Anarete
Anarete is a genus of non-biting midges in the family Cecidomyiidae, established by Irish entomologist Alexander Henry Haliday in 1833. The genus contains 38 described species with a cosmopolitan distribution. Several species, particularly Anarete pritchardi, have been extensively studied for their swarming behavior. Swarming in this genus involves males forming aerial aggregations with measurable kinematic properties, including characteristic looping and zigzag flight patterns while maintaining relatively constant distance from the swarm center.
Bruggmanniella
Bruggmanniella is a genus of gall midges (Cecidomyiidae: Asphondyliini) comprising approximately ten species that induce galls on various host plants. The genus is characterized by distinctive morphological features including three-segmented palpi, simple tarsal claws, and male gonostyli with teeth completely divided mesally. Species induce galls on stems, twigs, flower buds, ovaries, and fruits of diverse plant families including Lauraceae, Malpighiaceae, Annonaceae, Fabaceae, Celastraceae, Dilleniaceae, and Sapotaceae. Phylogenetic analysis confirms Bruggmanniella as a monophyletic Neotropical lineage, with Asian species reassigned to the genus Odontokeros.
Bruggmanniella bumeliae
Bumelia gall midge
Bruggmanniella bumeliae is a gall midge species in the family Cecidomyiidae, commonly known as the Bumelia gall midge. The species induces galls on plants in the genus Sideroxylon (formerly Bumelia), which includes species commonly called gum bully or false buckthorn. It was first described by Felt in 1907. The species has been documented across multiple observations, with iNaturalist recording approximately 470 observations, suggesting it is relatively well-documented among gall midges.
Caryomyia albipilosa
Hickory White-haired Gall Midge
Caryomyia albipilosa is a gall midge species described by Gagné in 2008. It belongs to the genus Caryomyia, a group of cecidomyiids associated with hickory trees (Carya spp.). The species is known from limited observations, with 75 records on iNaturalist as of the source data. Like other members of its genus, it likely induces gall formation on hickory foliage or stems, though specific gall morphology has not been widely documented.
Caryomyia spinulosa
Caryomyia spinulosa is a species of gall midge in the family Cecidomyiidae, described by Gagné in 2008. The genus Caryomyia comprises insects that induce galls on hickory and pecan trees (Carya species). As with other members of this genus, C. spinulosa likely forms characteristic galls on its host plants, though specific details of its biology remain poorly documented in published literature.
Caryomyia striolata
Caryomyia striolata is a species of gall midge in the family Cecidomyiidae, described by Gagné in 2008. It belongs to a genus specialized in inducing galls on hickory and pecan trees (Carya species). As a recently described species, detailed biological information remains limited.
Ceroptres
Ceroptres is a genus of gall wasps in the tribe Ceroptresini (Cynipidae). The genus includes 43 described species, of which 40 are known from North America. Ceroptres species are inquilines: they do not induce their own galls but instead oviposit into galls formed by other organisms. Host galls are primarily those induced by other gall wasps (Cynipini), though some species use galls formed by gall midges (Cecidomyiidae). Species are host specialists, typically associated with a single host gall species or with several phylogenetically or ecologically related galls.
Neolasioptera monardi
Neolasioptera monardi is a species of gall midge in the family Cecidomyiidae, described by Brodie in 1894. Gall midges in this genus are known for inducing galls on host plants. The species is rarely documented, with limited observational records available.
Parallelodiplosis
Parallelodiplosis is a genus of gall midges in the family Cecidomyiidae, described by Rübsaamen in 1910. The genus contains at least 20 described species. Like other cecidomyiids, these are small, delicate flies whose larvae induce gall formation on host plants. The genus is distributed across northern Europe and North America.
Pilodiplosis
Pilodiplosis is a genus of gall midges in the family Cecidomyiidae, established by Gagné in 1973. The genus contains at least one described species, P. helianthibulla. As gall midges, members of this genus likely induce gall formation on host plants, though specific biological details remain poorly documented.
Rhopalomyia
Rhopalomyia is a large genus of gall midges (Cecidomyiidae) comprising at least 220–267 described species with cosmopolitan distribution. Established by Ewald Heinrich Rübsaamen in 1892, most species induce highly specific galls on Asteraceae, though some species have expanded to Fabaceae, Apocynaceae, Ericaceae, and Myrtaceae. Galls occur on diverse plant organs including buds, leaves, stems, rhizomes, and flower heads. The genus exhibits complex host associations and gall polymorphism, with some species serving as biological control agents.
Schizomyia
Schizomyia is a genus of gall midges (Diptera: Cecidomyiidae) with cosmopolitan distribution. Species in this genus induce various types of galls on diverse host plants, including rosette bud galls, inflorescence galls, and stem galls. The genus belongs to the tribe Asphondyliini and contains at least 51 described species. Some species have significant ecological and economic impacts, including outbreaks that reduce seed production in forest trees and potential use as biological control agents.
