Lepidoptera Migration
Many populations of Lepidoptera (butterflies or moths) migrate, sometimes long distances, to and from areas which are only suitable for part of the year. Lepidopterans migrate on all continents except Antarctica, including from or within subtropical and tropical areas. By migrating, these species can avoid unfavorable circumstances, including weather, food shortage, or over-population. In some lepidopteran species, all individuals migrate; in others, only some migrate. The best-known lepidopteran migration is that of the eastern population of the monarch butterfly which migrates from southern Canada to wintering sites in central Mexico. In late winter/early spring, the adult monarchs leave the Transvolcanic mountain range in Mexico for a more northern climate. Mating occurs and the females begin seeking out milkweed to lay their eggs, usually first in northern Mexico and southern Texas. The caterpillars hatch and develop into adults that move north, where more offspring can go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Euploea Sylvester
''Euploea sylvester'', the double-branded crow, also known as the two-brand crow in Australia, is a butterfly found in South Asia, Southeast Asia and parts of Australia that belongs to the crows and tigers, that is, the danaid group of the brush-footed butterflies family. Several races of the butterfly are recognized. Race ''pelor'' is found in Australia. Subspecies The subspecies of Euploea sylvester are- *''E. s. sylvester'' - Cape York - Rockhampton, Torres Strait Is. *''E. s. coreta'' (Godart, 1819) - Sri Lanka, S.India *''E. s. hopei'' (Felder & Felder, 1865) - Sikkim - Burma, Assam, Indo-China, Peninsular Malaya *''E. s. swinhoei'' - Taiwan *''E. s. pelor'' Doubleday, 1847 - NW.Australia, Northern Territory Description In shape, colour, and markings, it very closely resembles ''Euploea core''. Males, however, can be distinguished at once by the presence of two brands instead of a single one on the forewing. Of the females Lionel de Nicéville says, females of ''E. cor ...

Helicoverpa Armigera
''Helicoverpa armigera'' is a species of Lepidoptera in the family Noctuidae. It is known as the cotton bollworm, corn earworm, Old World (African) bollworm, or scarce bordered straw (the lattermost in the UK, where it is a migrant). The larvae feed on a wide range of plants, including many important cultivated crops. It is a major pest in cotton and one of the most polyphagous and cosmopolitan pest species. It should not be confused with the similarly named larva of the related species ''Helicoverpa zea''. Distribution This species comprises two sub-species: ''Helicoverpa armigera armigera'' is native and widespread in central and southern Europe, temperate Asia and Africa; ''Helicoverpa armigera conferta'' is native to Australia, and Oceania. The former sub-species has also recently been confirmed to have successfully invaded Brazil and has since spread across much of South America and reached the Caribbean. It is a migrant species, able to reach Scandinavia and other northern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysodeixis Chalcites
The tomato looper or golden twin-spot moth ''(Chrysodeixis chalcites)'' is a moth of the family Noctuidae, subfamily Plusiinae. It mainly lives in southern Europe, the Levant and tropical Africa, but can be seen migrating across much of Europe. In 2013, it was spotted in Canada. It is an important horticultural pest in New Zealand. The length of the forewings is 15–18 mm. The moth flies from June to October. The larvae feed on various herbaceous plants, such as ''Echium vulgare'', ''Apium'', ''Rubus'', tomato, '' Fragaria'' and tobacco which is why it is perceived as a pest. ''Chrysodeixis chalcites'' and '' Chrysodeixis eriosoma'' moths cannot be separated morphologically and they may be sibling species. They are distinguished by DNA, pheromones and geographic origin, as ''C. chalcites'' is found in the palearctic and ''C. eriosoma'' in the tropics and subtropics. The literature referring to ''C. chalcites'' in southern and eastern Asia or Oceania may actually refer t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galleria Mellonella
''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. The greater wax moth is well known for its Parasitism, parasitization of honeybees and their hives. Because of the economic loss caused by this species, several control methods including heat treatment and chemical fumigants such as carbon dioxide have been used. The caterpillar of ''G. mellonella'' has attracted interest for its ability to degrade Polyethylene, polyethylene plastic. Geographic range ''G. mellonella'' was first reported as a pest in Asia, but then spread to northern Africa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adventive Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diapause
In animal dormancy, diapause is the delay in development in response to regular and recurring periods of adverse environmental conditions.Tauber, M.J., Tauber, C.A., Masaki, S. (1986) ''Seasonal Adaptations of Insects''. Oxford University Press It is a physiological state with very specific initiating and inhibiting conditions. The mechanism is a means of surviving predictable, unfavorable environmental conditions, such as temperature extremes, drought, or reduced food availability. Diapause is observed in all the life stages of arthropods, especially insects. Embryonic diapause, a somewhat similar phenomenon, occurs in over 130 species of mammals, possibly even in humans, and in the embryos of many of the oviparous species of fish in the order Cyprinodontiformes. Activity levels of diapausing stages can vary considerably among species. Diapause may occur in a completely immobile stage, such as the pupae and eggs, or it may occur in very active stages that undergo extensive migrat ...

