19-11-2016 THA YET MIO, MYANMAR - STINK BUG (Eysarcoris montivagus)
Eysarcoris is a genus of shield bugs belonging to the family Pentatomidae, subfamily Pentatominae, and typical of the tribe Eysarcorini.
Stink bugs of this genus are relatively small (<6 mm in length) and obovate in shape. There is a dense covering of punctures on much of the body. The head and the ventral surface of the thorax are covered with club-shaped hairs.
Eysarcoris belongs to a group of stink bugs (also including Sepontia, Spermatodes and Stagonomus) which have a broad scutellum and an auriculate/spine-like process anterior to the scent gland opening, and do not have a median sulcus in the thoracic sterna.
19-11-2016 THA YET MIO, MYANMAR - PYGMY GRASSHOPPER (Subfamily Tetriginae)
Tetriginae is a large subfamily of groundhoppers or pygmy grasshoppers. Members of Tetriginae occur on every continent except Antarctica.
Most categories of organisms have "common names" in spoken languages. These names are usually recognizable, easy to pronounce, and stable over time, but many organisms have several different names in different places, even in the same language, which can make it difficult to communicate about these organisms without confusion. Scientists address this problem by using a single "scientific name" for each category of organism that conforms to the rules of biological nomenclature, but these names tend to be based on Latin, a language nobody speaks, so they are not as memorable as common names for many people. Scientific names can also reflect an organism's taxonomic placement, so they can change when scientists develop more accurate theories about the evolutionary relationships between different organisms, again reducing their usefulness in communication, even among people who know scientific names.
The old adage sums it up: "Common names change from place to place, and scientific names change from time to time."
19-11-2016 THA YET MIO, MYANMAR - GREEN MARSH HAWK DRAGONFLY (Orthetrum sabina)
Orthetrum sabina, the slender skimmer or green marsh hawk, is a species of dragonfly in the family Libellulidae. It is widespread, being found from south-eastern Europe and North Africa to Japan and south to Australia and Micronesia.
It is a medium-sized dragonfly with a wingspan of 60-85mm. Adults are greyish to greenish yellow with black and pale markings and green eyes. Its abdomen is greenish-yellow, marked with black. It is very similar to Orthetrum serapia in appearance, with both species appearing in northern Australia. Pale markings on segment four of the abdomen do not extend into the posterior section when viewed from above on Orthetrum sabina. Females are similar to males in shape, colour and size; differing only in sexual characteristics. This dragonfly perches motionless on shrubs and dry twigs for long periods. It preys voraciously on smaller butterflies and dragonflies.
19-11-2016 THA YET MIO, MYANMAR - SCARLET SKIMMER DRAGONFLY (MALE) (Crocothemis servilia)
The scarlet skimmer or ruddy marsh skimmer, Crocothemis servilia, is a species of dragonfly of the family Libellulidae, native to east and southeast Asia and introduced to Jamaica, Florida, and Hawaii.
It is a medium sized blood-red dragonfly with a thin black line along the mid-dorsal abdomen. Its eyes are blood-red above, purple laterally. Thorax is bright ferruginous, often blood-red on dorsum. Abdomen is blood-red, with a narrow black mid-dorsal carina. Anal appendages are blood-red. Female is similar to the male; but with olivaceous-brown thorax and abdomen. The black mid-dorsal carina is rather broad.
It breeds in ponds, ditches, marshes, open swamps and rice fields.
The Skimmer Dragonfly, known for its mesmerizing aerial displays and vibrant colors, is a fascinating insect species found across various continents. With its elongated body, large multifaceted eyes, and intricate wings, the Skimmer Dragonfly is a true marvel of nature. These agile creatures inhabit a diverse range of habitats, from freshwater lakes and ponds to slow-moving streams and marshes. Throughout their life cycle, Skimmer Dragonflies undergo remarkable transformations, starting as aquatic nymphs before emerging as sleek-winged adults capable of swift flight. They play a vital role in ecosystem balance by preying on pesky insects like mosquitoes, thus serving as natural pest controllers.
A "Darners Dragonfly" perches on a stem, displaying its spread wings.
Despite facing threats from habitat loss and environmental degradation, Skimmer Dragonflies continue to captivate human interest, serving as subjects of study and admiration for enthusiasts and scientists alike. Through their beauty, behavior, and ecological importance, Skimmer Dragonflies offer a window into the intricate workings of the natural world, reminding us of the wonders that abound in the world of insects.
19-11-2016 THA YET MIO, MYANMAR - BLACK DRONGO (Dicrurus macrocercus)
The black drongo is found predominantly in open country and usually perches and hunts close to the ground. They are mostly aerial predators of insects but also glean from the ground or off vegetation. They are found as summer visitors to northeastern Afghanistan and northern Pakistan but are residents from the Indus Valley until Bangladesh and into India and Sri Lanka. Some populations show seasonal movements that are poorly understood while populations in Korea are known to be migratory. The black drongo can be found in savanna, fields, and urban habitats.
Black drongos were introduced just before the Second World War from Taiwan to the island of Rota to help in the control of insects. It is believed that they dispersed over the sea to the island of Guam in the 1950s. By 1967, they were the fourth most commonly seen birds in roadside counts on Guam and are today the most abundant bird there. Predation by and competition from black drongos have been suggested as factors in the decline of endemic bird species such as the Rota bridled white-eye and the Guam flycatcher.

