Species are found in the northern half of Africa, and in Southwest and South Asia, often in arid or semi-arid areas. Adults are typically about long, with females generally larger than males of the same species. The genus includes both highly toxic species with contrasting aposematic colours and species with duller colours suitable for camouflage Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else.

Poekilocerus Pictus
''Poekilocerus pictus'', the painted grasshopper, aak grasshopper or ak grasshopper, is a fairly large and brightly coloured species of grasshopper found in India, Pakistan and Afghanistan, especially in drier regions. Both adults and nymphs are toxic; the nymphs are notorious for being able to squirt a jet of noxious liquid at up to around away when grasped. ''P. pictus'' was long regarded as the only ''Poekilocerus'' of the Indian subcontinent (other species are found in Southwest Asia and Africa), but in 2016 a new species, the overall yellowish-brown '' P. geniplanus'', was described from Chhattisgarh. Description Adults of ''P. pictus'' typically are long. The nymphs are greenish-yellow with fine black markings and small crimson spots. The mature grasshopper has canary yellow and turquoise or blue stripes on its body, green tegmina with yellow spots, and pale red hind wings. Feeding and toxicity Both adults and nymphs of ''P. pictus'' feed extensively on poisonous ''C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrgomorphidae
Pyrgomorphidae is a family of grasshoppers in the order Orthoptera; it is the only family in the superfamily Pyrgomorphoidea, with a pan-tropical distribution. Their name is probably derived from ''pyrgos'' (Greek: ''Πύργος'') meaning "tower": a reference to the form (''morph'') of the head in the type genus ''Pyrgomorpha'' and other genera. They may sometimes be known as "gaudy grasshoppers", due to the striking, often aposematic colouration of a number of genera; however many others are camouflaged or cryptic, including the genus ''Pyrgomorpha''.

Jean Guillaume Audinet-Serville
Jean Guillaume Audinet-Serville (; his name, before the French Revolution, Revolution, included a Nobiliary particle, particle: Audinet de Serville) was a French entomologist, born on 11 November 1775 in Paris. He died on 27 March 1858 in La Ferté-sous-Jouarre. He was introduced to entomology by Madame de Grostête-Tigny who was fascinated, like her husband, by chemistry and insects. Through her, Audinet-Serville met Pierre André Latreille (1762–1833). Latreille worked with him on the ''Dictionnaire des Insectes de l’Encyclopédie méthodique'' ("The Methodical Encyclopedia Dictionary of Insects"). Then, working with Guillaume-Antoine Olivier (1756–1814), he finished the book ''Faune française'' ("French Fauna") in 1830. Audinet-Serville is particularly known for his work on the Orthoptera. He published, ''Revue méthodique de l’ordre des Orthoptères'' ("Methodical Review of the Order of Orthoptera") which appeared in ''Annales des sciences naturelles'' in 1831. Then, ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Grasshopper
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are among what is possibly the most ancient living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. Grasshoppers are typically ground-dwelling insects with powerful hind legs which allow them to escape from threats by leaping vigorously. As hemimetabolous insects, they do not undergo complete metamorphosis; they hatch from an egg into a nymph or "hopper" which undergoes five moults, becoming more similar to the adult insect at each developmental stage. The grasshopper hears through the tympanal organ which can be found in the first segment of the abdomen attached to the thorax; while its sense of vision is in the compound eyes, the change in light intensity is perceived in the simple eyes (ocelli). At high population densities and under certain environmental conditions, some grasshopper species can change color and behavior and form swarms. Under ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Asia
Western Asia, West Asia, or Southwest Asia, is the westernmost subregion of the larger geographical region of Asia, as defined by some academics, UN bodies and other institutions. It is almost entirely a part of the Middle East, and includes Anatolia, the Arabian Peninsula, Iran, Mesopotamia, the Armenian Highlands, the Levant, the island of Cyprus, the Sinai Peninsula, and partly the Caucasus Region (Transcaucasia). The region is considered to be separated from Africa by the Isthmus of Suez in Egypt, and separated from Europe by the waterways of the Turkish Straits and the watershed of the Greater Caucasus. Central Asia lies to its northeast, while South Asia lies to its east. Twelve seas surround the region (clockwise): the Aegean Sea, the Sea of Marmara, the Black Sea, the Caspian Sea, the Persian Gulf, the Gulf of Oman, the Arabian Sea, the Gulf of Aden, the Red Sea, the Gulf of Aqaba, the Gulf of Suez, and the Mediterranean Sea. Western Asia covers an area of , with a pop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Asia
South Asia is the southern subregion of Asia, which is defined in both geographical and ethno-cultural terms. The region consists of the countries of Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka.;;;;;;;; Topographically, it is dominated by the Indian subcontinent and defined largely by the Indian Ocean on the south, and the Himalayas, Karakoram, and Pamir mountains on the north. The Amu Darya, which rises north of the Hindu Kush, forms part of the northwestern border. On land (clockwise), South Asia is bounded by Western Asia, Central Asia, East Asia, and Southeast Asia. The South Asian Association for Regional Cooperation (SAARC) is an economic cooperation organization in the region which was established in 1985 and includes all eight nations comprising South Asia. South Asia covers about , which is 11.71% of the Asian continent or 3.5% of the world's land surface area. The population of South Asia is about 1.9 billion or about one- ...
