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 mati ...

Caspar Stoll
Caspar Stoll (Landgraviate of Hesse-Kassel, Hesse-Kassel, probably between 1725 and 1730 – Amsterdam, December 1791) was a naturalist and Entomology, 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 entomology, insect groups. Stoll's 1787 publication on Phasmatodea, 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 Landgraviate of Hesse-Kassel, 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: se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolichodial
Dolichodial is a natural chemical compound with two aldehyde groups, which belongs to the group of iridoids. 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 Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phasmatodea
The Phasmatodea (also known as Phasmida or Phasmatoptera) are an Order (biology), order of insects whose members are variously known as stick insects, stick bugs, walkingsticks, stick animals, or bug sticks. They are also occasionally referred to as Devil's darning needles, although this name is shared by both Dragonfly, dragonflies and Tipuloidea, 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 Apparitional experience, apparition or Ghost, 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 antipredator adaptation, lines of defense in the form of startle displays, spines or toxic secretions.

Journal Of Natural Products
The ''Journal of Natural Products'' is a monthly peer-reviewed scientific journal covering all aspects of research on the chemistry and/or biochemistry of naturally occurring compounds. 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. The American Society of Pharmacognosy began to co-publish the journal with the American Chemical Society in 1996. In 2008, the journal was hijacked by a low-quality open access journal using the same title. , this counterfeit journal was still active. Abstracting and indexing The journal is abstracted ...

Leaf Beetle
The beetle family Chrysomelidae, commonly known as leaf beetles, includes over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making it 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 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. Members of former chrysomelid subfamilies ( Orsodacnidae and Megalopodidae) are also difficult to differentiate from true chrysomelids. Adult and larval leaf beetles feed o ...

Biosynthetic Pathway
In biochemistry, a metabolic pathway is a linked series of chemical reactions occurring within a cell. The reactants, products, and intermediates of an enzymatic reaction are known as metabolites, which are modified by a sequence of chemical reactions catalyzed by enzymes. In most cases of a metabolic pathway, the product of one enzyme acts as the substrate for the next. However, side products are considered waste and removed from the cell. Different metabolic pathways function in the position within a eukaryotic cell and the significance of the pathway in the given compartment of the cell. For instance, the electron transport chain and oxidative phosphorylation all take place in the mitochondrial membrane. In contrast, glycolysis, pentose phosphate pathway, and fatty acid biosynthesis all occur in the cytosol of a cell. There are two types of metabolic pathways that are characterized by their ability to either synthesize molecules with the utilization of energy ( anabolic pa ...

Nymph (biology)
In biology, a nymph (from Ancient Greek wikt:νύμφα, νύμφα ''nūmphē'' meaning "bride") is the juvenile (organism), juvenile form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (biology), 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) and the emergence of genitalia. In addition, while a nymph ecdysis, moults, it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars. Taxa with nymph stages Many species of Arthropod, arthropods have nymph stages. This includes the insect orders such as Orthoptera (cricket (insect), crickets, grasshoppers and locusts), Hemiptera (cicadas, shield bugs, Whitefly, whiteflies, aphids, leafhoppers, froghoppers, treehoppers), mayfly, mayflies, termites, cockroaches, mantises, ...
