The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are the most controversial family in the superfamily Noctuoidea because many of the clades are constantly changing, along with the other families of the Noctuoidea. It was considered the largest family in Lepidoptera for a long time, but after regrouping Lymantriinae, Catocalinae and Calpinae within the family Erebidae, the latter holds this title now. Currently, Noctuidae is the second largest family in Noctuoidea, with about 1,089 genera and 11,772 species. However, this classification is still contingent, as more changes continue to appear between Noctuidae and Erebidae.
The geometer moths are moths belonging to the family Geometridae of the insect order Lepidoptera, the moths and butterflies. Their scientific name derives from the Ancient Greek geo γῆ or γαῖα "the earth", and metron μέτρον "measure" in reference to the way their larvae, or "inchworms", appear to "measure the earth" as they move along in a looping fashion. A very large family, it has around 23,000 species of moths described, and over 1400 species from six subfamilies indigenous to North America alone. A well-known member is the peppered moth, Biston betularia, which has been subject of numerous studies in population genetics. Several other geometer moths are notorious pests.
The Arctiinae are a large and diverse subfamily of moths, with around 11,000 species found all over the world, including 6,000 neotropical species. This group includes the groups commonly known as tiger moths, which usually have bright colours, footmen, which are usually much drabber, lichen moths, and wasp moths. Many species have "hairy" caterpillars that are popularly known as woolly bears or woolly worms. The scientific name of this subfamily refers to this hairiness. Some species within the Arctiinae have the word tussock in their common name due to people misidentifying them as members of the Lymantriinae based on the characteristics of the larvae.
The Pyralidae, commonly called pyralid moths, snout moths or grass moths, are a family of Lepidoptera in the ditrysian superfamily Pyraloidea. In many classifications, the grass moths (Crambidae) are included in the Pyralidae as a subfamily, making the combined group one of the largest families in the Lepidoptera. The latest review by Eugene G. Munroe and Maria Alma Solis, in Kristensen (1999) retains the Crambidae as a full family of Pyraloidea.
Saturniidae, commonly known as saturniids, is a family of Lepidoptera with an estimated 2,300 described species. The family contains some of the largest species of moths in the world. Notable members include the emperor moths, royal moths, and giant silk moths.
Oenosandridae is a family of Australian noctuoid moths. Genera include:
The pine processionary is a moth of the family Thaumetopoeidae. The species was first described by Michael Denis and Ignaz Schiffermüller in 1775. Sometimes placed in the genus Traumatocampa, it is one of the most destructive species to pines and cedars in Central Asia, North Africa and the countries of southern Europe. The urticating hairs of the caterpillar larvae cause harmful reactions in humans and other mammals. The species is notable for the behaviour of its caterpillars, which overwinter in tent-like nests high in pine trees, and which proceed through the woods in nose-to-tail columns, protected by their severely irritating hairs, as described by the French entomologist Jean-Henri Fabre.
Notodontidae is a family of moths with approximately 3,800 known species. The family was described by James Francis Stephens in 1829. Moths of this family are found in all parts of the world, but they are most concentrated in tropical areas, especially in the New World. The Thaumetopoeidae are sometimes included here as a subfamily.
The oak processionary is a moth whose caterpillars can be found in oak forests, where they feed on oak leaves, causing significant damage. They travel in nose-to-tail processions, often arrow-headed, with a leader followed by rows of several caterpillars abreast. They are a human irritant because of their venomous setae (hairs), which can cause skin irritation and asthma. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
The Lasiocampidae are a family of moths also known as eggars, snout moths, or lappet moths. Over 2,000 species occur worldwide, and probably not all have been named or studied.
The Coleophoridae are a family of small moths, belonging to the huge superfamily Gelechioidea. Collectively known as case-bearers, casebearing moths or case moths, this family is represented on all continents, but the majority are found in temperate areas of the Northern Hemisphere. They are most common in the Palearctic, and rare in sub-Saharan Africa, South America, and Australia; consequently, they probably originated in northern Eurasia. They are relatively common in houses, they seek out moist areas to rest and procreate.
Gracillariidae is an important family of insects in the order Lepidoptera and the principal family of leaf miners that includes several economic, horticultural or recently invasive pest species such as the horse-chestnut leaf miner, Cameraria ohridella.
The Cossidae, the cossid millers or carpenter millers, make up a family of mostly large miller moths. This family contains over 110 genera with almost 700 known species, and many more species await description. Carpenter millers are nocturnal Lepidoptera found worldwide, except the Southeast Asian subfamily Ratardinae, which is mostly active during the day.
Epicoma tristis, the dark epicoma, is a moth of the family Thaumetopoeidae first described by Edward Donovan in 1805. It is found in Australia.
Ochrogaster lunifer, the bag-shelter moth or processionary caterpillar, is a member of the family Thaumetopoeidae. The species was first described by Gottlieb August Wilhelm Herrich-Schäffer in 1855. Both the larval and adult forms have hairs that cause irritation of the skin (urticaria). The adult moth has a woolly appearance and its wings can grow to be about 5.5 cm across. The larvae feed on Grevillea striata at night and reside in brown silken bag nest during the day.
Aglaosoma variegata, the patterned notodontid, is a species of moth of the family Thaumetopoeidae first described by Francis Walker in 1855. It is known from the Australian states of New South Wales, Queensland and Victoria.
The Phycitinae are a subfamily of snout moths. Even though the Pyralidae subfamilies are all quite diverse, Phycitinae stand out even by standards of their family: with over 600 genera considered valid and more than 4000 species placed here at present, they unite up more than three-quarters of living snout moth diversity. Together with the closely related Epipaschiinae, they are apparently the most advanced lineage of snout moths.
Thaumetopoea is a genus of moths belonging to the family Notodontidae. It was first described by Jacob Hübner in 1820.
