Walker-1863
Guides
Episimus transferrana
Episimus transferrana is a species of tortricid moth in the family Tortricidae, described by Francis Walker in 1863. It belongs to the subfamily Olethreutinae, a group known for including many internal-feeding larvae. The species has been recorded from the Galápagos Islands and the Brazilian state of Amazonas (BR-AM). Records remain sparse, with limited biological data available.
Euchlaena deplanaria
Deep Yellow Euchlaena Moth
Euchlaena deplanaria is a species of geometrid moth native to eastern and central North America. Adults have a wingspan of approximately 34 mm and are active from February through October, indicating a broad flight season. The species is attracted to artificial light sources and has been documented in diverse habitats from deciduous forests to mixed conifer woodlands. It belongs to the genus Euchlaena, which includes several similarly patterned species that can be challenging to distinguish without close examination.
Eucosma bipunctella
Eucosma bipunctella is a small tortricid moth described by Francis Walker in 1863. As a member of the genus Eucosma, it belongs to a diverse group of moths commonly known as phaneta or eucosma moths. The specific epithet 'bipunctella' refers to two spots, likely describing a diagnostic wing pattern. Like other Olethreutinae, the larvae are likely internal feeders in plant tissues.
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.
Nemoria bifilata
White-barred Emerald, white-barred emerald moth
Nemoria bifilata, commonly known as the white-barred emerald moth, is a species of emerald moth in the family Geometridae. It was first described by Francis Walker in 1863 and is native to North America. The species is assigned MONA/Hodges number 7045. Two subspecies are recognized: N. b. bifilata and N. b. planuscula.
Nycteola frigidana
Frigid Owlet, Frigid Midget
Nycteola frigidana is a small nolid moth native to North America. It belongs to the subfamily Chloephorinae, a group known as the green oak moths or noline moths. The species was originally described as Tortrix frigidana by Francis Walker in 1863. It is recorded from Canada and the northern United States.
Pammene perstructana
Pammene perstructana is a small tortricid moth described by Walker in 1863, originally placed in the genus Sciaphila. It belongs to the tribe Grapholitini within the subfamily Olethreutinae. The species is documented from the Canadian provinces of Alberta and Manitoba. Like other members of the genus Pammene, it is likely associated with woody plants, though specific biological details remain poorly documented.
Tiquadra
Tiquadra is a genus of moths in the family Tineidae, established by Francis Walker in 1863. The genus comprises approximately 35 described species distributed across tropical and subtropical regions worldwide. Species have been recorded from the Americas, Africa, Asia, and Oceania, indicating broad biogeographic dispersal. As tineid moths, members likely exhibit the family characteristic of larval feeding on keratinous or plant materials, though specific biological details for most Tiquadra species remain undocumented.
Tortyra
Tortyra is a genus of moths in the family Choreutidae, established by Walker in 1863. The genus comprises approximately 23 described species distributed primarily in the Neotropical region, with some species extending into North America. These moths are generally small and exhibit metallic coloration, a common trait within their family.
Tulsa finitella
Tulsa finitella is a species of snout moth in the family Pyralidae, subfamily Phycitinae. First described by Francis Walker in 1863, this species is known from limited distribution records in the Canadian Prairie provinces. The genus Tulsa contains approximately 15 species, with T. finitella being among the more poorly documented members. Available occurrence data suggests it inhabits grassland and prairie environments, though specific ecological details remain sparse in the scientific literature.
Ufa
Ufa is a genus of snout moths in the family Pyralidae, subfamily Phycitinae, described by Francis Walker in 1863. The genus is distributed in the Americas and contains multiple species. Phylogenetic relationships suggest Ufa is most closely related to Elasmopalpus, though it shares certain morphological characters in female genitalia with Adelphia.
