Brithys Crini
''Brithys crini'', the amaryllis borer, crinum borer, lily borer or Kew arches, is a moth of the family Noctuidae. It is a garden pest in parts of its range, as their larvae damage the stems and leaves of lilies, especially lilies of the family Amaryllidaceae. Range It is found in the coastal areas of the Mediterranean, south to South Africa. Furthermore, it is found in Japan and in Queensland and Northern Territory in Australia towards India and Sri Lanka. Description The wingspan of the moth is about 40 mm. Its head, thorax and forewings are very dark brown, but paler toward the wingtips. Sub-basal, median and postmedial indistinct waved lines are black. A curved submarginal ochreous line with ferrous colored lunuled found on each side of it. There is a marginal black lunule series. The hindwings are practically white. Tarsi bear black and white stripes. In Europe the adults are on the wing in July. Life stages There are several generations per year, though development ...

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 ...

Pancratium Maritimum
''Pancratium maritimum'', or sea daffodil, is a species of bulbous plant native to the Canary Islands and both sides of the Mediterranean region and Black Sea from Portugal, Morocco and the Balearic Islands east to Turkey, Syria, Israel and the Caucasus. In the parts of its range on the south Bulgarian and north Turkish and Georgian coasts of Black Sea. It is also naturalized in southern California, Bermuda and the Azores. ''Pancratium maritimum'' grows on beaches and coastal sand dunes, often with much of the leaves and scapes buried in the sand. Other vernacular names are sea lily, sand daffodil, sand lily and lily of St. Nicholas, (although it is not a true lily). The specific epithet ''maritimum'' means "of the sea". Description ''Pancratium maritimum'' is a bulbous perennial with a long neck and glaucous, broadly linear leaves, evergreen, but the leaves often die back during hot summers. Scape to . Flowers 3–15 in an umbel, up to long, white. Corona two-thirds as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hippeastrum Procerum
''Worsleya'' is a genus of Brazilian plants in the Amaryllis family, cultivated as an ornamental because of its showy flowers. There is only one known species, ''Worsleya procera'', native to eastern Brazil. It is endemic to a mesa called "Mount Cuca" 30 miles (52 km) north of Rio de Janeiro. Here the sickle-shaped leaves curve northward. When grown in the northern hemisphere, the leaves curve southward. It is one of the largest (around 1.5 meters high) and rarest members of the subfamily Amaryllidoideae (family Amaryllidaceae). This species is also known as the Empress of Brazil because of its origin in South America and in reference to the wife of Emperor Dom Pedro. It grows in very extreme and moist environments, and is commonly found near waterfalls in rich soil situated on granite rocks (which is why it is sometimes considered to be a lithophyte) and sunny places. However, it can be difficult to cultivate. It has plenty of needs, though it can exhibit great hardiness. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haemanthus
''Haemanthus'' is a Southern African genus of flowering plants in the family Amaryllidaceae, subfamily Amaryllidoideae. Members of the genus are known as blood lily and paintbrush lily. There are some 22 known species, native to South Africa, Botswana, Namibia, Lesotho and Eswatini. About 15 species occur in the winter rainfall region of Namaqualand and the Western Cape, the remainder being found in the summer rainfall region, with one species ''Haemanthus albiflos'' occurring in both regions. Description Most of the species have brush-like flowerheads enclosed in four or more membranous to fleshy spathe bracts which usually match the flower colour and, like sepals, protect the flowerheads from damage and desiccation. The flowers produce abundant nectar and pollen and a faint smell unattractive to humans. Fruits are mostly globose and when ripe, range through bright red, to pink, orange and white, and are usually aromatic. Three of the species'', H. albiflos'', ''H. deformis'' a ...

Hippeastrum
''Hippeastrum'' () is a genus of about 90 species and over 600 hybrids and cultivars of perennial herbaceous bulbous plants. They generally have large fleshy bulbs and tall broad leaves, generally evergreen, and large red or purple flowers. ''Hippeastrum'' is a genus in the family Amaryllidaceae (subfamily Amaryllidoideae, tribe Hippeastreae, and subtribe Hippeastrineae). The name ''Hippeastrum'', given to it by William Herbert, means "knight's star", although precisely what Herbert meant by the name is not certain. For many years there was confusion among botanists over the generic names ''Amaryllis'' and ''Hippeastrum'', one result of which is that the common name amaryllis is mainly used for cultivars of this genus, often sold as indoor flowering bulbs particularly at Christmas in the northern hemisphere. By contrast the generic name ''Amaryllis'' applies to bulbs from South Africa, usually grown outdoors. The genus is native to tropical and subtropical regions of the A ...

Clivia
''Clivia'' is a genus of monocot flowering plants native to southern Africa. They are from the family Amaryllidaceae, subfamily Amaryllidoideae. Common names are Natal lily or bush lily. They are herbaceous or evergreen perennial plants, with green, strap-like leaves. Individual flowers are more or less bell-shaped, occurring in umbels on a stalk above the foliage; colors typically range from yellow through orange to red. Many cultivars exist, some with variegated leaf patterns. Description Species of ''Clivia'' are found only in South Africa and Eswatini. They are typically forest undergrowth plants, adapted to low light (with the exception of '' C. mirabilis'' from the Western Cape). ''Clivia'' shares common features with the other members of the subfamily Amaryllidoideae. Individual flowers have three sepals and three petals, all very similar (although the sepals are typically narrower than the petals) and collectively called tepals. In ''Clivia'' the tepals are fused at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crinum
''Crinum'' is a genus of about 180 species of perennial plants that have large showy flowers on leafless stems, and develop from bulbs. They are found in seasonally moist areas, including marshes, swamps, depressions and along the sides of streams and lakes in tropical and subtropical areas worldwide. Description ''Crinum'' leaves are basal, typically long and strap-shaped, with colors ranging from light green to green. Cytological studies have shown some 27 species of Crinum to be diploid with a normal chromosome count of 2n = 22. Abilio Fernandes found that the Orange River '' Crinum bulbispermum'' had a count of 2n = 66, and some desert '' Crinum macowanii'' 2n = 44. These polyploid species produce seeds that are often parthenogenetic triploid or diploids, lack vigour and seldom grow to mature plants. Taxonomy , the World Checklist of Selected Plant Families lists 105 species of ''Crinum''. Amongst these are: *''Crinum americanum'' L. – southern swamplily, seven siste ...

Pupa
A pupa ( la, pupa, "doll"; plural: ''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'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosi ...

Aposematism
Aposematism is the advertising by an animal to potential predators that it is not worth attacking or eating. This unprofitability may consist of any defences which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These advertising signals may take the form of conspicuous coloration, sounds, odours, or other perceivable characteristics. Aposematic signals are beneficial for both predator and prey, since both avoid potential harm. The term was coined in 1877 by Edward Bagnall Poulton for Alfred Russel Wallace's concept of warning coloration. Aposematism is exploited in Müllerian mimicry, where species with strong defences evolve to resemble one another. By mimicking similarly coloured species, the warning signal to predators is shared, causing them to learn more quickly at less of a cost. A genuine aposematic signal that a species actually possesses chemical or physical defences is not the only way to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...
