Eupithecia is the largest genus of moths of the family Geometridae,^[3] and the namesake and type genus of tribe Eupitheciini. Species in the genus are, like those of other genera in the tribe, commonly known as pugs.^[4] The genus is highly speciose, with over 1400 species, and members of the genus are present in most of the world with exception of Australasia.^[3] Roughly a quarter of described Eupithecia species occur in the Neotropical realm, where they have an especially high species diversity in the montane rain forests of the Andes.^[5] The genus includes a few agricultural pest species, such as the currant pug moth, Eupithecia assimilata, which is a pest on hops,^[6] and the cloaked pug moth, Eupithecia abietaria, which is a cone pest in spruce seed orchards.^[7]

Adult specimens of Eupithecia are typically small, often between 12 and 35 mm, with muted colours, and display a large amount of uniformity between species.^[3] As a result, identification of a specimen as part of genus Eupithecia is generally easy, but identifying the exact species is difficult and often reliant on examination of the dissected genitals.^[3] Most species share a characteristic resting pose in which the forewings are held flat at a right angle to the body—that is, the costal margins of both forewings form a more-or-less horizontal line—while the hindwings are largely covered by the forewings.^[8] They are generally nocturnal.^[3]

Of the species where the larval behaviour is known, most feed from the flowers and seeds of their food plants rather than the foliage.^[3] Many species have a very specific food plant. The larvae of all but one^[9] of the endemic species of Eupithecia from Hawaii are ambush predators of a wide variety of insects and spiders.^[10] These ambush predators have raptorial legs, with which they grab prey that comes into contact with their hind end.^[10]