Aestivation
Aestivation ( la, aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. It takes place during times of heat and dryness, the hot dry season, which are often the summer months. Invertebrate and vertebrate animals are known to enter this state to avoid damage from high temperatures and the risk of desiccation. Both terrestrial and aquatic animals undergo aestivation. Fossil records suggest that aestivation may have evolved several hundred million years ago. Physiology Organisms that aestivate appear to be in a fairly "light" state of dormancy, as their physiological state can be rapidly reversed, and the organism can quickly return to a normal state.

Hibernation
Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months. Although traditionally reserved for "deep" hibernators such as rodents, the term has been redefined to include animals such as bears and is now applied based on active metabolic suppression rather than any absolute decline in body temperature. Many experts believe that the processes of daily torpor and hibernation form a continuum and utilise similar mechanisms. The equivalent during the summer months is aestivation. Hibernation functions to conserve energy when sufficient food is not available. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. Hibernation may last days, weeks, or months—depending on the species, ambient temperature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascia Monuste
''Ascia'' is a genus of butterflies in the family Pieridae. It is monotypic, being represented by the single species ''Ascia monuste'', commonly known as the great southern white, In this species the sexes may differ with the female being either light or dark colored. It is found from the Atlantic and Gulf coasts of the United States, and south to Argentina. It is migratory along the south-eastern coast of the United States, with strays to Maryland, Kansas, and Colorado. Larvae have distinct body segments within which there appears to be four to six subsegments. They are purplish-green with two longitudinal, greenish-yellow stripes on each side and the dorsal side. When full-grown, they are approximately one and a quarter inches long. The wingspan in adults is 63–86 mm. Adults are on wing all year round in southern Texas, peninsular Florida and along the Gulf Coast. ''A. monuste'' is a migrating species that moves in one direction within its life span and does not return ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierid
The Pieridae are a large family of butterflies with about 76 genera containing about 1,100 species, mostly from tropical Africa and tropical Asia with some varieties in the more northern regions of North America and Eurasia.DeVries P. J. in Levin S.A. (ed) 2001 The Encyclopaedia of Biodiversity. Academic Press. Most pierid butterflies are white, yellow, or orange in coloration, often with black spots. The pigments that give the distinct coloring to these butterflies are derived from waste products in the body and are a characteristic of this family.Carter, David (2000). ''Butterflies and Moths''. The family was created by William John Swainson in 1820. The name "butterfly" is believed to have originated from a member of this family, the brimstone, ''Gonepteryx rhamni'', which was called the "butter-coloured fly" by early British naturalists. The sexes usually differ, often in the pattern or number of the black markings. The larvae ( caterpillars) of a few of these species, s ...

Tirumala Limniace
''Tirumala limniace'', the blue tiger, is a butterfly found in South Asia, and Southeast Asia that belongs to the crows and tigers, that is, the danaid group of the brush-footed butterfly family. This butterfly shows gregarious migratory behaviour in southern India. In some places, it may be found in congregations with Danaus genutia, Tirumala septentrionis, Euploea sylvester, Euploea core, Parantica aglea, and at high elevations, with Parantica nilgiriensis, on Crotalaria. Description Tirumala limniace is a large butterfly with wide wings. It has a wingspan of 90 to 100 millimeters, with the males being smaller than the females. The upper side of the wing is dark brown to black and patterned with bluish-white, semi-transparent spots and lines. The blue of the bluish-white spots consists of the pigment pterobilin. In general, all butterflies can directly absorb heat from the sun via their wings to facilitate autonomous flight. Studies on blue tiger butterflies show that high ...
