Tetrathemis Platyptera
''Tetrathemis platyptera'', the pigmy skimmer, is a species of dragonfly in the family Libellulidae. It is widespread in many Asian countries and locally common over much of its range. Description and habitat It is a small dragonfly with yellow face and bluish green eyes. Its thorax and abdomen are yellow with broad black marks. Its wings are transparent, with fore-wings faintly and hind-wings broadly tinted with yellow at the bases. Females are similar to males. It breeds in vegetated ponds and wells. The female stabs her eggs onto dry twigs hanging over water. The eggs hatch out in rains and the naiad (insect), naiads fall directly into the water below.

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 ...

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] |
Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Naiad (insect)
In biology, a nymph is the immature form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (biology), metamorphosis (hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph's overall form already resembles that of the adult, except for a lack of wings (in winged species). In addition, while a nymph ecdysis, moults, it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars. This is the case, for example, in Orthoptera (cricket (insect), crickets, grasshoppers and locusts), Hemiptera (cicadas, shield bugs, Whitefly, whiteflies, aphids, leafhoppers, froghoppers, treehoppers etc.), mayfly, mayflies, termites, cockroaches, mantises, stonefly, stoneflies and Odonata (Dragonfly#Life cycle, dragonflies and damselfly, damselflies). Nymphs of aquatic insects, as in the Odonata, Ephemeroptera, and Plecoptera, are also called naiads, an Ancient Gree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Odonates Of Sri Lanka
Sri Lanka is a tropical island situated close to the southern tip of India. The invertebrate fauna is as large as it is common to other regions of the world. There are approximately 2 million known species of arthropods, and this number continues to grow. Thus, it is difficult to determine the exact number of Odonata species within particular regions. The following is a list of the dragonflies and damselflies of Sri Lanka. Dragonflies & Damselflies Phylum: Arthropoda Class: Insecta Order: Odonata. Dragonflies are predators. The larvae inhabit water and adults fly near aquatic places. They are diverse in color and shape. There are major 2 types of odonates in the world; they are dragonflies and damselflies. The eyes are closer together in dragonflies, and their wings are held broadly opened from the body. They are robust in nature. In contrast, damselflies are delicately built small odonates, with well separated compound eyes. During rest, they do not expand their wings; the win ...
