Euphydryas Editha Taylori
''Euphydryas editha taylori'', the Whulge checkerspot or Taylor's checkerspot, is a butterfly native to an area of the northwestern United States and Vancouver Island. Description Taylor's checkerspot is the darkest subspecies of the genus ''Euphydryas''. It is a subspecies of Edith's checkerspot. This butterfly has a wingspan of less than . It gets its name from the checkered color pattern on its wings that consist of black, orange and white coloring. Taylor's checkerspot once ranged from the Willamette Valley in Oregon to Vancouver Island in British Columbia. Chemical ecology Taylor's checkerspot larvae rely on complex multitrophic interactions for survival. The larvae feed upon certain plant species in the native ''Castilleja'' and exotic ''Plantago'' genera that produce defensive compounds called iridoid glycosides. Over time, the Taylor's checkerspot has developed a tolerance for these compounds, such that the larvae are able to consume the foliage of these plants and sequ ...

William Henry Edwards
William Henry Edwards (March 15, 1822 – April 2, 1909) was an American businessman and entomologist. He was an industrial pioneer in the coalfields of West Virginia, opening some of the earliest mines in the southern part of the state. He was also a prominent naturalist specializing in the study of butterflies. He wrote ''The Butterflies of North America'', a three-volume treatise that is highly regarded for its scholarship and the quality of its illustrations. Biography Edwards was born in Hunter, New York, a village that had been founded by his family just five years earlier and originally called Edwardsville. The son of William W. Edwards and Helen Ann (Mann) Edwards, he came from a prominent and successful American family. His father was a businessman involved in banking, insurance and European imports. His grandfather was Colonel William Edwards, founder of the family tannery business and inventor of several devices used in the manufacture of leather goods. His great-great- ...

Glycoside
In chemistry, a glycoside is a molecule in which a sugar is bound to another functional group via a glycosidic bond. Glycosides play numerous important roles in living organisms. Many plants store chemicals in the form of inactive glycosides. These can be activated by enzyme hydrolysis, which causes the sugar part to be broken off, making the chemical available for use. Many such plant glycosides are used as medications. Several species of ''Heliconius'' butterfly are capable of incorporating these plant compounds as a form of chemical defense against predators. In animals and humans, poisons are often bound to sugar molecules as part of their elimination from the body. In formal terms, a glycoside is any molecule in which a sugar group is bonded through its anomeric carbon to another group via a glycosidic bond. Glycosides can be linked by an O- (an ''O-glycoside''), N- (a ''glycosylamine''), S-(a ''thioglycoside''), or C- (a '' C-glycoside'') glycosidic bond. According to th ...

Butterflies Described In 1888
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, and after its wings have expanded and dried, ...

Jeffrey Glassberg
Jeffrey Glassberg is an American biologist and author. Following a distinguished academic career he pioneered and patented work in DNA Fingerprinting. Later he founded the North American Butterfly Association (NABA) and is the leading proponent of moving interest in butterflies from hobbyist collecting and nets to butterflying with binoculars and cameras. He has written a number of field guides as well as numerous articles. Life Early life Jeffrey Glassberg was born in Brooklyn, New York, on November 27, 1947, where his family lived until 1952 when they moved to Long Island, New York. His father established his own company making automobile seat covers and his mother worked there as well. Glassberg's early years were devoted to nature; bird-watching, chasing butterflies, and, with his younger brother, to chemistry experimentation. Moving from the buildings of New York City to a place of forests and meadows on Long Island where his parents allowed him to roam stimulated h ...

Plantago Lanceolata
''Plantago lanceolata'' is a species of flowering plant in the plantain family Plantaginaceae. It is known by the common names ribwort plantain, narrowleaf plantain, English plantain, ribleaf, lamb's tongue, and buckhorn. It is a common weed on cultivated or disturbed land. Description The plant is a rosette-forming perennial herb, with leafless, silky, hairy flower stems (). The basal leaves are lanceolate spreading or erect, scarcely toothed with 3-5 strong parallel veins narrowed to a short petiole. The flower stalk is deeply furrowed, ending in an ovoid inflorescence of many small flowers each with a pointed bract. Each inflorescence can produce up to two hundred seeds. Flowers are ( calyx green, corolla brownish), 4 bent back lobes with brown midribs and long white stamens. It is native to temperate Eurasia, widespread throughout the British Isles, but scarce on the most acidic soils ( pH < 4.5). It is present and widespread in the Americas and Australia as an

Microscope
A microscope () is a laboratory instrument used to examine objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using a microscope. Microscopic means being invisible to the eye unless aided by a microscope. There are many types of microscopes, and they may be grouped in different ways. One way is to describe the method an instrument uses to interact with a sample and produce images, either by sending a beam of light or electrons through a sample in its optical path, by detecting photon emissions from a sample, or by scanning across and a short distance from the surface of a sample using a probe. The most common microscope (and the first to be invented) is the optical microscope, which uses lenses to refract visible light that passed through a thinly sectioned sample to produce an observable image. Other major types of microscopes are the fluorescence microscope, electron microscope (both the transmi ...

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...
