Anisota Virginiensis
''Anisota virginiensis'', the pink-striped oakworm moth, is a species of silk moth of the family Saturniidae. Description The female's wings are purplish red with ochre-yellow. They have thin scales and are almost transparent. The male's wings are purplish brown with a large transparent space in the middle. The female is larger than the male. The wing span is 4.2 to 6.6 centimeters. Habitat The moth can be found across Canada from Nova Scotia to southeastern Manitoba, and in the United States. It lives in deciduous woodlands and suburbs. Biology Females release a pheromone which attracts males that swarm around her like bees. Mating occurs during the morning. It is a rapid process. The male and female stay together for the rest of the day and then the female finds a place to lay eggs, usually under oak leaves. Such mating swarms have been observed at carrion, where host plants may be higher quality due to the influx of nutrients associated with decomposition. The caterpillars ...

Dru Drury
Dru Drury (4 February 1724 – 15 December 1803) was a British collector of natural history specimens and an entomologist. He had specimens collected from across the world through a network of ship's officers and collectors including Henry Smeathman. His collections were utilized by many entomologists of his time to describe and name new species and is best known for his book ''Illustrations of natural history'' which includes the names and descriptions of many insects, published in parts from 1770 to 1782 with copperplate engravings by Moses Harris. Life Dru Drury was born in Lad Lane, Wood Street, London where his father, also Dru [also given as "Drew"] Drury (1688–1763), was a Freedom of the City of London, citizen, goldsmith and silversmith of the City of London, and his second wife Mary, daughter of Dr Hesketh, chaplain to Anne, Queen of Great Britain, Queen Anne. The elder Dru Drury's grandfather, William, Lord of the Manor of Colne, Cambridgeshire, Colne (Drurys mano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foliage
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light en ...

Moths Described In 1773
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995. The Lepidoptera: Form, function and diversity. Oxford, UK: Oxford University Press; 404 p. Although the rules for distinguishing moths from butterflies are not well est ...

Quercus Texana
''Quercus texana'', commonly known as Nuttall's oak, is a fast-growing, large deciduous oak tree. It is a tree growing up to 25 meters (83 feet) tall, with dark brown Bark (botany), bark. It has leaves with sharp pointed lobes somewhat similar to those of the Georgia oak (''Q. georgiana'') and pin oak (''Q. palustris''). It is fast-growing and usually has a pleasing red color in autumn, much more reliably so than the pin oak. This species was for years erroneously called ''Quercus nuttallii'', but it is now known as ''Q. texana''; this has created much confusion with Texas red oak, which was known as ''Q. texana'' but is now known as ''Q. buckleyi''. It is native to the south-central United States primarily in the lower Mississippi River Valley in Louisiana, Arkansas, Mississippi, Alabama, and western Tennessee. There are additional populations in eastern Texas, southeastern Oklahoma, southeastern Missouri, far western Kentucky, and the southernmost ti ...

Pest (organism)
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; snake Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes .

Wildlife Conservation
Wildlife conservation refers to the practice of protecting wild species and their habitats in order to maintain healthy wildlife species or populations and to restore, protect or enhance natural ecosystems. Major threats to wildlife include habitat destruction, degradation, fragmentation, overexploitation, poaching, pollution and climate change. The IUCN estimates that 27,000 species of the ones assessed are at risk for extinction. Expanding to all existing species, a 2019 UN report on biodiversity put this estimate even higher at a million species. It is also being acknowledged that an increasing number of ecosystems on Earth containing endangered species are disappearing. To address these issues, there have been both national and international governmental efforts to preserve Earth's wildlife. Prominent conservation agreements include the 1973 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the 1992 Convention on Biological Diversity (C ...

Overwintering In Insects
Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally (endothermic), insects must rely on external sources to provide their heat (ectothermic). Thus, insects persisting in winter weather must tolerate freezing or rely on other mechanisms to avoid freezing. Loss of enzymatic function and eventual freezing due to low temperatures daily threatens the livelihood of these organisms during winter. Not surprisingly, insects have evolved a number of strategies to deal with the rigors of winter temperatures in places where they would otherwise not survive. Two broad strategies for winter survival have evolved within Insecta as solutions to their inability to generate significant heat metabolically. Migration is a complete avoidance of the temperatures that pose a threat. An alternative t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hazel
The hazel (''Corylus'') is a genus of deciduous trees and large shrubs native to the temperate Northern Hemisphere. The genus is usually placed in the birch family Betulaceae,Germplasmgobills Information Network''Corylus''Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins .Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan . though some botanists split the hazels (with the hornbeams and allied genera) into a separate family Corylaceae. The fruit of the hazel is the hazelnut. Hazels have simple, rounded leaves with double-serrate margins. The flowers are produced very early in spring before the leaves, and are monoecious, with single-sex catkins. The male catkins are pale yellow and long, and the female ones are very small and largely concealed in the buds, with only the bright-red, 1-to-3 mm-long styles visible. The fruits are nuts long and 1–2 cm diameter, surrounded by an involucre (husk) which partly to fully encloses the nut. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birch
A birch is a thin-leaved deciduous hardwood tree of the genus ''Betula'' (), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech-oak family Fagaceae. The genus ''Betula'' contains 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species. They are a typically rather short-lived pioneer species widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates. Description Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates. The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. The fruit is a small samara, although the wings may be obscure in some species. They differ from the alders (''Alnus'', another genus in the family) in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
