Eutachyptera
''Eutachyptera'' is a monotypic moth genus in the family Lasiocampidae. The genus was erected by William Barnes and James Halliday McDunnough in 1912. Its single species, ''Eutachyptera psidii'', was first described by Sallé in 1857. It is found in Mexico. Behaviour The caterpillars feed on the leaves of guava (''Psidium'' sp.) and oak. They live communally in large silken nests, which can extend to or more in length. They remain in the nests by day and leave at night to feed, laying a trail of pheromones to help them and their nest-mates navigate to and from feeding areas. Unusually among caterpillars, ''E. psidii'' larvae can remain active for as long as 18 days with no food, which they may have to do when their host trees lose their leaves in winter. Use of larvae and silk The larvae are among the caterpillars traded and eaten in Mexico. The silk nests were used by the Aztecs, Mixtecs and Zapotecs to make a paper-like fabric, which was a commercial item at the ti ...

Animalia
Animals are multicellular, eukaryotic organisms in the Biology, biological Kingdom (biology), kingdom Animalia (). With few exceptions, animals heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, have myocytes and are motility, able to move, can reproduce sexually, and grow from a hollow sphere of Cell (biology), cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million extant taxon, living animal species have been species description, described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and biological interaction, interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as ...

Social Caterpillars
The collective behaviors of social caterpillars falls into five general categories: collective and cooperative foraging, group defense against predators and parasitoids, shelter building, thermoregulation and substrate silking to enhance steadfastness. The most behaviorally sophisticated of the insect societies are found among the ants, termites, bees, and wasps. While these insects are technically classified as eusocial insects they are commonly referred to simply as the social insects. In this scheme of classification, other non-eusocial, gregarious species of insects are referred to as presocial, subsocial, quasisocial, or in some other manner that has the unfortunate consequence of suggesting that are not quite social. Yet a significant number of insect species that do not possess the defining criteria of eusociality are by any other standard of classification clearly social and it is in this sense of the term, that employed by zoologists in general, that larval aggregates of m ...

Taxa Named By William Barnes (entomologist)
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Oaxaca Valley
The Central Valleys () of Oaxaca, also simply known as the Oaxaca Valley, is a geographic region located within the modern-day state of Oaxaca in southeastern Mexico. In an administrative context, it has been defined as comprising the districts of Etla, Centro, Zaachila, Zimatlán, Ocotlán, Tlacolula and Ejutla. The valley, which is located within the Sierra Madre Mountains, is shaped like a distorted and almost upside-down “Y,” with each of its arms bearing specific names: the northwestern Etla arm, the central southern Valle Grande, and the Tlacolula arm to the east. The Oaxaca Valley was home to the Zapotec civilization, one of the earliest complex societies in Mesoamerica, and the later Mixtec culture. A number of important and well-known archaeological sites are found in the Oaxaca Valley, including Monte Albán, Mitla, San José Mogote and Yagul. Today, the capital of the state, the city of Oaxaca, is located in the central portion of the valley. History ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Moctezuma II
Moctezuma Xocoyotzin . ( – 29 June 1520), retroactively referred to in European sources as Moctezuma II, and often simply called Montezuma,Other variant spellings include Moctezuma, Motewksomah, Motecuhzomatzin, Moteuczoma, Motecuhzoma, Motēuczōmah and Muteczuma was the ninth emperor of the Aztec Empire (also known as the Mexica Empire), reigning from 1502 or 1503 to 1520. Through his marriage with Queen Tlapalizquixochtzin of Ecatepec, one of his two wives, he was also the king consort of that ''altepetl''. The first contact between the indigenous civilizations of Mesoamerica and Europeans took place during his reign. He was killed during the initial stages of the Spanish conquest of the Aztec Empire when Hernán Cortés, the Spanish conquistador, and his men seized the Aztecs, Aztec capital of Tenochtitlan. During his reign, the Aztec Empire reached its greatest size. Through warfare, Moctezuma expanded the territory as far south as Soconusco, Xoconosco in Chiapas and the ...

