Phasis Thero
''Phasis thero'', the silver arrowhead or hooked copper, is a butterfly of the family Lycaenidae. It is found in South Africa. The wingspan is 31–46 mm for males and 38–47 mm females. Adults of subspecies ''P. t. thero'' are on wing from September to November and again from March to May in two generations. Adults of subspecies ''P. t. cedarbergae'' are on wing from October to November and probably also in autumn. The larvae feed on ''Rhus undulata'' and ''Melianthus major''. Larvae have been found inside hollow stems of their food plant, but also in nests of '' Crematogaster peringueyi'' ants at the base of these stems.

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. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterfly
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the Order (biology), order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily (zoology), superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo Holometabolism, complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycaenidae
Lycaenidae is the second-largest family of butterflies (behind Nymphalidae, brush-footed butterflies), with over 6,000 species worldwide, whose members are also called gossamer-winged butterflies. They constitute about 30% of the known butterfly species. The family comprises seven subfamilies, including the blues (Polyommatinae), the coppers (Lycaeninae), the hairstreaks (Theclinae), and the harvesters (Miletinae). Description, food, and life cycle Adults are small, under 5 cm usually, and brightly coloured, sometimes with a metallic gloss. Larvae are often flattened rather than cylindrical, with glands that may produce secretions that attract and subdue ants. Their cuticles tend to be thickened. Some larvae are capable of producing vibrations and low sounds that are transmitted through the substrates they inhabit. They use these sounds to communicate with ants.Pierce, N. E.; Braby, M. F.; Heath, A.; Lohman, D. J.; Mathew, J.; Rand, D. B. & Travassos, M. A. (2002)"The eco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically extent, is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is distance between the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stood at and owned one of the largest wingspans at . Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, independently of wing shape or sweep. Implications for aircraft design and anima ...

Rhus
Sumac ( or ), also spelled sumach, is any of about 35 species of flowering plants in the genus ''Rhus'' and related genera in the cashew family (Anacardiaceae). Sumacs grow in subtropical and temperate regions throughout the world, including East Asia, Africa, and North America. Sumac is used as a spice, as a dye, and in medicine. Description Sumacs are dioecious shrubs and small trees in the family Anacardiaceae that can reach a height of . The leaves are usually pinnately compound, though some species have trifoliate or simple leaves. The flowers are in dense panicles or spikes long, each flower very small, greenish, creamy white or red, with five petals. The fruits are reddish, thin-fleshed drupes covered in varying levels of hairs at maturity and form dense clusters at branch tips, sometimes called sumac bobs. Sumacs propagate both by seed (spread by birds and other animals through their droppings), and by new shoots from rhizomes, forming large clonal colonies. Taxonomy ...

Melianthus Major
''Melianthus major'', the giant honey flower or ''kruidjie-roer-my-nie'' (Afrikaans for 'herb-touch-me-not'), is a species of flowering plant in the family Francoaceae. It is an evergreen suckering shrub, endemic to South Africa and naturalised in India, Australia and New Zealand. It grows to tall by wide, with pinnate blue-green leaves long, which have a distinctive musky odour. Dark red, nectar-laden flower spikes, in length, appear in spring, followed by green pods. All parts of the plants are poisonous. The Latin binomial ''Melianthus major'' literally means "large honey flower". The plant is also sometimes called ''honeybush'' ( along with many other plants)''.'' In cultivation this plant requires a sheltered location and may also need a protective winter mulch in temperate regions. It has gained the Royal Horticultural Society's Award of Garden Merit.

Crematogaster Peringueyi
''Crematogaster peringueyi'' is a southern African arboreal species of ant. They are commonly known as the black cocktail ant or swartwipgatmier (Afrikaans) for their colour and habit of arching their abdomens when alarmed. Habits They make their nests in old ''Protea'' flowers, dead, hollow branches, and under tree bark, also making nests constructed of well-chewed vegetable matter with the consistency of papier-mâché. The outer walls of these nests are blackened by the salivary secretions, and are thin, with the interior divided into irregular, connected cells, like a coarse sponge. These more or less spherical nests, ranging in diameter from 10–30 cm, are built in a fork or among the branches, some of the branches passing through the nest. Workers are glossy black and 3–5 mm long, and the larger queen is about 8 mm long, both having heart-shaped abdomens. Defense Pheromone alarms are common among the social Hymenoptera. Some of these have been chemicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Peninsula
The Cape Peninsula ( af, Kaapse Skiereiland) is a generally mountainous peninsula that juts out into the Atlantic Ocean at the south-western extremity of the African continent. At the southern end of the peninsula are Cape Point and the Cape of Good Hope. On the northern end is Table Mountain, overlooking Table Bay and the city bowl of Cape Town, South Africa. The peninsula is 52 km long from Mouille point in the north to Cape Point in the south. The Peninsula has been an island on and off for the past 5 million years, as sea levels fell and rose with the Glacial period, ice age and interglacial global warming cycles of, particularly, the Pleistocene. The last time that the Peninsula was an island was about 1.5 million years ago. Soon afterwards it was joined to the mainland by the Geology of Cape Town#Tertiary to Recent events, emergence from the sea of the sandy area now known as the Cape Flats. The towns and villages of the Cape Peninsula and Cape Flats, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lambert's Bay
Lambert's Bay is a small fishing town in the Western Cape province of South Africa situated north of Cape Town. It is part of the Cederberg Municipality.
