Argyresthia canadensis
Canadian arborvitae leafminer, cedar leafminer
Argyresthia canadensis is a small moth in the family Argyresthiidae, commonly known as the Canadian arborvitae leafminer or cedar leafminer. The species is found in North America and has a single generation per year. Larvae are specialized leafminers of Thuja occidentalis (northern white-cedar), feeding between the layers of needle tissue.
Atemelia
Atemelia is a genus of small moths within the family Praydidae (superfamily Yponomeutoidea). The genus was established by Herrich-Schäffer in 1853 and contains six described species distributed primarily in the Palearctic region, with records from northern Europe including Norway and Sweden. Species-level taxonomy has been subject to revision, with Atemelia formerly placed in Plutellidae by some sources.
Atteva
ermine moths, ailanthus webworms
Atteva is the sole genus in the family Attevidae, a group of small to medium-sized moths within the superfamily Yponomeutoidea. The genus has a pantropical distribution with approximately 70 described species. Most species occur in tropical regions of the Americas, Asia, and Oceania, though Atteva aurea has expanded into temperate North America following the introduction of its host plant, Ailanthus altissima (Tree of Heaven). Adults are often strikingly patterned in orange, black, and white, and several species are diurnal nectar feeders rather than nocturnal.
Cemiostominae
Cemiostominae is a subfamily of small moths within the family Lyonetiidae, first described by Spuler in 1898. The group belongs to the superfamily Yponomeutoidea, a lineage of microlepidoptera that includes many leaf-mining species. The subfamily contains genera such as Cemiostoma and Phrixe, though precise boundaries and included taxa have undergone revision. Members are characterized by reduced wing venation and distinctive larval habits.
Lyonetiidae
Lyonetiidae is a family of small moths comprising approximately 200 described species. Adults are characterized by their diminutive size, with wingspans rarely exceeding 1 cm, and distinctive narrow forewings with pointed, often up- or down-turned apices. The family is notable for its larval biology: all known larvae are leaf miners, feeding internally within leaf tissue. The family has been subject to taxonomic revision, with Bucculatricidae and Bedelliidae sometimes treated as subfamilies rather than distinct families.
