31-530: See text Ceratocampinae is a subfamily of moths in the family Saturniidae . Species can be found in the New World . This subfamily contains the following genera: This article on a moth of the family Saturniidae is a stub . You can help Misplaced Pages by expanding it . Moth Moths are a group of insects that includes all members of the order Lepidoptera that are not butterflies . They were previously classified as suborder Heterocera, but
62-551: A monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera , Heterocera and Rhopalocera , Jugatae and Frenatae, Monotrysia , and Ditrysia . Although the rules for distinguishing moths from butterflies are not well established, one very good guiding principle
93-641: A source of silk to replace the shortage of cotton caused by the American Civil War. Afterwards, several species of parasitoids and predators have been introduced as biological control agents in attempts to help control this moth. Beginning in the late 1800s, at least ten species were established this way, but for nearly a century, there was little regulation or research on the effectiveness or non-target effects of these introduced natural enemies. Several were generalists that offered little control of L. dispar and attacked other native insects. One such species
124-438: A variety of deciduous and coniferous trees and can cause severe damage in years of mass reproduction. Due to these features, Lymantria dispar is listed among the world's 100 worst invasive alien species . The etymology of “gypsy moth” is not conclusively known; however, the term is known to have been in use (as 'Gipsey') as early as 1832. Moths of the subfamily Lymantriinae are commonly called tussock moths due to
155-582: A virus ( LdmNPV ), and a fungus ( Entomophaga maimaiga ). In June 2024, the severity of the outbreak in the Northeast and Midwest of the United States was reported by Scientific American . These regions were experiencing one of the most severe outbreaks ever recorded, with some areas reporting densities exceeding 2,500,000 caterpillars per hectare (1,000,000 per acre), and certain regions have been grappling with this issue for five consecutive years. Since
186-769: Is a significant food resource in southern Africa . Another saturniid used as food is the cavorting emperor ( Usta terpsichore ). In one country alone, Congo , more than 30 species of moth larvae are harvested. Some are sold not only in the local village markets, but are shipped by the ton from one country to another. Nocturnal insectivores often feed on moths; these include some bats , some species of owls and other species of birds . Moths also are eaten by some species of lizards , amphibians , cats , dogs , rodents , and some bears . Moth larvae are vulnerable to being parasitized by Ichneumonidae . Baculoviruses are parasite double-stranded DNA insect viruses that are used mostly as biological control agents. They are members of
217-536: Is considered more effective, but there are concerns over its effects on human health. Despite being commonly thought to be undertaken by all moths, only the larvae of several moth species eat animal fibres, creating holes in articles of clothing, in particular those made of wool. Most species do not eat fabrics, and some moth adults do not even eat at all. Some, like the Luna , Polyphemus , Atlas , Promethea , cecropia , and other large moths do not have mouth parts. This
248-400: Is currently unknown. One hypothesis is called celestial or transverse orientation. By maintaining a constant angular relationship to a bright celestial light, such as the moon, they can fly in a straight line. Celestial objects are so far away that, even after travelling great distances, the change in angle between the moth and the light source is negligible; further, the moon will always be in
279-691: Is native to temperate Asia east of the Ural mountains. Since the early 1990s it has also been detected along the West Coast of temperate North America. From Southern Europe it is spreading northwards into Germany and other countries, where it hybridizes with the European spongy moth, L. d. dispar . A colony had been reported from Great Britain in 1995. Lymantria dispar was accidentally introduced into North America by artist and astronomer Étienne Léopold Trouvelot in 1869, who imported it from Europe while looking for
310-470: Is possible because they live off the food stores from when they were a caterpillar, and only live a short time as an adult (roughly a week for some species). Many species of adult moths do however eat: for instance, many will drink nectar . Items of fabric infested by clothes moth larvae may be treated by freezing them for several days at a temperature below −8 °C (18 °F). Some moths are farmed for their economic value. The most notable of these
