Dynastes Grantii
The western Hercules beetle (''Dynastes grantii'', often misspelled as "''granti''") is a species of rhinoceros beetle that lives in Arizona, New Mexico, Utah and parts of northern Mexico. This species is known for its grayish-white elytra, large size, and characteristic horn of the adult males. Description Adult body sizes of both sexes vary from 35 to 60mm (apex of elytra to apex of thoracic horn), with captive-reared individuals reaching up to 80mm. Coloration of the elytra varies from white to grayish-white, often with irregular black spots of various size and number. At high humidity levels, the elytra may appear black. ''Dynastes grantii'' is sexually dimorphic, with the females lacking the characteristic horns of the male. Life Cycle Like other Hercules beetle species, ''Dynastes grantii'' undergoes a six-stage life cycle from egg to adult, with three larval instars and a single pupal stage. The time from egg to pupal eclosion is estimated to take approximately two y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fraxinus
''Fraxinus'' (), common name, commonly called ash, is a genus of flowering plants in the olive and lilac family, Oleaceae. It contains 45–65 species of usually medium to large trees, mostly deciduous, though a number of Subtropics, subtropical species are evergreen. The genus is widespread across much of Europe, Asia, and North America. The leaf, leaves are opposite leaves, opposite (rarely in Whorl (botany), whorls of three), and mostly pinnate, pinnately compound, though simple in a few species. The seeds, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara (fruit), samara. Some ''Fraxinus'' species are Dioecy, dioecious, having male and female flowers on separate plants but sex in ash is expressed as a continuum between male and female individuals, dominated by unisexual trees. With age, ash may change their sexual function from predominantly male and hermaphrodite towards femaleness ; if grown as an ornamental and both sexes are present, ...

Dynastinae
Dynastinae or rhinoceros beetles are a subfamily of the scarab beetle family (Scarabaeidae). Other common names – some for particular groups of rhinoceros beetles – include Hercules beetles, unicorn beetles or horn beetles. Over 1500 species and 225 genera of rhinoceros beetles are known. Many rhinoceros beetles are well known for their unique shapes and large sizes. Some famous species are, for example, the Atlas beetle (''Chalcosoma atlas''), common rhinoceros beetle (''Xylotrupes ulysses''), elephant beetle (''Megasoma elephas''), European rhinoceros beetle (''Oryctes nasicornis''), Hercules beetle (''Dynastes hercules''), Japanese rhinoceros beetle or ''kabutomushi'' (''Allomyrina dichotoma''), ox beetle (''Strategus aloeus'') and the Eastern Hercules beetle (''Dynastes tityus''). Description and ecology The Dynastinae are among the largest of beetles, reaching more than in length, but are completely harmless to humans because they cannot bite or sting. So ...

Dynastes Tityus
''Dynastes tityus'', the eastern Hercules beetle, is a species of rhinoceros beetle native to the Eastern United States. The adult's elytra are green, gray or tan, with black markings, and the whole animal, including the male's horns, may reach in length. The larvae feed on decaying wood from various trees. Description Adults of both sexes are wide, and males are long, including a long horn (the pronotal horn) which projects forwards from the thorax of the male; a second horn (the clypeal horn) projects upwards from the head. ''Dynastes tityus'' is therefore "among the longest and heaviest beetles in the United States". The horns are used in battles between rival males competing for a mate; the size of the horn reflects the availability of food when the beetle was growing. Despite the size of the horns, ''Dynastes tityus'' is harmless to humans. The elytra are green, gray, or tan, usually with black mottling. The pattern of spots is unique to each individual.

Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Cambium
A cambium (plural cambia or cambiums), in plants, is a tissue layer that provides partially undifferentiated cells for plant growth. It is found in the area between xylem and phloem. A cambium can also be defined as a cellular plant tissue from which phloem, xylem, or cork grows by division, resulting (in woody plants) in secondary thickening. It forms parallel rows of cells, which result in secondary tissues. There are several distinct kinds of cambium found in plant stems and roots: * Cork cambium, a tissue found in many vascular plants as part of the periderm. * Unifacial cambium, which ultimately produces cells to the interior of its cylinder. * Vascular cambium, a lateral meristem in the vascular tissue of plants. Uses The cambium of many species of woody plants are edible; however, due to its vital role in the homeostasis and growth of woody plants, this may result in death of the plant if enough cambium is removed at once. The cambium can generally be eaten raw or cooke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
