Sympetrum Frequens
The Autumn darter is a species of dragonfly endemic to Japan. It lives near grasslands and can grow up to 40 mm in length.''ふしぎがわかる しぜん図鑑 こんちゅう'', page 36. Froebel-Kan CO., LTD., 1999 After emerging, these dragonflies migrate to high mountains where they feed until descending to breeding pools (often temporary or artificial, including rice fields) at lower levels.

Edmond De Sélys Longchamps
Baron Michel Edmond de Selys Longchamps (25 May 1813 – 11 December 1900) was a Belgian Liberal Party politician and scientist. Selys Longchamps has been regarded as the founding figure of odonatology, the study of the dragonflies and damselflies. His wealth and influence enabled him to amass one of the finest collections of neuropteroid insects and to describe many species from around the world. His collection is housed in the Royal Belgian Institute of Natural Sciences. Biography Selys was a wealthy aristocrat born in Paris to Michel Laurent de Selys Longchamps and Marie-Denise Gandolphe. He was educated at home by private tutors and never attended school or university. Nevertheless, he became known as the world's leading authority on Odonata as well as an expert on Neuroptera and European Orthoptera. He was also a leading ornithologist. A Liberal Party representative in the Belgian Parliament, he became Councillor for Waremme in 1846, entered the Belgian Senate in 1855, a ...

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 ...

Grassland
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessment of Global Ecosystems, 2000) * "A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Akatombo
(also transliterated as ''Akatombo'', ''Aka Tombo'', ''Aka Tonbo'', or ''Aka Tomba'') is a famous doyo, Japanese children's song (''dōyō'') composed by Kōsaku Yamada in 1927, with lyrics from a 1921 poem by Rofū Miki. It is a nostalgic depiction of a Sympetrum frequens, Japanese red dragonfly seen at sunset by an infant being carried on an older sister's shoulder. Text The poem is written in the voice of someone recalling his infancy and being carried on the back of his sister (or nursemaid; the Japanese lyrics are ambiguous). The speaker now longs for this mother figure, who married at the age of 15, moved far away, and no longer sends news back to the speaker's village. Symbolist poet Rofū Miki (1889–1964), who wrote the poem in 1921, had a similar background. His mother had been married at the age of 15. His parents divorced when Miki was five years old, and his mother moved away, never to return. He was thereafter raised by his paternal grandfather. When he was 12 ...

Libellulidae
The skimmers or perchers and their relatives form the Libellulidae, the largest dragonfly family in the world. It is sometimes considered to contain the Corduliidae as the subfamily Corduliinae and the Macromiidae as the subfamily Macromiinae. Even if these are excluded (as Silsby does), there remains a family of over 1000 species. With nearly worldwide distribution, these are almost certainly the most often seen of all dragonflies. The genus ''Libellula'' is mostly New World, but also has one of the few endangered odonates from Japan: ''Libellula angelina''. Many of the members of this genus are brightly colored or have banded wings. The related genus ''Plathemis'' includes the whitetails. The genus ''Celithemis'' contains several brightly marked species in the southern United States. Members of the genus ''Sympetrum'' are called darters (or meadowhawks in North America) and are found throughout most of the world, except Australia. Several Southern Hemisphere species in the gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