Zapotec Civilization
The Zapotec civilization ( "The People"; 700 BC–1521 AD) is an Indigenous peoples, indigenous Pre-Columbian era, pre-Columbian civilization that flourished in the Valley of Oaxaca in Mesoamerica. Archaeological evidence shows that their culture originated at least 2,500 years ago. The Zapotec archaeological site at the ancient city of Monte Albán has monumental buildings, Mesoamerican ballgame, ball courts, tombs and grave goods, including finely worked gold jewelry. Monte Albán was one of the first major cities in Mesoamerica. It was the center of a Zapotec state that dominated much of the territory which today is known as the Mexican state of Oaxaca. History Zapotec civilization originated in the Y-shaped Valley of Oaxaca, Central Valleys of Oaxaca in the late 6th century BC. The three valleys were divided among three differently-sized societies, separated by "no-man's-land" in the middle. The Oaxaca, Oaxaca, city of Oaxaca much later developed in that area. Archaeolo ...

Mixtec
The Mixtecs (), or Mixtecos, are Indigenous Mesoamerican peoples of Mexico inhabiting the region known as La Mixteca of Oaxaca and Puebla as well as La Montaña Region and Costa Chica of Guerrero, Costa Chica Regions of the state of Guerrero. The Mixtec culture was the main Mixtec civilization, which lasted from around 1500 BCE until being conquered by the Spanish in 1523. The Mixtec region is generally divided into three subregions based on geography: the Mixteca Alta (Upper Mixtec or Ñuu Savi Sukun), the Mixteca Baja (Lower Mixtec or Ñuu I'ni), and the La Mixteca, Mixteca Costa (Coastal Mixtec or Ñuu Andivi). The Alta is drier with higher elevations, while the Baja is lower in elevation, hot but dry, and the Costa is also low in elevation but much more humid and tropical. The Alta has seen the most study by archaeologists, with evidence for human settlement going back to the Archaic period in Mesoamerica, Archaic and Early Mesoamerican chronology#Preclassic Era or Form ...

Aztecs
The Aztecs ( ) were a Mesoamerican civilization that flourished in central Mexico in the post-classic period from 1300 to 1521. The Aztec people included different ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who dominated large parts of Mesoamerica from the 14th to the 16th centuries. Aztec culture was organized into city-states ('' altepetl''), some of which joined to form alliances, political confederations, or empires. The Aztec Empire was a confederation of three city-states established in 1427: Tenochtitlan, the capital city of the Mexica or Tenochca, Tetzcoco, and Tlacopan, previously part of the Tepanec empire, whose dominant power was Azcapotzalco. Although the term Aztecs is often narrowly restricted to the Mexica of Tenochtitlan, it is also broadly used to refer to Nahua polities or peoples of central Mexico in the prehispanic era, as well as the Spanish colonial era (1521–1821).

Guava
Guava ( ), also known as the 'guava-pear', is a common tropical fruit cultivated in many tropical and subtropical regions. The common guava '' Psidium guajava'' (lemon guava, apple guava) is a small tree in the myrtle family (Myrtaceae), native to Mexico, Central America, the Caribbean and northern South America. The name guava is also given to some other species in the genus '' Psidium'' such as strawberry guava ('' Psidium cattleyanum'') and to the pineapple guava, '' Feijoa sellowiana''. In 2019, 55 million tonnes of guavas were produced worldwide, led by India with 45% of the total. Botanically, guavas are berries. Etymology The term ''guava'' appears to have been in use since the mid-16th century. The name derived from the Taíno, a language of the Arawaks as for ''guava tree'' via the Spanish for . It has been adapted in many European and Asian languages, having a similar form. Origin and distribution Guavas originated from an area thought to extend from Mexic ...

Arthropoda
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an exoskeleton with a cuticle made of chitin, often mineralised with calcium carbonate, a body with differentiated ( metameric) segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired ventral nerve cords running through all segments and forming paired ganglia in each segment. Their heads are formed by fusion of varying numbers of segments, and their brains are formed by fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
