Epimartyria bimaculella
Epimartyria bimaculella is a species of primitive moth in the family Micropterigidae, described in 2012 from specimens collected in the Pacific Northwest of North America. It is one of the smallest members of its genus, with forewings measuring 4.6–5.3 mm. The species is distinguished by two pale yellowish spots on dark fuscous forewings, a pattern referenced in its Latin name. It inhabits moist forest environments where leafy liverworts occur.
Eriocraniella mediabulla
A small primitive moth in the family Eriocraniidae, described in 1986 from the Atlantic and Gulf coastal plain of the southeastern United States. Adults are active in early spring and possess distinctive metallic luster on the wings. The larvae are leaf miners on oaks, creating serpentine mines that expand into blotches.
Eriocraniella platyptera
Eriocraniella platyptera is a small primitive moth in the family Eriocraniidae. Adults are active in May with a single annual generation. Larvae are leaf miners that feed on oak species, particularly Quercus ilicifolia. The species was described by Donald R. Davis in 1978 and is known from the northeastern and southern United States.
Gazoryctra pulcher
Gazoryctra pulcher is a moth species in the family Hepialidae, a group commonly known as ghost moths or swift moths. It is known from the southwestern United States, with records from Colorado, New Mexico, and Utah. The species was described by Augustus Radcliffe Grote in 1865. Like other hepialid moths, it likely exhibits primitive moth characteristics including reduced mouthparts in adults.
Gazoryctra sciophanes
Gazoryctra sciophanes is a hepialid moth described by Ferguson in 1979. It belongs to a genus of 10 North American species distributed from Alaska to the southern Appalachians and southern Rocky Mountains. The species has a wingspan of approximately 35–38 mm. Its range includes North Carolina and Tennessee, with the genus notably absent from much of the southern-central United States despite apparently suitable forested habitat.
Hepialoidea
Ghost Moths, Swift Moths
Hepialoidea is a superfamily of moths comprising over 650 species in approximately 70 genera, commonly known as ghost moths and swift moths. The group is characterized by primitive morphological features including a regressed haustellum (reduced proboscis), short antennae, and distinctive wing venation with a displaced Rs3 vein. Hepialoidea has a cosmopolitan distribution except for Madagascar and Antarctica, with greatest diversity in the Southern Hemisphere, particularly southern South America, southern Africa, and the Australian region. The superfamily includes several families, with Hepialidae being the most species-rich; fossil evidence suggests an origin in the mid-Jurassic with Hepialidae diverging by the mid-Cretaceous approximately 95 million years ago.
Lampronia sublustris
Lampronia sublustris is a small moth in the family Prodoxidae, first described by Annette Braun in 1925. It occurs in western North America from southern British Columbia to northern California, with eastern records extending to Alberta, Utah, and Colorado. The species belongs to a family of primitive moths that includes yucca moths, though its specific biology remains poorly documented. Records of this species are sparse, with limited observational data available.
Neocrania bifasciata
Neocrania bifasciata is a small moth species and the sole member of the genus Neocrania. It belongs to the family Eriocraniidae, a primitive group of Lepidoptera. The species is endemic to the Coast Ranges of southern California and was described by Davis in 1978. It is one of the few eriocraniid species found in western North America.
Paraclemensia
maple leafcutter moths
Paraclemensia is a genus of primitive moths in the family Incurvariidae. Larvae are leaf miners that later construct portable cases from cut leaf pieces, earning the common name 'leafcutter' for at least one species. The genus includes species associated with maple (Acer) and, in at least one documented case, with Rosaceae hosts. Most detailed biological information comes from studies of P. acerifoliella, the maple leafcutter.