341-491: Is that butterflies have thin antennae and (with the exception of the family Hedylidae ) have small balls or clubs at the end of their antennae. Moth antennae are usually feathery with no ball on the end. The divisions are named by this principle: "club-antennae" (Rhopalocera) or "varied-antennae" (Heterocera). Lepidoptera first evolved during the Carboniferous period, but only evolved their characteristic proboscis alongside

#1733086179113372-413: Is the silkworm , the larva of the domesticated moth Bombyx mori . It is farmed for the silk with which it builds its cocoon . As of 2002 , the silk industry produces more than 130 million kilograms of raw silk, worth about 250 million U.S. dollars , each year. Not all silk is produced by Bombyx mori . There are several species of Saturniidae that also are farmed for their silk, such as
403-498: Is the tachinid fly Compsilura concinnata , which attacked many other host species (over 180 known hosts documented), decimating many of the large moth species previously abundant in the Northeast. Another is the encyrtid wasp Ooencyrtus kuvanae which attacks L. dispar eggs but is not strictly host specific, and also parasitizes the eggs of other Lepidoptera species. The most effective control agents are microbial pathogens:
434-585: The Baculoviridae , a family that is restricted to insects. Most baculovirus isolates have been obtained from insects, in particular from Lepidoptera. There is evidence that ultrasound in the range emitted by bats causes flying moths to make evasive maneuvers. Ultrasonic frequencies trigger a reflex action in the noctuid moth that causes it to drop a few centimeters or inches in its flight to evade attack, and tiger moths can emit clicks to foil bats' echolocation. The fungus Ophiocordyceps sinensis infects
465-644: The Romani people ", since gypsy is considered an ethnic slur by some Romany people in North America. In January 2022, the new common name "spongy moth" was proposed, as a translation from the French name "spongieuse" for the species, referring to the sponge-like egg masses laid by L. dispar . Since the name Gypsy is widely embraced by Roma people as a self-referenced demonym in Europe, there has been no similar call to change
496-536: The gypsy moth or the spongy moth , is a species of moth in the family Erebidae native to Europe and Asia . Lymantria dispar is subdivided into several subspecies, with subspecies such as L. d. dispar and L. d. japonica being clearly identifiable without ambiguity. Lymantria dispar has been introduced to several continents and is now additionally found as an invasive species in Africa , North America and South America . The polyphagous larvae live on
527-607: The 16th century was used mostly to indicate the larva , usually in reference to devouring clothes. Moth larvae, or caterpillars , make cocoons from which they emerge as fully grown moths with wings. Some moth caterpillars dig holes in the ground, where they live until they are ready to turn into adult moths. Moths evolved long before butterflies; moth fossils have been found that may be 190 million years old. Both types of Lepidoptera are thought to have co-evolved with flowering plants , mainly because most modern species, both as adults and larvae, feed on flowering plants. One of
558-613: The ailanthus moth ( Samia cynthia group of species), the Chinese oak silkmoth ( Antheraea pernyi ), the Assam silkmoth ( Antheraea assamensis ), and the Japanese silk moth ( Antheraea yamamai ). The larvae of many species are used as food , particularly in Africa, where they are an important source of nutrition. The mopane worm, the caterpillar of Gonimbrasia belina , from the family Saturniidae,
589-440: The earliest known species that is thought to be an ancestor of moths is Archaeolepis mane . Its fossil fragments show scaled wings that are similar to caddisflies in their veining. Some moths, particularly their caterpillars , can be major agricultural pests in many parts of the world. Examples include corn borers and bollworms . The caterpillar of the spongy moth ( Lymantria dispar ) causes severe damage to forests in
620-728: The families Erebidae and Sphingidae , may be the key pollinators for some flowering plants in the Himalayan ecosystem. The roles of moths as pollinators have been studied less frequently than those of diurnal pollinators, but recent studies have established that moths are important, but often overlooked, nocturnal pollinators of a wide range of plants. Some researchers say it is likely that many plants thought to be dependent on bees for pollination also rely on moths, which have historically been less observed because they pollinate mainly at night. Moths frequently appear to circle artificial lights. The reason for this behavior (positive phototaxis )
