Insect Migration
Insect migration is the seasonal movement of insects, particularly those by species of dragonflies, beetles, butterflies and moths. The distance can vary with species and in most cases, these movements involve large numbers of individuals. In some cases, the individuals that migrate in one direction may not return and the next generation may instead migrate in the opposite direction. This is a significant difference from bird migration. Definition All insects move to some extent. The range of movement can vary from within a few centimeters for some sucking insects and wingless aphids to thousands of kilometers in the case of other insects such as locusts, butterflies and dragonflies. The definition of migration is therefore particularly difficult in the context of insects. A behavior-oriented definition proposed is This definition disqualifies movements made in the search of resources and which are terminated upon finding the resource. Migration involves longer distance move ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysiridia Rhipheus
''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 . Dru Drury, who described the moth in 1773, placed it in the genus '' Papilio'', considering it a butterfly. Jacob Hübner placed it in the moth genus ''Chrysiridia'' in 1823. Later redescriptions led to junior synonyms such as ''Chrysiridia madagascariensis'' (Lesson, 1831). At first the moth was thought to be from China or Bengal, but was later found to be endemic to Madagascar. It is found throughout the year in most parts of the island, with peak popula ...

Sympetrum
''Sympetrum'' is a genus of small to medium-sized skimmer dragonflies, known as darters in the UK and as meadowhawks in North America. The more than 50 species predominantly live in the temperate zone of the Northern Hemisphere; no ''Sympetrum'' species is native to Australia. Most North American darters fly in late summer and autumn, breeding in ponds and foraging over meadows. Commonly, they are yellow-gold as juveniles, with mature males and some females becoming bright red on part or all of their bodies. An exception to this color scheme is the black darter (''Sympetrum danae''). The genus includes the following species: *'' Sympetrum ambiguum'' – blue-faced meadowhawk *''Sympetrum anomalum'' *'' Sympetrum arenicolor'' *'' Sympetrum baccha'' *'' Sympetrum chaconi'' *''Sympetrum commixtum'' *''Sympetrum cordulegaster'' *''Sympetrum corruptum'' – variegated meadowhawk *''Sympetrum costiferum'' – saffron-winged meadowhawk *''Sympetrum croceolum'' *''Symp ...

Libellula
''Libellula'' is a genus of dragonflies, commonly called skimmers, in the family Libellulidae, distributed throughout the temperate zone of the Northern Hemisphere. Most species are found in the United States, where they are the best-known large dragonflies, often seen flying over freshwater ponds in summer. Many have showy wing patterns. Overview The taxa ''Ladona'' (corporals) and ''Plathemis'' (whitetails) have been considered as synonyms of ''Libellula'', subgenera, or separate genera by different authorities.

Schistocerca Gregaria
The desert locust (''Schistocerca gregaria'') is a species of locust, a periodically swarming, short-horned grasshopper in the family Acrididae. They are found primarily in the deserts and dry areas of northern and eastern Africa, Arabia, and southwest Asia. During population surge years, they may extend north into parts of western Spain and southern Italy, south into Eastern Africa, and east in northern India. The desert locust shows periodic changes in its body form and can change in response to environmental conditions, over several generations, from a solitary, shorter-winged, highly fecund, non-migratory form to a gregarious, long-winged, and migratory phase in which they may travel long distances into new areas. In some years, they may thus form locust plagues, invading new areas, where they may consume all vegetation including crops, and at other times, they may live unnoticed in small numbers. During plague years, desert locusts can cause widespread damage to crops, as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Macroglossum Stellatarum
The hummingbird hawk-moth (''Macroglossum stellatarum'') is a species of hawk moth found across temperate regions of Eurasia. The species is named for its similarity to hummingbirds, as they feed on the nectar of tube-shaped flowers using their long proboscis while hovering in the air; this resemblance is an example of convergent evolution. The hummingbird hawk-moth was first described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae''. As of 2018, its entire genome and mitogenome have been sequenced. Distribution The hummingbird hawk-moth is distributed throughout the northern Old World from Portugal to Japan, but it breeds mainly in warmer climates (southern Europe, North Africa, and points east). Three generations are produced in a year in Spain. It is a strong flier, dispersing widely in the summer. However it rarely survives the winter in northern latitudes (e.g. north of the Alps in Europe, north of the Caucasus in Russia). Moths in the genus ''Hemari ...

Monarch Butterfly Migration
Monarch butterfly migration is the phenomenon, mainly across North America, where the subspecies '' Danaus plexippus plexippus'' migrates each summer and autumn to and from overwintering sites on the West Coast of California or mountainous sites in Central Mexico. Other subspecies perform minor migrations or none at all. This massive movement of butterflies has been called "one of the most spectacular natural phenomena in the world". The monarchs begin their southern migration from September to October. Eastern and northeastern populations, up to 500,000 monarch butterflies, migrate at this time. Originating in southern Canada and the United States, they travel to overwintering sites in central Mexico. The butterflies arrive at their roosting sites in November. They remain in their roosts during the winter months and then begin their northern migration in March. No individual butterfly completes the entire round trip. Female monarchs lay eggs for a subsequent generation during the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Painted Lady
The Australian painted lady (''Vanessa kershawi'') is a species of butterfly mostly confined to Australia, although westerly winds have dispersed it to islands east of Australia, including New Zealand. Debate surrounds the taxonomy of this species. Some believe that the Australian painted lady should be a subspecies of the painted lady (''Vanessa cardui'') due to the similarity in lifestyle and behaviour. Furthermore, the painted lady is found around the globe, but Australia is the only location in which it varies enough to be considered a separate species. However, due to the distinct genitalia of the males, and variation in colouration, many others consider the Australian painted lady to be a separate species. During spring, adult butterflies migrate south in large numbers from northern states of Queensland and New South Wales. To find mates, male Australian painted ladies exhibit territorial behaviour, which involves a male perching on vegetation in a sunny spot on a hillto ...
