Orange Bluet
The orange bluet (''Enallagma signatum'') is a species of damselfly in the family Coenagrionidae. Identification This species of bluet stands out from many other bluets because of its orange color. On male orange bluets, the thorax is orange with a thick, black stipe along the back and black shoulder stripes. His abdomen is mostly black with some orange rings, orange below, and orange near the tip. His large eyes are orange on a black head; small orange postocular spots are connected across the back of the head by an orange bar. On female orange bluets, the thorax is similar looking to the male thorax only the color is dull yellow instead of orange. Her abdomen is mostly black above and dull yellow below. Her large eyes are yellow-brown with small yellow postocular spots connected by a thin, yellow bar. The female can also be one of three forms. The first remains blue throughout life, one becomes green and the third becomes orange. Habitat This bluet is often found near str ...

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 ...

New Brunswick
New Brunswick is a Provinces and Territories of Canada, province of Canada, bordering Quebec to the north, Nova Scotia to the east, the Gulf of Saint Lawrence to the northeast, the Bay of Fundy to the southeast, and the U.S. state of Maine to the west. It is part of Eastern Canada and is one of the three Maritime Canada, Maritime provinces and one of the four Atlantic Canada, Atlantic provinces.

Insects Of The United States
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.

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. The ...

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 ...

Cercus
Cerci (: cercus) are paired appendages usually on the rear-most segments of many arthropods, including insects and symphylans. Many forms of cerci serve as sensory organs, but some serve as pinching weapons or as organs of copulation. In many insects, they simply may be functionless vestigial structures. In basal arthropods, such as silverfish, the cerci originate from the eleventh abdominal segment. As segment eleven is reduced or absent in the majority of arthropods, in such cases, the cerci emerge from the tenth abdominal segment. It is not clear that other structures so named are homologous. In the Symphyla they are associated with spinnerets. Morphology and functions Most cerci are segmented and jointed, or filiform (threadlike), but some take very different forms. Some Diplura, in particular ''Japyx'' species, have large, stout forcipate (pincer-like) cerci that they use in capturing their prey. The Dermaptera, or earwigs, are well known for the forcipate cerci that most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Protoneuridae
Protoneuridae was formerly considered a family (biology), family of damselfly, damselflies. Recent taxonomic revisions have classified the species previously placed in Protoneuridae into two existing families - Coenagrionidae and Platycnemididae, both in the superfamily Coenagrionoidea. Along with Pseudostigmatidae, New World Protoneuridae are now sunk in Coenagrionidae and Old World Protoneuridae in Platycnemididae. Genera The family Protoneuridae contained more than twenty genera. The following genera are now in the family Coenagrionidae: *''Amazoneura'' Machado, 2004 *''Drepanoneura'' von Ellenrieder & Garrison, 2008 *''Epipleoneura'' Williamson, 1915 *''Epipotoneura'' Williamson, 1915 *''Forcepsioneura'' Lencioni, 1999 *''Idioneura'' Selys, 1860 *''Lamproneura'' De Marmels, 2003 *''Microneura'' Hagen ''in'' Selys, 1886 *''Neoneura'' Selys, 1860 *''Peristicta'' Hagen ''in'' Selys, 1860 *''Phasmoneura'' Williamson, 1916 *''Proneura'' Selys, 1889 *''Protoneura'' Selys ''in'' ...
