Superb Jewelwing
The superb jewelwing (''Calopteryx amata'') is a species of damselfly in the family Calopterygidae. It is native to North America, where it is distributed in eastern Canada and the northeastern United States as far south as Tennessee.NatureServe. 2015''Calopteryx amata''.NatureServe Explorer, Version 7.1.

Hermann August Hagen
Hermann August Hagen (30 May 1817 – 9 November 1893) was a German entomologist who specialised in Neuroptera and Odonata. He had established himself as one of Europe's preeminent entomologists by 1867 when he accepted a position at Harvard University to curate the Museum of Comparative Zoology. In 1870 he became the first entomologist in the United States to hold the formal title, Professor of Entomology. Biography Hagen was born 30 May 1817 in Königsberg, Prussia. He was the son of Anna (Linck) Hagen and Carl Heinrich Hagen. His father was a senior government counselor and a professor of political science at the University of Königsberg and his grandfather, Karl Gottfried Hagen, was a professor of chemistry at the same university.Henshaw (1894) Young Hagen graduated from a gymnasium in 1836 and began to study medicine at the University of Königsberg. His course of studies was greatly influenced by his zoology professor, Martin Heinrich Rathke and together they toured m ...

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] [Amazon] |
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. (2005)Evolution and ecology of Calopterygidae (Zygoptera: Odonata): status of knowledge and research perspectives.''Neotrop. Entomol'' 34(6), 861-879.

Ophiogomphus
''Ophiogomphus'', commonly known as snaketails, is a genus of dragonflies in the family Gomphidae. Most of the species in the genus ''Ophiogomphus'' have beautifully marked green club-shaped abdomens, which are more noticeable in the males. The genus contains the following species: *''Ophiogomphus acuminatus'' – acuminate snaketail *''Ophiogomphus anomalus'' – extra-striped snaketail *''Ophiogomphus arizonicus'' – Arizona snaketail *''Ophiogomphus aspersus'' – brook snaketail *''Ophiogomphus australis'' – southern snaketail *''Ophiogomphus bellicosus'' *''Ophiogomphus bison'' – bison snaketail *''Ophiogomphus carolus'' – riffle snaketail *''Ophiogomphus caudoforcipus'' *''Ophiogomphus cecilia'' – green snaketail, green gomphid *''Ophiogomphus cerastis'' *''Ophiogomphus colubrinus'' – boreal snaketail *''Ophiogomphus edmundo'' – Edmund's snaketail *''Ophiogomphus howei'' – pygmy snaketail *''Ophiogomphus incurvatus'' – Appalachian snaketail * ...

Odonata Of North 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 ...

Insects Of Canada
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.

Least Concern Biota Of The United States
The degrees of comparison of adjectives and adverbs are the various forms taken by adjectives and adverbs when used to compare two entities (comparative degree), three or more entities (superlative degree), or when not comparing entities (positive degree) in terms of a certain property or way of doing something. The usual degrees of comparison are the ''positive'', which denotes a certain property or a certain way of doing something without comparing (as with the English words ''big'' and ''fully''); the ''comparative degree'', which indicates ''greater'' degree (e.g. ''bigger'' and ''more fully'' omparative of superiorityor ''as big'' and ''as fully'' omparative of equalityor ''less big'' and ''less fully'' omparative of inferiority; and the ''superlative'', which indicates ''greatest'' degree (e.g. ''biggest'' and ''most fully'' uperlative of superiorityor ''least big'' and ''least fully'' uperlative of inferiority. Some languages have forms indicating a very large degree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Insects Described In 1889
Insects (from Latin ') are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum.

The insect nervous system consists of a brain and a ventral nerve cord. Most insects reproduce by laying eggs. Insects breathe air through a system of paired openings along their sides, connected to small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in vessels, and some circulates in an open hemocoel. Insect vision is mainly through their compound eyes, with additional small ocelli. Many insects can hear, using tympanal organs, which may be on the legs or other parts of the body. Th ...
