Psychodidae
Guides
Clogmia
drain flies, moth flies, filter flies, bathroom flies
Clogmia is a genus of small, non-biting drain flies in the family Psychodidae. Adults are 3–5 mm long with fuzzy, moth-like appearance due to dense hairs on wings and body. The genus includes the cosmopolitan species C. albipunctata, commonly known as the filter fly or bathroom fly, which frequently inhabits human dwellings. These flies are primarily nuisance pests associated with moist, decaying organic matter. Larvae play a documented role in sewage treatment as decomposers.
Clytocerus
Clytocerus is a genus of moth flies in the family Psychodidae, established by Eaton in 1904. The genus contains at least three described species: C. americanus, C. ocellaris, and C. tetracorniculatus. Records indicate presence in Europe and Southern Africa, with confirmed distribution records from Denmark, Norway, and Sweden.
Eurygarka
moth-flies
Eurygarka is a genus of moth-flies (Diptera: Psychodidae) containing three Nearctic species. The genus was established by Quate in 1959 and includes E. helicis (Dyar) and two recently described species from the southeastern United States: E. cyphostylus and E. nelderi. Adults of both sexes are known for all three species.
Feuerborniella opposita
Feuerborniella opposita is a species of moth fly in the family Psychodidae, first described by Nathan Banks in 1901. The genus Feuerborniella comprises small, delicate flies commonly associated with moist or aquatic environments. As a member of Psychodidae, it belongs to a diverse family of nematoceran Diptera with larvae typically found in wet habitats. The species is documented from a limited number of observations, suggesting it may be uncommon or underrecorded.
Maruina
Maruina is a genus of moth flies (Psychodidae) containing approximately 39 described species. The genus is unique among Psychodidae in being strictly aquatic, with larvae and pupae specially adapted for life in flowing water. It is restricted to the Western Hemisphere, with the majority of species occurring in the Neotropical region. The genus is divided into two subgenera: Aculcina and Maruina.
Nemopalpus
Nemopalpus is a genus of moth flies in the family Psychodidae, subfamily Bruchomyiinae. The genus was established by Macquart in 1838, with the original spelling 'Nemapalpus' corrected to 'Nemopalpus' in 1839. Recent taxonomic revisions in 2018 transferred several previously included species to the genera Alexanderia, Boreofairchildia, Laurenceomyia, and Notofairchildia. The genus currently contains ten recognized species distributed primarily in the Southern Hemisphere.
Paramormia
Paramormia is a genus of moth flies (Psychodidae) established by Enderlein in 1935. The genus contains at least 13 described species distributed across Europe, Asia, Africa, and North America. Species-level taxonomy has been revised multiple times, with several species described by Krek (1971, 1972), Vaillant (1972, 1973), and Ježek (2004).
Paramormia furcata
Paramormia furcata is a small moth fly (family Psychodidae) first described by Kincaid in 1899. The species has been reclassified under the genus Telmatoscopus in some taxonomic treatments, creating nomenclatural confusion. As a member of the Psychodidae, it belongs to a family of small, hairy flies commonly known as moth flies or drain flies, though specific ecological details for this species remain poorly documented.
Pericoma
moth flies
Pericoma is a genus of moth flies (family Psychodidae) comprising approximately 159–190 recognized species arranged in four subgenera. The genus has a nearly cosmopolitan distribution, with records from Europe, North America, and South America. Species within Pericoma are small, hairy flies characteristic of the Psychodidae family. The genus was established by Haliday in 1856 and remains taxonomically active with ongoing species descriptions.
Pericoma signata
moth fly
Pericoma signata is a species of moth fly in the family Psychodidae, described by Banks in 1901. It is found in eastern North America. The wing length measures approximately 2 mm. Like other moth flies, adults are characterized by their hairy bodies and wings, giving them a moth-like appearance. The species belongs to a family commonly associated with moist habitats and organic matter.
Platyplastinx
Platyplastinx is a genus of moth flies in the family Psychodidae, established by Enderlein in 1937. The genus is poorly documented in the scientific literature, with only 11 observations recorded on iNaturalist. Members of this genus belong to the diverse group of Psychodidae, commonly known as drain flies or moth flies due to their hairy wings and bodies. Specific ecological and biological details for Platyplastinx remain largely unstudied.
Platyplastinx sycophantos
Platyplastinx sycophantos is a species of moth fly in the family Psychodidae. It belongs to a genus characterized by distinctive wing venation and body flattening. Very few records exist for this species, with only one observation documented on iNaturalist. Its biology and ecology remain largely undocumented.
Psychoda sigma
moth fly
Psychoda sigma is a small moth fly in the family Psychodidae, commonly known simply as 'moth fly.' First described by Kincaid in 1899, this species belongs to the subgenus Tinearia within the genus Psychoda. Moth flies are characterized by their dense body pilosity and small size, typically measuring only a few millimeters in length. The species has been documented in North America and parts of Europe, including Belgium and Denmark.
Psychodinae
Moth Flies, Drain Flies, Filter Flies, Sewer Flies
Psychodinae is the nominate subfamily of moth flies (Psychodidae), commonly known as drain flies or filter flies. Adults are small, hairy flies rarely exceeding 5–6 mm in length, with distinctive kidney-shaped eyes connected by an eye-bridge. The subfamily has a cosmopolitan distribution, including subantarctic islands. Larvae are aquatic or semi-terrestrial, developing in diverse moist habitats ranging from natural springs and phytotelmata to artificial environments like drains and sewage systems.
Quatiella
Quatiella is a genus of moth flies (Psychodidae) established in 1970. The genus is placed within the diverse family of moth flies, characterized by their hairy bodies and broad, hairy wings. Members of this genus are small, delicate flies that inhabit moist environments. The genus has accumulated over 2,200 observations on iNaturalist, indicating moderate documentation in citizen science records.
Setomima
Setomima is a genus of moth flies (Psychodidae) described by Enderlein in 1937. It belongs to the tribe Brunettiini within the subfamily Psychodinae. The genus is characterized by specific wing venation patterns and setal arrangements that distinguish it from related psychodid genera. Species in this genus are small, delicate flies with hairy bodies and wings, typical of the family Psychodidae.
Thornburghiella
Thornburghiella is a genus of moth flies in the family Psychodidae, established by Vaillant in 1982. It belongs to the tribe Pericomini and is characterized by specific morphological traits that distinguish it from related genera. The genus contains relatively few described species and is poorly represented in biological collections.
Threticus bicolor
Threticus bicolor is a species of moth fly in the family Psychodidae, originally described as Psychoda bicolor by Nathan Banks in 1894. The species epithet 'bicolor' refers to its two-colored appearance. Like other members of Psychodidae, it belongs to a group of small, often hairy flies commonly known as moth flies or drain flies. The genus Threticus is part of the diverse psychodid fauna, though specific biological details for this species remain poorly documented in available literature.
