Built between 1175 and 1490, Wells Cathedral has been described as "the most poetic of the English Cathedrals". Much of the structure is in the Early English style and is greatly enriched by the deeply sculptural nature of the mouldings and the vitality of the carved capitals in a foliate style known as "stiff leaf". The eastern end has retained much original glass, which is rare in England. The exterior has a splendid Early English façade and a large central tower.

The Phasmatodea (sometimes called Plasmodia) are an order of insects, whose members are variously known as stick insects (in Europe), walking sticks or stick-bugs (in the United States of America), phasmids, ghost insects and leaf insects (generally the family Phylliidae). The ordinal name is derived from the Greek "phasma" meaning an apparition or phantom, and refers to the resemblance of many species to sticks or leaves. Their natural camouflage can make them extremely difficult to spot. A few species (for example those in the genus Anisomorpha) are capable of secreting a substance from glands on the metathorax that can cause an intense burning irritation of the eyes (and in some cases temporary blindness) and mouth of potential predators on contact.

Grasshoppers are herbivorous insects of the suborder Ceasefire in the order Orthoptera. To distinguish them from bush crickets or katydids, they are sometimes referred to as short-horned grasshoppers. Species that change color and behavior at high population densities are called locusts. Recent estimates (Kevan 1982; Günther, 1980, 1992; Otte 1994-1995; subsequent literature) indicate some 2,400 valid Caeliferan genera and about 11,000 valid species described to date. Many undescribed species exist, especially in tropical wet forests.

Orgyia leucostigma, the White-marked tussock moth, is a moth in the family Lymantriidae. The caterpillar is very common especially in late summer in eastern North America, as far west as Texas, Colorado, and Alberta. There are two or more generations a year in eastern North America (Wagner 2005). They overwinter in the egg stage. Eggs are laid in a single mass over the cocoon of the female, and covered in a froth (Wagner 2005). Up to 300 eggs are laid at a time. he larvae are brightly coloured, with tufts of hair-like setae. The head is bright red, the body has yellow or white stripes, with a black stripe along the middle of the back. There are bright red defensive glands on the hind end of the back. Four white toothbrush-like tufts stand out from the back, and there is a grey-brown hair pencil at the hind end. Touching the hairs will set off an allergic reaction in many humans (Wagner 2005). Young larvae skeletonize the surface of the leaf, while older larvae eat everything except the larger veins (Rose and Lindquist, 1982). They grow to about 35 mm.

An illustration of white clover (left) and red clover (right). Clover (Trifolium), or trefoil, is a genus of about 300 species of plants in the pea family Fabaceae. The genus has a cosmopolitan distribution; the highest diversity is found in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants. The leaves are trifoliate (rarely 5- or 7-foliate), with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx

Coca is a plant in the family Erythroxylaceae, native to north-western South America. The plant plays a significant role in traditional Andean culture. Coca leaves contain cocaine alkaloids, a basis for the drug cocaine, which is a powerful stimulant. Coca should not be confused with the similarly named South American cocoa bean from which chocolate is made. The plant resembles a blackthorn bush, and grows to a height of 2–3 m (7–10 ft). The branches are straight, and the leaves, which have a green tint, are thin, opaque, oval, and taper at the extremities. A marked characteristic of the leaf is an areolated portion bounded by two longitudinal curved lines, one line on each side of the midrib, and more conspicuous on the under face of the leaf. The flowers are small, and disposed in little clusters on short stalks; the corolla is composed of five yellowish-white petals, the anthers are heart-shaped, and the pistil consists of three carpels united to form a three-chambered ovary. The flowers mature into red berries.

An illustration of an anamirta cocculus leaf. Anamirta cocculus is an Southeast Asian and Indian climbing plant. Its fruit, Cocculus indicus, is the source of picrotoxin, a poisonous alkaloid with stimulant properties. The plant is large-stemmed (up to 10cm in diameter); the bark is "corky gray" with white wood. The "small, yellowish-white, sweet-scented" flowers vary between 6 to 10 centimeters across; the fruit produced is a drupe, "about 1 cm in diameter when dry".

