Parathalassiini.
Pterodontia is a genus of small-headed flies. There are at least 20 described species in Pterodontia.
Philopota is a genus of small-headed flies in the family Acroceridae. It is the type genus of the subfamily Philopotinae.
Panops is a genus of small-headed flies. It is endemic to Australia and the Papua region of Indonesia. Males and females measure 8.0–12.5 mm and 9.5–14.5 mm, respectively.
Apsona is a genus of small-headed flies. It contains only one species, Apsona muscaria, which is endemic to New Zealand. It is very similar to the North American species Eulonchus smaragdinus.
Cyrtinae is a subfamily of the Acroceridae. Their larvae are endoparasites of araneomorph spiders in the subgroup Entelegynae.
