Grass-moths
Guides
Argyriini
Argyriini is a tribe of crambid snout moths within the subfamily Crambinae. Members are small to medium-sized moths with relatively inconspicuous coloration. The tribe is distinguished by specific morphological features of the male genitalia, particularly the structure of the phallus and juxta. Many species are associated with grassland and wetland habitats where their larval hosts grow.
Calamotropha
Calamotropha is a genus of grass moths in the family Crambidae, subfamily Crambinae. Species in this genus are distributed across Europe, Asia, and Africa, with particular diversity in the Oriental and Afrotropical regions. The genus has been subject to taxonomic revision, with numerous species described from China and other regions. Adults are generally small to medium-sized moths with characteristic crambine morphology. Larval stages are typically associated with grasses and related plants.
Crambinae
Grass-veneers and Allies, snout moth grass borers, sod webworms
Crambinae is a large subfamily of Crambidae moths comprising over 1,800 species worldwide. Members are commonly known as snout moths, grass-veneers, or sod webworms. The subfamily is characterized by specialized morphological features including tympanal organs and a phallus attached medially to the juxta. Larvae are primarily root feeders or stem borers on grasses, with several species recognized as significant agricultural pests of maize, sugarcane, rice, and turfgrasses.
Diptychophora
Diptychophora is a genus of crambid moths established by Zeller in 1866. The genus contains approximately 17 described species distributed across the Americas, with species described from North America, Central America, and South America. Several species have been described relatively recently (2021), indicating ongoing taxonomic work. The genus belongs to the grass moth family Crambidae, a diverse group of small to medium-sized moths often associated with grasses and sedges.
Euchromiusini
Euchromiusini is a tribe of grass moths within the family Crambidae. The tribe comprises small to medium-sized moths associated primarily with grassland and savanna habitats. Members are predominantly distributed across the Old World, with highest diversity in the Afrotropical and Palearctic regions. The genus Euchromius, which gives the tribe its name, contains the majority of described species.
Fernandocrambus
Fernandocrambus is a genus of moths in the family Crambidae, subfamily Crambinae, erected by Aurivillius in 1922. The genus contains approximately 50 described species, many of which were described by J. F. G. Clarke in 1965 and Bleszynski in 1967. Species are distributed primarily in southern South America, including Chile, Argentina, and the Falkland Islands. The genus name honors Chilean entomologist Carlos Stuardo Fernández.
Herpetogrammatini
Herpetogrammatini is a tribe of moths in the subfamily Spilomelinae, family Crambidae, containing seven genera and approximately 286 species. The tribe was erected in 2019 based on molecular phylogenetic studies that resolved relationships within the species-rich Spilomelinae. It includes economically significant genera such as Herpetogramma, which contains species with leaf-rolling larval habits. The tribe represents a recently defined taxonomic grouping that reorganized previously scattered classifications within the Crambidae.
Prionapteryx
Prionapteryx is a genus of moths in the family Crambidae, subfamily Crambinae. The genus was established by Stephens in 1834 and contains approximately 50 described species distributed across multiple continents. Species within this genus are generally small to medium-sized crambid moths. Many species were described by Hampson in the early 20th century based on specimens from Africa and Asia.
Thaumatopsis
Thaumatopsis is a genus of grass moths in the family Crambidae, subfamily Crambinae. The genus contains approximately 15 described species distributed primarily in North America, with some species ranging into Central America. Adults are generally small to medium-sized moths with relatively plain coloration. Larvae are associated with grasses and related plants, though specific host associations remain documented for only some species.
Urola
Urola is a genus of moths in the family Crambidae, first described by Francis Walker in 1863. The genus is currently treated as a synonym of Argyria, though it remains in active use in some databases and taxonomic sources. Members of this genus are small to medium-sized pyraloid moths, part of the diverse grass moth group within Crambidae.
Vaxi
Vaxi is a genus of snout moths in the family Crambidae, established by Bleszynski in 1962. The genus contains five described species distributed in North America. Species in this genus are small moths associated with grassland and agricultural habitats.
Xubida
Xubida is a genus of grass moths in the family Crambidae, subfamily Crambinae. The genus was established by Schaus in 1922 and contains approximately 20 described species distributed primarily in the Americas. Most species were described in the early 20th century based on specimens from the United States and Central America. The genus remains understudied, with limited ecological and biological information available for most species.
