Anisomorpha Buprestoides
''Anisomorpha buprestoides'', the southern two-striped walkingstick, devil rider, or musk mare, is a stick insect (order Phasmatodea: otherwise known as "phasmids" or walkingsticks) which occurs throughout the southeastern United States. ''Anisomorpha buprestoides'' is a large, stout (for a stick insect) brown phasmid with three conspicuous longitudinal black stripes. Females average in length; males are smaller and more slender, averaging . Defense This species, and another in the same genus ('' Anisomorpha ferruginea'', whose range is more west and north, but may overlap with ''A. buprestoides'') is particularly well known for its very potent chemical defense spray which it deploys from a pair of glands which open at the front of its thorax. The "Devil rider" name for this insect likely comes from this defense, as well as the fact that they are most frequently encountered in the late summer and fall when they are active adults at a time when almost all of them are found in mat ...

Caspar Stoll
Caspar Stoll (Hesse-Kassel, probably between 1725 and 1730 – Amsterdam, December 1791) was a naturalist and entomologist, best known for the completion of ''De Uitlandsche Kapellen'', a work on butterflies begun by Pieter Cramer. He also published several works of his own on other insect groups. Stoll's 1787 publication on stick insects, mantises, and their relatives is also well known. It was translated into French in 1813. Life Aside from official records, few biographical details are known. Caspar Stoll was born in Hesse-Kassel but lived most of his life in The Hague and Amsterdam. In the latter, he worked as a functionary (either a clerk or a porter) at the Admiralty of Amsterdam He married his first wife, Maria Sardijn, on 18 January 1761, they married in a church in Scheveningen. Her brother was a tax collector and a notary. Stoll appears to have worked for a notary as well: several times he put his signature as a witness. They had four children baptised in The Hague. Th ...

Dolichodial
Dolichodial is a natural chemical compound with two aldehyde groups, which belongs to the group of iridoid Iridoids are a type of monoterpenoids in the general form of cyclopentanopyran, found in a wide variety of plants and some animals. They are biosynthetically derived from 8-oxogeranial. Iridoids are typically found in plants as glycosides, mos ...s. Chemistry It has in its five-membered ring three asymmetric carbon atoms and accordingly exists in four diastereomeric pairs of enantiomers. The pairs with a different stereochemistry of dolichodial are called anisomorphal and peruphasmal.

Insects Of North America
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from egg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phasmatodea
The Phasmatodea (also known as Phasmida, Phasmatoptera or Spectra) are an order of insects whose members are variously known as stick insects, stick-bugs, walking sticks, stick animals, or bug sticks. They are also occasionally referred to as Devil's darning needles, although this name is shared by both dragonflies and crane flies. They can be generally referred to as phasmatodeans, phasmids, or ghost insects, with phasmids in the family Phylliidae called leaf insects, leaf-bugs, walking leaves, or bug leaves. The group's name is derived from the Ancient Greek ', meaning an apparition or phantom, referring to their resemblance to vegetation while in fact being animals. Their natural camouflage makes them difficult for predators to detect; still, many species have one of several secondary lines of defense in the form of startle displays, spines or toxic secretions. Stick insects from the genera ''Phryganistria'', ''Ctenomorpha'', and ''Phobaeticus'' include the world's longe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Journal Of Natural Products

It is co-published by the American Society of Pharmacognosy and the American Chemical Society. The editor-in-chief is Philip J. Proteau (Oregon State University). History The journal was established in 1938 as ''Lloydia'', published by the Lloyd Library and Museum, and obtained its present title in 1979. It has been the official journal of the American Society of Pharmacognosy since 1961. Originally a quarterly publication, it became a bimonthly journal in 1975, and has appeared monthly since 1992.

Leaf Beetle
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research. Leaf beetles are partially recognizable by their tarsal formula, which appears to be 4-4-4, but is actually 5-5-5 as the fourth tarsal segment is very small and hidden by the third. As with many taxa, no single character defines the Chrysomelidae; instead, the family is delineated by a set of characters. Some lineages are only distinguished with difficulty from longhorn beetles (family Cerambycidae), namely by the antennae not arising from frontal tubercles. Adult and larval leaf beetles feed on all sorts of plant tissue, and all species are fully herbivorous. Many are serious pests of cultivated plants, f ...

Biosynthetic Pathway
Metabolism (, from el, μεταβολή ''metabolē'', "change") is the set of life-sustaining chemical reactions in organisms. The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks for proteins, lipids, nucleic acids, and some carbohydrates; and the elimination of metabolic wastes. These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their structures, and respond to their environments. The word metabolism can also refer to the sum of all chemical reactions that occur in living organisms, including digestion and the transportation of substances into and between different cells, in which case the above described set of reactions within the cells is called intermediary (or intermediate) metabolism. Metabolic reactions may be categorized as ''catabolic'' – the ''breaking down'' of compounds (for example, of glucose to pyruvate by cel ...

Nymph (biology)
In biology, a nymph is the immature form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph's overall form already resembles that of the adult, except for a lack of wings (in winged species). In addition, while a nymph moults, it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars. This is the case, for example, in Orthoptera (crickets, grasshoppers and locusts), Hemiptera (cicadas, shield bugs, whiteflies, aphids, leafhoppers, froghoppers, treehoppers etc.), mayflies, termites, cockroaches, mantises, stoneflies and Odonata (dragonflies and damselflies). Nymphs of aquatic insects, as in the Odonata, Ephemeroptera, and Plecoptera, are also called naiads, an Ancient Greek name for mythological water nymphs. Usage of the term 'naiad' is no longer popular among entomologists, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
