Acrocera obsoleta
Acrocera obsoleta is a species of small-headed fly in the family Acroceridae, a group of Diptera characterized by their notably reduced head size and distinctive humpbacked appearance. The species was described by Wulp in 1867. Like other members of the family, it is likely parasitoid in its larval stage, though specific host records for this species remain undocumented. The genus Acrocera is one of the more speciose genera within this small, morphologically unusual family.
Ogcodes canadensis
Ogcodes canadensis is a species of small-headed flies in the family Acroceridae, described by Schlinger in 1960. Members of this family are characterized by their distinctive small heads and humpbacked appearance. The species is currently accepted as valid, though it has been listed as a synonym in some sources.
Ogcodes dispar
Ogcodes dispar is a species of small-headed fly in the family Acroceridae, first described by Macquart in 1855. The species is characterized by the distinctive morphology typical of the genus, including a small head and humpbacked thorax. It belongs to a family whose larvae are known to be internal parasitoids of spiders, though specific host associations for this species remain poorly documented. Available observations are limited, with only 12 records documented on iNaturalist.
Pterodontia
small-headed flies
Pterodontia is a genus of small-headed flies in the family Acroceridae, first described by Gray in 1832. The genus contains at least 20 described species. Members of this genus are characterized by distinctive morphological features including hairy eyes and reduced mouthparts. Like other acrocerids, they are likely parasitoids with specialized life histories, though detailed biological data remain limited for most species.
Pterodontia flavipes
small-headed fly
Pterodontia flavipes is a species of small-headed fly in the family Acroceridae. Adult males measure 5.5–10.5 mm, while females are 5–9 mm. The species exhibits complete metamorphosis with larval development occurring in soil. Adults have been observed in grassy areas and are known for rapid, hovering flight.
Pterodontia westwoodi
Pterodontia westwoodi is a species of small-headed fly in the family Acroceridae, described by Sabrosky in 1948. Members of this family are characterized by their distinctive humpbacked appearance and reduced head size. The genus Pterodontia is part of the subfamily Panopinae. Information regarding the specific biology and ecology of P. westwoodi remains limited, with only six observations recorded in iNaturalist.
Turbopsebius
Turbopsebius is a genus of small-headed flies (family Acroceridae) comprising approximately four described species. The genus was established by Schlinger in 1972 and belongs to the subfamily Cyrtinae. Species within this genus exhibit the characteristic reduced head morphology typical of Acroceridae, with adults bearing a small, globular head on a narrow neck.
