Enallagma Signatum
The orange bluet (''Enallagma signatum'') is a species of damselfly in the family (biology), family Coenagrionidae. Identification This species of Enallagma, 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 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Insects Of The United States
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Inse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Odonata Of North America
Odonata is an order of flying insects that includes the dragonflies and damselflies. Members of the group first appeared during the Triassic, though members of their total group, Odonatoptera, first appeared in Late Carboniferous. The two common groups are distinguished with dragonflies, placed in the suborder Epiprocta, usually being larger, with eyes together and wings up or out at rest, while damselflies, suborder Zygoptera, are usually smaller with eyes placed apart and wings along body at rest. All Odonata have aquatic larvae called naiads (nymphs), and all of them, larvae and adults, are carnivorous. The adults can land, but rarely walk. Their legs are specialised for catching prey. They are almost entirely insectivorous. Etymology and terminology Fabricius coined the term ''Odonata'' in 1793 from the Ancient Greek ( Ionic form of ) 'tooth'. One hypothesis is that it was because their maxillae are notably toothed. Most insects also have toothed mandibles. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cercus
Cerci (singular cercus) are paired appendages 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 mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protoneuridae
The Protoneuridae are a family of damselflies. Most species are commonly known as threadtails, while others are commonly known as bambootails. Characteristics These are usually small-sized damselflies and their wings are narrow and mostly transparent, with simple venation. The males tend to be colourful and many have a red, orange, yellow or blue thorax and a black abdomen. Others have a black thorax and brightly coloured abdomen and others are entirely dark. Their usual habitats are the verges of rivers and streams and the margins of large lakes.