651-515: The family Tineidae are commonly regarded as pests because their larvae eat fabric such as clothes and blankets made from natural proteinaceous fibers such as wool or silk . They are less likely to eat mixed materials containing some artificial fibers. There are some reports that they may be repelled by the scent of wood from juniper and cedar , by lavender , or by other natural oils; however, many consider this unlikely to prevent infestation. Naphthalene (the chemical used in mothballs )

#1733086179113682-411: The group is paraphyletic with respect to butterflies (suborder Rhopalocera) and neither subordinate taxon is used in modern classifications. Moths make up the vast majority of the order. There are approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal , although there are also crepuscular and diurnal species. While the butterflies form
713-474: The insect's name in its native area. The European native, and introduced North American, Lymantria dispar moths are considered to be the same subspecies, Lymantria dispar dispar . Confusion over the classification of species and subspecies exists. The U. S. Department of Agriculture defines the Asian subspecies as "any biotype of L. dispar possessing female flight capability", despite L. d. asiatica not being
744-464: The introduction of the species to North America, spongy moths have caused significant ecological damage. Over the past century, their range has expanded at an average rate of 21 km (13 mi) per year, resulting in the cumulative defoliation of 33,000,000 ha (82,000,000 acres) of forest between 1970 and 2013. The U.S. Forest Service allocates an average annual budget of $ 30 million toward control efforts. However, climate change has contributed to
775-641: The larvae of many different species of moths. Moths, like butterflies, bees and other more popularly recognized pollinating insects, serve an essential role as pollinators for many flowering plants, including species that bees do not visit. Nocturnal moths fly from flower to flower to feed on nectar during the night much as their diurnal relatives do during the day. A study conducted in the UK found moths dusted with pollen from 47 different plant species, including seven species largely ignored by bees. Some studies indicate that certain species of moths, such as those belonging to
806-425: The light source. Studies have found that light pollution caused by increasing use of artificial lights has either led to a severe decline in moth population in some parts of the world or has severely disrupted nocturnal pollination. [REDACTED] Quotations related to Moths at Wikiquote Spongy moth L. d. dispar L. d. asiatica L. d. japonica Lymantria dispar , also known as
837-487: The northeastern United States, where it is an invasive species . In temperate climates, the codling moth causes extensive damage, especially to fruit farms. In tropical and subtropical climates, the diamondback moth ( Plutella xylostella ) is perhaps the most serious pest of brassicaceous crops. Also in sub-Saharan Africa , the African sugarcane borer is a major pest of sugarcane, maize , and sorghum . Several moths in
868-482: The only accepted subspecies that is capable of flight. Traditionally, L. dispar has been referred to as "gypsy moth" even when referring to Japanese, Indian and Asiatic populations. The European subspecies ( Lymantria dispar dispar ) is native to temperate forests in western Europe . It had been introduced to the United States in 1869, and to Canada in 1912. The Asian subspecies ( Lymantria dispar asiatica )
899-507: The rise of angiosperms in the Cretaceous period. The modern English word moth comes from Old English moððe ( cf. Northumbrian mohðe ) from Common Germanic (compare Old Norse motti , Dutch mot , and German Motte all meaning 'moth'). Its origins are possibly related to the Old English maða meaning ' maggot ' or from the root of midge which until
930-600: The tussock-like tufts of hair on the caterpillars . The name Lymantria dispar is composed of two Latin-derived words. The generic name Lymantria means 'destroyer'. The species epithet dispar means 'to separate' in Latin; it refers to the sexual dimorphism observed in the male and female imagines . In July 2021 the Entomological Society of America decided to remove the name "gypsy moth" from its Common Names of Insects and Related Organisms List as "hurtful to
961-441: The upper part of the visual field, or on the horizon. When a moth encounters a much closer artificial light and uses it for navigation, the angle changes noticeably after only a short distance, in addition to being often below the horizon. The moth instinctively attempts to correct by turning toward the light, thereby causing airborne moths to come plummeting downward, and resulting in a spiral flight path that gets closer and closer to
