Hyposmocoma is a genus of moths with more 350 species endemic to the Hawaiian Islands. The genus was first described by Arthur Gardiner Butler in 1881. Most species of Hyposmocoma have plant-based diets, but four species, such as Hyposmocoma molluscivora, eat snails. The caterpillars spin silk, which they then use to capture and eat snails. These are the first caterpillars known to eat snails (or mollusks of any kind).
Some species are amphibious. This trait has evolved at least three times within this genus.
There are a number of undescribed species.
Attevidae is a family of moths of the Yponomeutoidea superfamily, containing only one genus, Atteva. The group has a pantropical distribution, but at least one species has a range that extends into the temperate zone. No consistent hypotheses regarding the relationships, placement, and ranking of Attevidae have been published, but the prevalent view is that they likely form a monophyletic group within the Yponomeutoidea.
Hyposmocoma molluscivora is a Hawaiian moth whose larvae are predators, capturing snails in their silk, much like a hunting spider's web, and then crawling inside the snail's shell to eat it alive. It has been called the snail-eating caterpillar or the flesh-eating caterpillar, though no common name has been widely prescribed to it.
Chionodes is a genus of moths of the family Gelechiidae. It is distributed throughout much of the world. The larvae of many species use the Douglas fir as a host plant.
Cydia is a large genus of tortrix moths, belonging to the tribe Grapholitini of subfamily Olethreutinae. Its distinctness from and delimitation versus the tribe's type genus Grapholita requires further study.
The Plutellidae are a family of moths commonly known as the diamondback moths, named after the diamondback moth of European origin. Some authors consider this family to be a subfamily of the Yponomeutidae, but it is usually considered to be a family in its own right, and have three subfamilies, Plutellinae, Praydinae, and Scythropiinae.
Aristotelia is a genus of moths in the family Gelechiidae. Well-known species are food plant specialists, and diverse hosts are used - Salicaceae, Solanaceae, Rosaceae, Fagaceae, Fabaceae, Asteraceae.
Gelechia is a genus of moths in the family Gelechiidae. The type species is Gelechia rhombella.
Merimnetria is a genus of moths in the family Gelechiidae. It was first described by Lord Walsingham in 1907. All species are endemic to Hawaii.
Ethmia is a large genus of small moths. It is the type genus of the gelechioid family Ethmiidae, which is sometimes included in Elachistidae or Oecophoridae as subfamily.
Archips is a genus of tortrix moths the tribe Archipini. Species include the oak leaf roller, and other notorious pests.
Ancylis is a genus of moths belonging to the subfamily Olethreutinae of the family Tortricidae.
Philodoria is a genus of moths in the family Gracillariidae. All species are endemic to Hawaii. It was first described by Lord Walsingham in 1907.
Caloptilia is a genus of moths in the family Gracillariidae.
Ypsolopha is a genus of moths of the family Ypsolophidae. It is the type genus of the family and comprises over 120 described species.
Agonopterix is a moth genus of the superfamily Gelechioidea. It is placed in the family Depressariidae, which was often – particularly in older treatments – considered a subfamily of the Oecophoridae or included in the Elachistidae.
Cerconota is a genus of moths in the family Depressariidae. In 1991, I. W. B. Nye and David Stephen Fletcher included it in the family Oecophoridae and the subfamily Stenomatinae. It was later placed in the family Elachistidae and subfamily Stenomatinae by Ronald W. Hodges, in Niels Peder Kristensen (1999). Other classifications placed them in the Elachistidae or Oecophoridae, but they actually seem to belong to the Depressariidae.
Gracillariinae are a subfamily of moths which was described by Henry Tibbats Stainton in 1854.
Gelechiinae is a subfamily of moths in the family Gelechiidae. It was described by Henry Tibbats Stainton in 1854.
