Caterpillars are the larval stage of members of the order Lepidoptera.
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.
Antennae, sometimes referred to as "feelers", are paired appendages used for sensing in arthropods.
In biology and medicine, a host is a larger organism that harbours a smaller organism; whether a parasitic, a mutualistic, or a commensalist guest (symbiont). The guest is typically provided with nourishment and shelter. Examples include animals playing host to parasitic worms, cells harbouring pathogenic (disease-causing) viruses, a bean plant hosting mutualistic (helpful) nitrogen-fixing bacteria. More specifically in botany, a host plant supplies food resources to micropredators, which have an evolutionarily stable relationship with their hosts similar to ectoparasitism. The host range is the collection of hosts that an organism can use as a partner.
The family Yponomeutidae are known as the ermine moths, with several hundred species, most of them in the tropics. The larvae tend to form communal webs, and some are minor pests in agriculture, forestry, and horticulture. Adult moths are minor pollinators.
The Zygaenidae moths are a family of Lepidoptera. The majority of zygaenids are tropical, but they are nevertheless quite well represented in temperate regions. Some of the 1000 or so species are commonly known as burnet or forester moths, often qualified by the number of spots, although other families also have 'foresters'. They are also sometimes called smoky moths.
The Prodoxidae are a family of moths, generally small in size and nondescript in appearance. They include species of moderate pest status, such as the currant shoot borer, and others of considerable ecological and evolutionary interest, such as various species of "yucca moths".
Baculoviridae is a family of viruses. Arthropods, among the most studied being Lepidoptera, Hymenoptera and Diptera, serve as natural hosts. Currently, 85 species are placed in this family, assigned to four genera.
The beet armyworm or small mottled willow moth is one of the best-known agricultural pest insects. It is also known as the asparagus fern caterpillar. It is native to Asia, but has been introduced worldwide and is now found almost anywhere its many host crops are grown. The voracious larvae are the main culprits. In the British Isles, where it is an introduced species and not known to breed, the adult moth is known as the small mottled willow moth.
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.
Coleophora is a very large genus of moths of the family Coleophoridae. It contains some 1,350 described species. The genus is represented on all continents, but the majority are found in the Nearctic and Palaearctic regions. Many authors have tried splitting the genus into numerous smaller ones, but most of these have not become widely accepted.
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.
Phthorimaea operculella, also known as the potato tuber moth or tobacco splitworm, is a moth of the family Gelechiidae. It is an oligophagous insect that feeds on the plant family Solanaceae and is especially known for being a major pest of potato crops. Currently farmers utilize insecticides, parasites, and sprinkler irrigation in order to prevent P. operculella from infesting their croplands.
Nepticulidae is a family of very small moths with a worldwide distribution. They are characterised by eyecaps over the eyes. These pigmy moths or midget moths, as they are commonly known, include the smallest of all living moths, with a wingspan that can be as little as 3 mm in the case of the European pigmy sorrel moth, but more usually 3.5–10 mm. The wings of adult moths are narrow and lanceolate, sometimes with metallic markings, and with the venation very simplified compared to most other moths.
Chrysiridia rhipheus, the Madagascan sunset moth, is a species of day-flying moth of the family Uraniidae. It is considered one of the most impressive and appealing-looking lepidopterans. Famous worldwide, it is featured in most coffee table books on Lepidoptera and is much sought after by collectors, though many older sources misspell the species name as "ripheus". The colours originate from optical interference in the iridescent parts of the wings, while the black parts are pigmented. Adults have a wingspan of 7–9 cm (2.8–3.5 in).
Hyblaeidae are the "teak moths", a family of insects in the Lepidopteran order. The two genera with about 18 species make up one of the two families of the Hyblaeoidea superfamily, which in the past has been included in the Pyraloidea. Recent phylogenetic studies find varying relationships of Hyblaeoidea among Ditrysian Lepidoptera: Mutanen et al. (2010) find the superfamily to group either with Pyraloidea, or – more often – with Thyridoidea or butterflies. The results of Wahlberg et al. (2013) and Heikilä et al. (2015) indicate a sister-group relationship with Pyraloidea.
Epermeniidae or the fringe-tufted moths is a family of insects in the lepidopteran order with about 14 genera. Previously they have been divided in two subfamilies Epermeniinae and Ochromolopinae but this is no longer maintained since the last group is probably hierarchically nested within the first. They are presently placed in their own superfamily but have previously been placed among the Yponomeutoidea or Copromorphoidea with which they share some features. Their systematic placement among the apoditrysian group "Obtectomera" is however uncertain. They show some morphological similarities to the "plume moths", for example the wing fringe has similar groups of scales. There are also some similarities to Schreckensteinioidea, for example spiny legs and at least in some species an open-network cocoon. The genus Thambotricha from New Zealand may be the sister group of all other extant members. The most important genera are Epermenia, Ochromolopis and Gnathifera. The group has been extensively revised and catalogued by Dr Reinhard Gaedike.
The diamondback moth, sometimes called the cabbage moth, is a moth species of the family Plutellidae and genus Plutella. The small, grayish-brown moth sometimes has a cream-colored band that forms a diamond along its back. The species may have originated in Europe, South Africa, or the Mediterranean region, but it has now spread worldwide.
Carposinoidea, the "fruitworm moths", is a superfamily of insects in the lepidopteran order. The superfamily is also known as Copromorphoidea, which is a junior synonym. These moths are small to medium-sized and are broad-winged bearing some resemblance to the superfamilies Tortricoidea and Immoidea. The antennae are often "pectinate" especially in males, and many species of these well camouflaged moths bear raised tufts of scales on the wings and a specialised fringe of scales at the base of the hindwing sometimes in females only; there are a number of other structural characteristics. The position of this superfamily is not certain, but it has been placed in the natural group of "Apoditrysia" "Obtectomera", rather than with the superfamilies Alucitoidea or Epermenioidea within which it has sometimes previously been placed, on the grounds that shared larval and pupal characteristics of these groups have probably evolved independently. It has been suggested that the division into two families should be abandoned.
Galleria mellonella, the greater wax moth or honeycomb moth, is a moth of the family Pyralidae. G. mellonella is found throughout the world. It is one of two species of wax moths, with the other being the lesser wax moth. G. mellonella eggs are laid in the spring, and they have four life stages. Males are able to generate ultrasonic sound pulses, which, along with pheromones, are used in mating. The larvae of G. mellonella are also often used as a model organism in research.
