Calopterygidae
Calopterygidae is a Family (biology), family of damselfly, damselflies, in the suborder Zygoptera. They are commonly known as the broad-winged damselflies, demoiselles, or jewelwings. These rather large damselflies have wingspans of 50–80 mm (compared to about 44 mm in the common bluetail damselfly, ''Ischnura elegans''), are often metallic-coloured, and can be differentiated from other damselflies by the broader connection between the wings and the body, as opposed to the abrupt narrowing seen in other damselfly families. The family contains some 150 species. The Calopterygidae are found on every continent except Antarctica. They live along rivers and streams.Córdoba-Aguilar, A. & Cordero-Rivera, A.

James George Needham
James George Needham (March 16, 1868 in Virginia, Illinois – July 24, 1957) was an American entomologist. After studying with John Henry Comstock at Cornell University (1896–1898) he taught biology at Lake Forest University (1898–1907). In 1908 returned to Cornell as assistant professor of limnology. When Comstock retired in 1914, Needham became head of the Department of Entomology at Cornell until his retirement in 1935. Needham published numerous scientific articles, educational papers, and textbooks but is best known for the Comstock–Needham system for describing insect wing venation. He was a Member of the Entomological Society of America, the American Association for the Advancement of Science and the Limnological Society of America.

Elizabeth Gault Fisher
Elizabeth Gault Fisher (April 29, 1909) was an American entomologist, bacteriologist, and bryologist. She collected thousands of examples of Maryland mosses, including the first examples of a number of species in Maryland. A moss, '' Desmatodon fisherae'', and an insect, '' Mycetophila fisherae'', were named for her. Early life Elizabeth Gault Fisher was born on April 29, 1909, in Baltimore, Maryland. She was the daughter of Anne (née Baylor) and Dr. William A. Fisher, health commissioner of Baltimore. She attended the Calvert School, St. Timothy's School, graduating in 1927, and Roland Park Country School, graduating in 1930. She studied at Cornell University beginning in 1930, and graduating with a Bachelor of Science in 1934, a master's degree and a Ph.D. in entomology in 1938. Her dissertation was ''A Comparative Study of the Male Terminalia of the Mycetophilidae of Nearctic America.'' Career In 1939, Fisher went to Philadelphia to research moss. Fisher became ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Damselfly
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies (which constitute the other odonatan suborder, Epiprocta) but are usually smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. Damselflies have existed since the Late Jurassic, and are found on every continent except Antarctica. All damselflies are predatory insects: both nymphs and adults actively hunt and eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acidic bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, but their dependence on fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Odonata Of South America
Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the '' Epiophlebia'' damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and wings folded together along body at rest. Adult odonates can land and perch, but rarely walk. All odonates have aquatic larvae called naiads or nymphs, and all of them, larvae and adults, are carnivorous and are almost entirely insectivorous, although at the larval stage they will eat anything that they can overpower, including small fish, tadpoles, and even adult newts. The adults are superb aerial hunters and their legs are specialised for catching prey in flight. Odonata in its narrow sense forms a subgroup of the broader Odonatoptera, which contains other dragonfly-like insects. T ...
