Chrysauginae
Scaly-legged Pyralids
Chrysauginae is a subfamily of snout moths (Pyralidae) comprising approximately 400 described species. The subfamily is primarily Neotropical in distribution and includes notable specialized groups such as sloth moths, whose larvae feed on sloth dung and adults inhabit sloth fur. Most species have plant-feeding larvae that bore into seeds, fruits, stems, and roots or construct leaf shelters.
Epipaschiinae
snout moths
Epipaschiinae is a subfamily of Pyralidae (snout moths) containing over 720 described species. The group is predominantly tropical and subtropical in distribution, with notable absence from Europe as native fauna. Adult males exhibit distinctive morphological traits including an upturned third segment of the labial palpi, a ventrally curved phallobase extending beyond the ductus ejaculatorius, weakly sclerotized tegumen, and often a conspicuous scaled projection from the scape of the antennae. Larvae are leaf rollers, leaf tiers, and leaf miners; some species are minor crop pests on avocado, mahogany, and corn.
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.
Phycitinae
Knot-horn Moths
Phycitinae is a subfamily of snout moths (Pyralidae) representing the most diverse lineage within its family, encompassing over 600 genera and more than 4,000 species—more than three-quarters of living snout moth diversity. Together with Epipaschiinae, they form the most advanced lineage of snout moths. Adults are typically small, slender-bodied moths with well-developed proboscises and often elongated labial palps forming a 'snout.' The subfamily exhibits remarkable ecological diversity, with larvae occupying roles as leaf rollers, seed feeders, gall inquilines, aquatic predators, and agricultural pests.
Thyrididae
Window-winged Moths, Picture-winged Leaf Moths
Thyrididae is a family of moths commonly known as window-winged or picture-winged leaf moths, distinguished by square or rectangular translucent spots on their wings. The family comprises the sole member of superfamily Thyridoidea, with over 760 described species worldwide and hundreds more awaiting description. Most species inhabit tropical and subtropical regions, with only about 12 species recorded in North America. Adults of many species are diurnal and colorful, exhibiting day-flying behavior unusual among moths.
Thyris
window-winged moths
Thyris is a genus of window-winged moths in the family Thyrididae, characterized by distinctive square or rectangular translucent spots in their wings that give the group its common name. These small, often diurnal moths are primarily pantropical in distribution, with approximately 12 species known from North America among over 760 species worldwide. The genus includes species such as Thyris maculata, which ranges widely across North America from Ontario to Georgia, Texas, and west to Colorado, Idaho, and Montana. Adults typically fly between March and October, with peak activity in May through July.