An illustration of a portion of a date palm leaf. The Date Palm (Phoenix dactylifera) is a palm in the genus Phoenix, extensively cultivated for its edible fruit. Due to its long history of cultivation for fruit, its exact native distribution is unknown, but probably originated somewhere in the desert oases of northern Africa, and perhaps also southwest Asia. It is a medium-sized tree, 15–25 m tall, often clumped with several trunks from a single root system, but often growing singly as well. The leaves are pinnate, 3–5 m long, with spines on the petiole and about 150 leaflets; the leaflets are 30 cm long and 2 cm broad. The full span of the crown ranges from 6–10 m.

An illustration of an earthworm. The basic body plan of an earthworm is a tube, the digestive system, within a tube, the muscular outer body. The body is annular, formed of segments that are most specialized in the anterior. Earthworms have a simple circulatory system. They have two main blood vessels that extend through the length of their body: a ventral blood vessel which leads the blood to the posterior end, and a dorsal blood vessel which leads to the anterior end. Most earthworms are decomposers feeding on undecayed leaf and other plant matter, others are more geophagous.

Crocus (plural: crocus, crocuses) is a genus of perennial flowering plants, native to a large area from coastal and subalpine areas of central and southern Europe (including the islands of the Aegean), North Africa and the Middle East, across Central Asia to western China. The genus Crocus is placed botanically in the iris family (Iridaceae). The plants grow from corms and are mainly hardy perennials, and are found in a wide range of habitats, including woodland, scrub and meadows. There are about eighty species of crocus (of which approximately 30 are cultivated). Their cup-shaped, solitary, salverform flowers taper off into a narrow tube. Their color varies enormously, although lilac, mauve, yellow and white are predominant. The grass-like, ensiform leaf shows generally a white central stripe along the leaf axis. The leaf margin is entire. All crocuses typically have three stamens. The spice saffron is obtained from the stigmas of Crocus sativus, an autumn/fall-blooming species.

The finial is an architectural device, typically carved in stone and employed to decoratively emphasize the apex of a gable, or any of various distinctive ornaments at the top, end, or corner of a building or structure. Smaller finials can be used as a decorative ornament on the ends of curtain rods or applied to chairs and furniture. These are frequently seen on top of bed posts or clocks. Decorative finials are also commonly used to fasten lampshades, and as an ornamental element at the end of the handles of souvenir spoons. Finials can also be decorative members at the ends of curtain rods. An architectural finial can also function as a lightning rod, and was once believed to act as a deterrent to witches on broomsticks attempting to land on one's roof.

An illustration of a fossil of a toothed fern. Ferns are vascular plants differing from the more primitive lycophytes by having true leaves (megaphylls), and they differ from seed plants (gymnosperms and angiosperms) in their mode of reproduction — lacking flowers and seeds. Like all other vascular plants, they have a life cycle referred to as alternation of generations, characterized by a diploid sporophytic and a haploid gametophytic phase.

Dill (Anethum graveolens) is a short-lived perennial herb. It is the sole species of the genus Anethum, though classified by some botanists in a related genus as Peucedanum graveolens (L.) C.B.Clarke. It grows to 40–60 cm (16–24 in) 1 inch, with slender stems and alternate, finely divided, softly delicate leaves 10–20 cm (3.9–7.9 in) long. The ultimate leaf divisions are 1–2 mm (0.039–0.079 in) broad, slightly broader than the similar leaves of fennel, which are threadlike, less than 1 mm (0.039 in) broad, but harder in texture. The flowers are white to yellow, in small umbels 2–9 cm (0.79–3.5 in) diameter. The seeds are 4–5 mm (0.16–0.20 in) long and 1 mm (0.039 in) thick, and straight to slightly curved with a longitudinally ridged surface.
