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 The Mixtecs (), or Mixtecos, are indigenous Mesoamerican peoples ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

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''; plural 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. 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 set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oaxaca Valley
The Central Valleys ( es, Valles Centrales) of Oaxaca, also simply known as the Oaxaca Valley, is a geographic region located within the modern-day state of Oaxaca in southern 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, Oaxaca City, is located in the central portion of the valley. Histor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moctezuma II
Moctezuma Xocoyotzin ( – 29 June 1520; oteːkˈsoːmaḁ ʃoːkoˈjoːt͡sĩn̥), nci-IPA, Motēuczōmah Xōcoyōtzin, moteːkʷˈsoːma ʃoːkoˈjoːtsin variant spellings include Motewksomah, Motecuhzomatzin, Montezuma, Moteuczoma, Motecuhzoma, Motēuczōmah, Muteczuma, and referred to retroactively in European sources as Moctezuma II, was the ninth Emperor of the Aztec Empire (also known as 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 king consort of that ''altepetl''. The first contact between the indigenous civilizations of Mesoamerica and Europeans took place during his reign, and he was killed during the initial stages of the Spanish conquest of the Aztec Empire, when conquistador Hernán Cortés and his men fought to take over the Aztec capital Tenochtitlan. During his reign, the Aztec Empire reached its greatest size. Through warfare, Moctezuma expanded the ter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zapotec Civilization
The Zapotec civilization ( "The People"; 700 BC–1521 AD) was an indigenous 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, ball courts, magnificent 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 Central Valleys of Oaxaca in the late 6th century BC. The three valleys were divided among three different-sized societies, separated by “no-man’s-land” in the middle. The city of Oaxaca much later developed in that area. Archaeological evidence, such as burned temples and sacrificed war captives, suggests that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Regions of the state of Guerrero. The Mixtec Culture was the main Mixtec civilization, which lasted from around 1500 BC 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 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 Coasta 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 and Early Formative periods. The first urbanized sites emerged here. Long considered to be part of the larger Mixteca region, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aztecs
The Aztecs () were a Mesoamerican culture that flourished in central Mexico in the post-classic period from 1300 to 1521. The Aztec people included different Indigenous peoples of Mexico, ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl, 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, city-state of the Mexica or Tenochca; Texcoco (altepetl), Texcoco; and Tlacopan, previously part of the Tepanec empire, whose dominant power was Azcapotzalco (altepetl), Azcapotzalco. Although the term Aztecs is often narrowly restricted to the Mexica of Tenochtitlan, it is also broadly used to refer to Nahuas, Nahua polities or peoples of central Pre-Columbian Mexico, Mexico in the preh ...

Guava
Guava () 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. Types The most frequently eaten species, and the one often simply referred to as "the guava", is the apple guava ('' Psidium guayava''). Guavas are typical Myrtoideae, with tough dark heavy leaves that are opposite, simple, elliptic to ovate, and long. The flowers are white, with five petals and numerous stamens. The fruits are many-seeded berries. Etymology The term ''guava'' appears ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropoda
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. 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. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system.
