Magicicada Septendecim
''Magicicada septendecim'', sometimes called the Pharaoh cicada or the 17-year locust, is native to Canada and the United States and is the largest and most northern species of Magicicada, periodical cicada with a 17-year lifecycle. Description Like other species included in ''Magicicada'', the insect's eyes and wing veins are reddish and its dorsal thorax is black. It is distinguished by broad orange stripes on its abdomen and a unique, high-pitched song said to resemble someone calling "weeeee-whoa" or "Pharaoh", features it shares with the newly discovered 13-year species ''Magicicada neotredecim''. Because of similarities between ''M. septendecim'' and the two closely related 13-year species ''M. neotredecim'' and ''Magicicada tredecim, M. tredecim'', the three species are often described together as "decim periodical cicadas." Life cycle Their median life cycle from egg to natural adult death is around seventeen years. However, their life cycle can range between thirteen ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals.

Botany
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning " pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – ed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brood X
Brood X (Brood 10), the Great Eastern Brood, is one of 15 broods of periodical cicadas that appear regularly throughout the eastern United States. The brood's first major emergence after 2021 is predicted to occur during 2038. Characteristics Every 17 years, Brood X cicada nymphs tunnel upwards ''en masse'' to emerge from the surface of the ground. The insects then shed their exoskeletons on trees and other surfaces, thus becoming adults. The mature cicadas fly, mate, lay eggs in twigs, and then die within several weeks. The combination of the insects' long underground life, their nearly simultaneous emergence from the ground in vast numbers and their short period of adulthood allows the brood to survive even massive predation. Brood X is endemic in Indiana, Ohio, southeastern Pennsylvania, Maryland, New Jersey, Delaware, East Tennessee, Virginia, Washington, DC, and other areas throughout the eastern United States. The brood contains three species, ''Magicicada septendecim'', ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
