Crambinae
Guides
Argyria
Argyria is a genus of moths in the family Crambidae, subfamily Crambinae. The genus was established by Jacob Hübner in 1818. Members of this genus are part of the diverse snout moth fauna, with nearly 6,000 observations recorded on iNaturalist. The genus name derives from Greek 'argyros' (silver), likely referencing the silvery or pale coloration typical of many crambid moths.
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.
Chrysoteuchia
sod webworms, cranberry girdlers
Chrysoteuchia is a genus of Crambidae moths containing approximately 36 species worldwide, with exceptional diversity in China (33 species). The genus exhibits a Palearctic, Sino-Japanese, and Oriental distribution pattern. Species are strongly associated with humid to semi-humid environments and show cold tolerance with humidity-dependent distribution patterns. The cranberry girdler (C. topiarius) is a notable pest of cool-season turfgrasses, cranberries, and fir in North America.
Crambini incertae sedis
Crambini-incertae-sedis is a provisional tribal designation within the subfamily Crambinae (Crambidae). It comprises genera and species that have been historically placed in the tribe Crambini but lack definitive phylogenetic placement due to insufficient morphological or molecular data. These taxa are morphologically heterogeneous, preventing confident assignment to established tribes such as Crambini sensu stricto or Argyriini. The group serves as a taxonomic holding category pending further systematic revision.
Crambus bidens
forked grass-veneer
Crambus bidens, commonly known as the forked grass-veneer, is a small moth in the family Crambidae. It was first described by Philipp Christoph Zeller in 1872. The species is distributed across northeastern and north-central North America, with records from Massachusetts, New York, Ontario, New Jersey, Quebec, Michigan, Vermont, and Alberta. Its primary habitat is bogs.
Crambus girardellus
Girard's grass-veneer, Girard's grass-veneer moth
Crambus girardellus, commonly known as Girard's grass-veneer moth, is a small crambid moth described by James Brackenridge Clemens in 1860. It is found across northeastern and north-central North America, from the Canadian prairies through the Great Lakes region to the northeastern United States. The species is associated with grassland habitats, where its larvae develop as root-feeders.
Crambus leuconotus
Crambus leuconotus is a species of crambid moth described by Philipp Christoph Zeller in 1881. It belongs to the grass-veneer moth genus Crambus, a group characterized by slender bodies and distinctive labial palps that project forward like a snout. The species is known only from Colombia, with minimal observational records available. Like other members of Crambinae, it likely inhabits grassland or meadow environments, though specific ecological details remain undocumented.
Crambus trichusalis
Crambus trichusalis is a grass moth in the family Crambidae, described by George Duryea Hulst in 1886. It is restricted to the northern Great Plains of North America, with confirmed records from the Canadian prairies and adjacent U.S. states. The species is strongly associated with native grassland habitats.
Crambus whitmerellus
Whitmer's Grass-veneer
Crambus whitmerellus is a grass-veneer moth in the family Crambidae, described by Alexander Barrett Klots in 1942. It is a North American species associated with grassland habitats. Two subspecies are recognized: the nominate form and C. w. browni from Alberta and northern Montana. The species is part of a large genus of grass-feeding moths commonly known as sod webworms or grass-veneers.
Eoreuma callista
Eoreuma callista is a species of moth in the family Crambidae, first described by Klots in 1970. It is known from the southwestern United States, specifically Arizona and New Mexico. Little is documented about its biology, ecology, or economic significance. The genus Eoreuma includes other species such as E. loftini (Mexican rice borer), a major agricultural pest, but E. callista itself has not been reported as a crop pest.
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.
Fernandocrambus ruptifascia
Fernandocrambus ruptifascia is a species of grass moth in the family Crambidae, first described by George Hampson in 1919. It is known only from Mexico. The species has not been documented on iNaturalist and appears to be poorly represented in collections. As with other members of the genus Fernandocrambus, it likely inhabits grassland or meadow habitats, though specific ecological details remain undocumented.
Fissicrambus minuellus
Fissicrambus minuellus is a species of grass moth in the family Crambidae, described by Francis Walker in 1863. It is distributed across the Caribbean and southeastern United States, with records from Honduras, Cuba, Puerto Rico, and Florida. As a member of the subfamily Crambinae, it likely exhibits the slender body form and grass-associated habits characteristic of this group.
Fissicrambus profanellus
