Harrisina Americana
The grapeleaf skeletonizer (''Harrisina americana'') is a moth in the family Zygaenidae. It is widespread in the eastern half of the United States, and commonly noticed defoliating grapes, especially of the Virginia creeper (''Parthenocissus quinquefolia''). The western grapeleaf skeletonizer ('' Harrisina metallica'') is very similar to and slightly larger than ''H. americana,'' but their distributions are different. Members of this family all produce HCN (hydrogen cyanide) a potent antipredator toxin.Wikipedia: Zygaenidae Identification The adult has narrow black wings, usually held away from the body at rest, and a reddish collar. The wingspan is 18–28 mm, the length 8–12 mm. The larva has a dark head; the body is yellow with a complete black band across each abdominal segment. The larvae can reach up to 15 mm in length.Wagner Life history There are several generations per year in the south, and one in the north of its range. Eggs Eggs are lemon yellow, ...

Félix Édouard Guérin-Méneville
Félix Édouard Guérin-Méneville, also known as F. E. Guerin, (12 October 1799, in Toulon – 26 January 1874, in Paris) was a French entomologist. Life and work Guérin-Méneville changed his surname from Guérin in 1836. He was the author of the illustrated work ''Iconographie du Règne Animal de G. Cuvier 1829–1844'', a complement to the work of the zoologists Georges Cuvier and Pierre André Latreille, '' Le Règne Animal'', which illustrated only a selection of the animals covered. Cuvier was delighted with the work, saying that it would be very useful to readers, and that the illustrations were "as accurate as they were elegant". He also introduced silkworm The domestic silk moth (''Bombyx mori''), is an insect from the moth family Bombycidae. It is the closest relative of ''Bombyx mandarina'', the wild silk moth. The silkworm is the larva or caterpillar of a silk moth. It is an economically imp ...s to France, so they could be bred for the production of silk. ...

Moth
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.

Zygaenidae
The Zygaenidae moths are a family of Lepidoptera. The majority of zygaenids are tropical, but they are nevertheless quite well represented in temperate regions. Some of the 1000 or so species are commonly known as burnet or forester moths, often qualified by the number of spots, although other families also have 'foresters'. They are also sometimes called smoky moths. All 43 species of Australian zygaenids are commonly known as foresters and belong to the tribe Artonini. The only nonendemic species in Australia is ''Palmartona catoxantha'', a Southeast Asian pest species which is believed to be already present in Australia or likely to arrive soon.Tarmann, G.M. "Zygaenid moths of Australia. A revision of the Australian Zygaenidae". Description Larvae Larvae are stout and may be flattened. A fleshy extension of the thorax covers the head. Most feed on herbaceous plants, but some are tree feeders. Larvae in two subfamilies, Chalcosiinae and Zygaeninae, have cavities in whic ...

Parthenocissus Quinquefolia
''Parthenocissus quinquefolia'', known as Virginia creeper, Victoria creeper, five-leaved ivy, or five-finger, is a species of flowering vine in the grape family, Vitaceae. It is native to eastern and central North America, from southeastern Canada and the eastern United States west to Manitoba and Utah, and south to eastern Mexico and Guatemala. Etymology "Parthenocissus" is derived from Greek and means "virgin ivy".Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 292, 324 "Quinquefolia" means "five-leaved". "Quinque" – "five" and "folia" – "foliage", "leaves". Names The name "Virginia creeper", referring to one of its native locations, is also used for the whole genus ''Parthenocissus'', and for other species within the genus. The name ''Parthenocissus'' is from the Greek literally meaning "virgin ivy", and may derive from the common English name of this species. It is not closely related to the true ivy, ''Hedera ...

Harrisina Metallica
''Harrisina metallica'', the western grapeleaf skeletonizer, is a species of moth of the family Zygaenidae. It is found in the Southwestern United States, from California to Texas, north to Colorado and Utah and in northern Mexico. The wingspan is . Adults are on wing from April to October depending on the location. The larvae feed on grapes and species of ''Parthenocissus ''Parthenocissus'' , is a genus of tendril climbing plants in the grape family, Vitaceae. It contains about 12 species native to the Himalayas, eastern Asia and North America. Several are grown for ornamental use, notably ''P. henryana'', ''P. qu ...''. Some choose to call these larvae "grape worms" because of their impeccable taste for such a sweet fruit they're laid upon by their parents. The caterpillar also have stinging hairs that can cause rash or allergic reaction. They are in fact natures pest to precious to many grape vineyards affecting the crops yield for the season.

Hydrogen Cyanide
Hydrogen cyanide, sometimes called prussic acid, is a chemical compound with the formula HCN and structure . It is a colorless, extremely poisonous, and flammable liquid that boils slightly above room temperature, at . HCN is produced on an industrial scale and is a highly valued precursor to many chemical compounds ranging from polymers to pharmaceuticals. Large-scale applications are for the production of potassium cyanide and adiponitrile, used in mining and plastics, respectively. It is more toxic than solid cyanide compounds due to its volatile nature. Structure and general properties Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen. The tautomer of HCN is HNC, hydrogen isocyanide. Hydrogen cyanide is weakly acidic with a p''K''a of 9.2. It partially ionizes in water solution to give the cyanide anion, CN−. A solution of hydrogen cyanide in water, represented as HCN, is called ''hydrocyanic acid''. The salts of the cyan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seta
In biology, setae (singular seta ; from the Latin word for "bristle") are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Annelid setae are stiff bristles present on the body. They help, for example, earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (a group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. Crustaceans have mechano- and chemosensory setae. Setae are especially present on the mouthparts of crustaceans and can also be found on grooming limbs. In some cases, setae are modified into scale like structures. Setae on the legs of krill and other small crustaceans help them to gather phytoplankton. It captures them and allow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 metamo ...
