Speckled Wood (butterfly)
The speckled wood (''Pararge aegeria'') is a butterfly found in and on the borders of woodland areas throughout much of the Palearctic realm. The species is subdivided into multiple subspecies, including ''Pararge aegeria aegeria'', ''Pararge aegeria tircis'', ''Pararge aegeria oblita'', and ''Pararge aegeria insula''. The color of this butterfly varies between subspecies. The existence of these subspecies is due to variation in morphology down a gradient corresponding to a geographic Cline (biology), cline. The background of the wings ranges from brown to orange, and the spots are either pale yellow, white, cream, or a tawny orange. The speckled wood feeds on a variety of grass species. The males of this species exhibit two types of mate locating behaviors: Territory (animal), territorial defense and patrolling. The proportion of males exhibiting these two strategies changes based on Ecology, ecological conditions. The monandrous female must choose which type of male can help her ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, 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. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cynodon Dactylon
''Cynodon dactylon'', commonly known as Bermuda grass, also known as couch grass in Australia and New Zealand, is a grass found worldwide. It is native to Europe, Africa, Australia and much of Asia. It has been introduced to the Americas. Contrary to its common name, it is not native to Bermuda and is in fact an abundant invasive species there. In Bermuda it has been known as "crab grass" (also a name for ''Digitaria sanguinalis''). Other names are ''Dhoob'', ''dūrvā'' grass, ''ethana'' grass, ''dubo'', dog grass, dog's tooth grass, Bahama grass, crab grass, devil's grass, couch grass, Indian ''doab'', ''arugampul'', grama, wiregrass and scutch grass. Hybrid species of Cynodon dactylon have been produced known as Cynodon dactylon x transvaalensis. These are Interspecific hybrids from cross-pollination of plants of different species. Vegetatively propagated Bermuda/couch hybrid varieties are developed by a selection of superior plants from established seeded or vegetatively prop ...

Malta
Malta, officially the Republic of Malta, is an island country in Southern Europe located in the Mediterranean Sea, between Sicily and North Africa. It consists of an archipelago south of Italy, east of Tunisia, and north of Libya. The two official languages are Maltese language, Maltese and English language, English. The country's capital is Valletta, which is the smallest capital city in the EU by both area and population. It was also the first World Heritage Site, World Heritage City in Europe to become a European Capital of Culture in 2018. With a population of about 542,000 over an area of , Malta is the world's List of countries and dependencies by area, tenth-smallest country by area and the List of countries and dependencies by population density, ninth-most densely populated.

Bromus
''Bromus'' is a large genus of grasses, classified in its own tribe Bromeae. They are commonly known as bromes, brome grasses, cheat grasses, or chess grasses. Estimates in the scientific literature of the number of species have ranged from 100 to 400, but plant taxonomists currently recognize around 160–170 species. ''Bromus'' is part of the cool-season grass lineage (subfamily Pooideae), which includes about 3300 species. Within Pooideae, ''Bromus'' is classified in tribe Bromeae (it is the only genus in the tribe). ''Bromus'' is closely related to the wheat-grass lineage (tribe Triticeae) that includes such economically important genera as ''Triticum'' (wheat), ''Hordeum'' (barley) and ''Secale'' (rye). Etymology The generic name ''Bromus'' is derived from the Latin ''bromos'', a borrowed word from the Ancient Greek (). and mean ''oats'', but seems to have referred specifically to '' Avena sativa'' (Hippocrates ''On Regimen in Acute Diseases'' 2.43, Dioscorides Me ...

Brachypodium Sylvaticum
''Brachypodium sylvaticum'', commonly known as false-brome, slender false brome or wood false brome, is a perennial grass native to Europe, Asia and Africa. Its native range includes most of Europe, northwestern Africa, Sudan and Eritrea, Western and Central Asia, the Indian subcontinent, China, Korea, Japan, Malesia, and New Guinea. The bunchgrass is most commonly found in forests and woodlands, preferring the shaded canopy, but may grow in open areas. It prefers well drained neutral and calcerous soils, and avoids wet conditions. Description ''Brachypodium sylvaticum'' is a tall tufted perennial bunchgrass that grows up to about a high. The drooping leaf blade of the plant is dark green, or bright-yellow green, flat and up to 12 mm wide with a fringe of hairs surrounding the edge of the leaf. The leaves do not have auricles. The leaf blade is joined to the hollow culm by the leaf sheath. This hairy sheath is open and surrounds the culm. The culm is pilose (long, soft ...

Brachypodium
''Brachypodium'' is a genus of plants in the grass family, widespread across much of Africa, Eurasia, and Latin America. The genus is classified in its own tribe Brachypodieae. Flimsy upright stems form tussocks. Flowers appear in compact spike-like racemes with 5-25 flowers on each short-stalked spikelet in summer. Leaves are flat or curved. According to a study published in 2010, there is evidence of ''Brachypodium'' and cattail (''Typha'' spp.) residues occurring on prehistoric human grinding tools dated 28,000 years ago from Bilancino in central Italy. Another contemporaneously published study stated that the grain residues resemble ''Brachypodium'', based on a comparison to two modern specimens: "Among these, the grains, which are slightly angular, with hardly visible centric, point-shaped hila and adequate dimensions (in the sample measuring 9–14 μm), appeared very similar to those of ''Brachypodium'' or related genera." ;Species * ''Brachypodium × ambrosii'' - Spai ...

Chrysalis
A pupa (; : pupae) is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as #Chrysalis, ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as #Cocoon, cocoons, nests, or Exoskeleton, shells. Position in life cycle The pupal stage follows the larval stage, or in some cases a prepupal stage, and precedes adulthood (''imago'' ...
