Thomas Say
Thomas Say (June 27, 1787 – October 10, 1834) was an American entomologist, conchologist, and herpetologist. His studies of insects and shells, numerous contributions to scientific journals, and scientific expeditions to Florida, Georgia, the Rocky Mountains, Mexico, and elsewhere made him an internationally known naturalist. Say has been called the father of American descriptive entomology and American conchology. He served as librarian for the Academy of Natural Sciences of Philadelphia, curator at the American Philosophical Society (elected in 1817), and professor of natural history at the University of Pennsylvania. Early life and education Born in Philadelphia into a prominent Quaker family, Thomas Say was the great-grandson of John Bartram, and the great-nephew of William Bartram. His father, Dr. Benjamin Say, was brother-in-law to another Bartram son, Moses Bartram. The Say family had a house, "The Cliffs" at Gray's Ferry, adjoining the Bartram family farms in King ...

Dragonfly
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of true dragonfly are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterized by a pair of large, multifaceted compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural colouration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder ( Zygoptera) and are similar in body plan though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, along or ...

Macromiidae
The insect family Macromiidae contains the dragonfly species known as cruisers or skimmers. They tend to fly over bodies of water (and roads) straight down the middle. They are similar to Aeshnidae in size, but the eyes are green and just barely meet at the top of the head. Macromiidae, or Macromiinae, has been traditionally considered as a subfamily of Corduliidae (). It contains four genera and 125 species worldwide. Females of this family lack an ovipositor at the end of the abdomen and lay their eggs by dipping the abdomen in the water as they fly over. Ovipositing is usually done without a male. Early Stages The Naiads hatch after two weeks and are born with three gills for respiration (Lung 2001). Naiad In Greek mythology, the naiads (; grc-gre, ναϊάδες, naïádes) are a type of female spirit, or nymph, presiding over fountains, wells, springs, streams, brooks and other bodies of fresh water. They are distinct from river gods, who ...s are found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
D Transversa
D, or d, is the fourth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''dee'' (pronounced ), plural ''dees''. History The Semitic letter Dāleth may have developed from the logogram for a fish or a door. There are many different Egyptian hieroglyphs that might have inspired this. In Semitic, Ancient Greek and Latin, the letter represented ; in the Etruscan alphabet the letter was archaic, but still retained (see letter B). The equivalent Greek letter is Delta, Δ. Architecture The minuscule (lower-case) form of 'd' consists of a lower-story left bowl and a stem ascender. It most likely developed by gradual variations on the majuscule (capital) form 'D', and today now composed as a stem with a full lobe to the right. In handwriting, it was common to start the arc to the left of the vertical stroke, resulting in a serif at the top of the arc. This serif ...

Corduliidae
The Corduliidae, also knowns as the emeralds, emerald dragonflies or green-eyed skimmers, is a family of dragonflies. These dragonflies are usually black or dark brown with areas of metallic green or yellow, and most of them have large, emerald-green eyes. The larvae are black, hairy-looking, and usually semiaquatic. This family include species called "baskettails", "emeralds", "sundragons", "shadowdragons", and "boghaunters". They are not uncommon and are found nearly worldwide, but some individual species are quite rare. Hine's emerald dragonfly (''Somatochlora hineana''), for example, is an endangered species in the United States. Selected genera Some genera included in this family are: * '' Aeschnosoma'' * '' Antipodochlora'' – Dusk dragonfly * '' Cordulia'' – American emeralds * '' Corduliochlora'' * '' Cordulisantosia'' * '' Dorocordulia'' – little emeralds * '' Epitheca'' – baskettails * '' Guadalca'' * '' Helocordulia'' – sundragons * ''Hemicordulia ...
