<span class="mw-page-title-main">Noctuidae</span> Type of moths commonly known as owlet moths, cutworms or armyworms

The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are a family of moths. They are considered 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. This classification is still contingent, as more changes continue to appear between Noctuidae and Erebidae.

<span class="mw-page-title-main">Noctuoidea</span> Superfamily of moths

Noctuoidea is the superfamily of noctuid or "owlet" moths, and has more than 70,000 described species, the largest number of any Lepidopteran superfamily. Its classification has not yet reached a satisfactory or stable state. Since the end of the 20th century, increasing availability of molecular phylogenetic data for this hugely successful radiation has led to several competing proposals for a taxonomic arrangement that correctly represents the relationships between the major lineages.

<span class="mw-page-title-main">Erebidae</span> Family of moths

The Erebidae are a family of moths in the superfamily Noctuoidea. The family is among the largest families of moths by species count and contains a wide variety of well-known macromoth groups. The family includes the underwings (Catocala); litter moths (Herminiinae); tiger, lichen, and wasp moths (Arctiinae); tussock moths (Lymantriinae), including the arctic woolly bear moth ; fruit-piercing moths ; micronoctuoid moths (Micronoctuini); snout moths (Hypeninae); and zales, though many of these common names can also refer to moths outside the Erebidae. Some of the erebid moths are called owlets.

<span class="mw-page-title-main">Erebinae</span> Subfamily of moths

The Erebinae are a subfamily of moths in the family Erebidae erected by William Elford Leach in 1815. Erebine moths are found on all continents except Antarctica, but reach their greatest diversity in the tropics. While the exact number of species belonging to the Erebinae is not known, the subfamily is estimated to include around 10,000 species. Some well-known Erebinae include underwing moths (Catocala) and witch moths (Thermesiini). Many of the species in the subfamily have medium to large wingspans, up to nearly 30 cm in the white witch moth, which has the widest wingspan of all Lepidoptera. Erebine caterpillars feed on a broad range of plants; many species feed on grasses and legumes, and a few are pests of castor bean, sugarcane, rice, as well as pistachios and blackberries.
