Lepidoptera is an order of insects that includes butterflies and moths. About 180,000 species of the Lepidoptera are described, in 126 families and 46 superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most species-rich orders, along with the Hymenoptera, Diptera, and Coleoptera.
A pupa is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence.
The luna moth, also called the American moon moth, is a Nearctic moth in the family Saturniidae, subfamily Saturniinae, a group commonly named the giant silk moths.
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 subfamily 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 Arctiinae refers to this hairiness. Some species within the Arctiinae have the word "tussock"' in their common names because they have been misidentified as members of the Lymantriinae subfamily based on the characteristics of the larvae.
Saturniidae, members of which are commonly named the 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.
Hyalophora cecropia, the cecropia moth, is North America's largest native moth. It is a member of the family Saturniidae, or giant silk moths. Females have been documented with a wingspan of five to seven inches or more. These moths can be found all across North America as far west as Washington and north into the majority of Canadian provinces. Cecropia moth larvae are most commonly found on maple trees, but they have also been found on cherry and birch trees among many others. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
Orgyia antiqua, the rusty tussock moth or vapourer, is a moth in the family Erebidae.
Euchaetes egle, the milkweed tiger moth or milkweed tussock moth, is a moth in the family Erebidae and the tribe Arctiini, the tiger moths. The species was first described by Dru Drury in 1773. It is a common mid- through late summer feeder on milkweeds and dogbane. Like most species in this family, it has chemical defenses it acquires from its host plants, in this case, cardiac glycosides. These are retained in adults and deter bats, and presumably other predators, from feeding on them. Only very high cardiac glycoside concentrations deterred bats, however. Adults indicate their unpalatability to bats with ultrasonic clicks from their tymbal organs.
Halysidota tessellaris, also called the pale tiger moth, banded tussock moth, and tessellated halisidota, is in the family Erebidae and the tribe Arctiini, the tiger moths. The species was first described by James Edward Smith in 1797. Like many related species, adult moths have chemical defenses acquired from its host plants, in this case, alkaloids. Larval behaviors suggest that they are chemically protected; they have not been analyzed for alkaloid content.
Lophocampa caryae, the hickory tiger moth, hickory tussock moth, or hickory halisidota, is a moth in the family Erebidae and the tribe Arctiini, the tiger moths. The species is widely distributed in the eastern half of North America. In other species in this family, the caterpillars acquire chemical defenses from their host plants, so they are potentially toxic or unpalatable, but despite anecdotal claims that this species may also be venomous, no venom has yet been isolated or identified; adverse reactions are characterized as contact dermatitis.
Orgyia leucostigma, the white-marked tussock moth, is a moth in the family Erebidae. The species was first described by James Edward Smith in 1797. The caterpillar is very common especially in late summer in eastern North America, extending as far west as Texas, California, and Alberta.
The saddleback caterpillar is the larva of a species of moth native to eastern North America. It is also found in Mexico. The species belongs to the family of slug caterpillars, Limacodidae.
Halysidota is a genus of moths in the family Erebidae. The genus was erected by Jacob Hübner in 1819.
Estigmene acrea, the salt marsh moth or acrea moth, is a moth in the family Erebidae. The species was first described by Dru Drury in 1773. It is found in North America, the Democratic Republic of the Congo, Kenya, Colombia, Mexico.
The external morphology of Lepidoptera is the physiological structure of the bodies of insects belonging to the order Lepidoptera, also known as butterflies and moths. Lepidoptera are distinguished from other orders by the presence of scales on the external parts of the body and appendages, especially the wings. Butterflies and moths vary in size from microlepidoptera only a few millimetres long, to a wingspan of many inches such as the Atlas moth. Comprising over 160,000 described species, the Lepidoptera possess variations of the basic body structure which has evolved to gain advantages in adaptation and distribution.
Lophocampa maculata, the Yellow-spotted tussock moth, mottled tiger or spotted halisidota, is a moth of the family Erebidae and the tribe Arctiini, the tiger moths. The species was first described by Thaddeus William Harris in 1841. It is found across Canada, the western parts of the United States, south in the Appalachians to South Carolina and Kentucky.
Nyctemera annulata, the magpie moth, is a moth of the family Erebidae. The species was first described by Jean Baptiste Boisduval in 1832. It is endemic to New Zealand and found in all parts of the country.
Cadra figulilella, the raisin moth, is a moth of the family Pyralidae. The raisin moth is known most commonly as a pest that feeds on dried fruits, such as the raisin and date. It covers a range that includes much of the world, primarily situating itself in areas of California, Florida, the Eastern Mediterranean region, and some parts of Africa, Australia, and South America. The moth prefers to live in a hot, arid climate with little moisture and plentiful harvest for its larvae to feed on. Study of this species is important due to the vast amount of economic damage it causes yearly and worldwide to agriculture crops.
Gynaephora rossii, in English known as Ross' tussock moth, is a species of tussock moth in the family Erebidae. It is widespread in the tundras and highlands of the Holarctic. It has large, furry caterpillars which seem to eat mostly saxifrages.
Trabala pallida is a species of moth in the family Lasiocampidae. They can be found from Southeast China, south throughout Thailand and most of Sundaland. One subspecies is Trabala pallida montana.