16-11-2016 TANT KYI TAUNG - HOUSE SPARROW (MALE) (Passer domesticus)
The house sparrow (Passer domesticus) is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of 16 cm (6.3 in) and a mass of 24–39.5 g (0.85–1.39 oz). Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus Passer, the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird.
The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, polar regions, and hot, dry deserts far away from human development. For sustenance, the house sparrow routinely feeds at home and public bird feeding stations, but naturally feeds on the seeds of grains, flowering plants and weeds. However, it is an opportunistic, omnivorous eater, and commonly catches insects, their larvae, caterpillars, invertebrates and many other natural foods.
16-11-2016 TANT KYI TAUNG - HOUSE CROW (Corvus splendens)
The House crow (Corvus splendens) is a common bird of the crow family that is of Asian origin but now found in many parts of the world, where they arrived assisted by shipping.
The House crow is relatively small and slim-bodied, with long legs and plumage that is mostly black or blackish-slate. ‘Shining raven’ is the meaning of its scientific name, referring to its glossy, jet-black feathers around the face, chin, crown, and throat. Males and females are similar in appearance. Juveniles have duller plumage which does not feature the adults’ glossy black sheen.
The House crow is widely distributed throughout southern Asia, from southern Iran through Pakistan, India, and Bangladesh and into south-western China, southern Tibet, and central Thailand, as well as the Maldives. It has been introduced to places in Africa, Europe, the Middle East, and several islands, such as Mauritius. A small population is established around St. Petersburg, Florida. It is typically a lowland species, found in both tropical and subtropical areas. Some, however, have been seen in Himalayan military bases. This bird is strongly associated with humans, living in cities, towns, and villages. Interestingly, no populations are known to live in areas where there are no people.
5-11-2016 SHANGHAI, CHINA - BLACK CROWNED NIGHT HERON (Nycticorax nycticorax)
The Black-crowned night heron (Nycticorax nycticorax) is a medium-sized heron found throughout a large part of the world. These birds have a stocky appearance as if hunched over, the head tucked down into the shoulders, and they are usually seen with this posture. They are most active at dusk or at night when their ghostly forms fly from their daytime roosts to the wetlands where they forage.
Adult birds have a black crown and back with the remainder of the body white or grey, red eyes, and short yellow legs. They have pale gray wings and white under parts. Two or three long white plumes, erected in greeting and courtship displays, extend from the back of the head. The sexes are similar in appearance although the males are slightly larger. Black-crowned night herons do not fit the typical body form of the heron family.
They are relatively stocky with shorter bills, legs, and necks than their more familiar cousins, the egrets and "day" herons. Their resting posture is normally somewhat hunched but when hunting they extend their necks and look more like other wading birds. Immature birds have dull grey-brown plumage on their heads, wings, and backs, with numerous pale spots. Their underparts are paler and streaked with brown. The young birds have orange eyes and duller yellowish-green legs.
Black-crowned night herons breed on every continent apart from Antarctica and Australasia. In the Americas, it is from Washington to Quebec, through coastal Mexico, and in Central America and the Caribbean. In winter they can be found as far north as the New England states and Oregon. The Old World subspecies occur from Japan to Europe, Africa, and India. This heron lives in a wide range of habitats, from swamps, rivers, and lakes to salt marshes, lagoons, and mudflats. Aquatic and marginal vegetation like mangroves, reed beds, bamboo, and other trees are necessary for nesting and roosting.
6-11-2016 SHANGHAI, CHINA - RED EARED SLIDER TERRAPIN (Trachemys scripta ssp. elegans)
The red-eared slider or red-eared terrapin (Trachemys scripta elegans) is a subspecies of the pond slider (Trachemys scripta), a semiaquatic turtle belonging to the family Emydidae. It is the most popular pet turtle in the United States, is also popular as a pet across the rest of the world, and is the most invasive turtle. It is the most commonly traded turtle in the world.
The red-eared slider is native from the Midwestern United States to northern Mexico, but has become established in other places because of pet releases, and has become invasive in many areas where it outcompetes native species. The red-eared slider is included in the list of the world's 100 most invasive species.
Invasive red-eared sliders cause negative impacts in the ecosystems they are introduced to because they have certain advantages over the native populations, such as a lower age at maturity, higher fecundity rates, and larger body size, which gives them a competitive advantage at basking and nesting sites, as well as when exploiting food resources. They also transmit diseases and displace the other turtle species with which they compete for food and breeding space.
Owing to their popularity as pets, red-eared sliders have been released or escaped into the wild in many parts of the world. This turtle is considered one of the world's worst invasive species. Feral populations are now found in Bermuda, Canada, Australia, Europe, Great Britain, South Africa, the Caribbean Islands, Israel, Bahrain, the Mariana Islands, Guam, Russia, and south- and far-east Asia. Within Great Britain, red-eared sliders have a wide distribution throughout England, Scotland, and Wales.
In Australia, it is illegal for members of the public to import, keep, trade, or release red-eared sliders, as they are regarded as an invasive species – see below. Their import has also been banned by the European Union as well as specific EU member countries. In 2015, Japan announced it was planning to ban the import of red-eared sliders, but it would probably not take effect until 2020.
Red-eared sliders do not hibernate, but actually brumate; while they become less active, they do occasionally rise to the surface for food or air. Brumation can occur to varying degrees. In the wild, red-eared sliders brumate over the winter at the bottoms of ponds or shallow lakes. They generally become inactive in October, when temperatures fall below 10 °C (50 °F). During this time, the turtles enter a state of sopor, during which they do not eat or defecate, they remain nearly motionless, and the frequency of their breathing falls. Individuals usually brumate under water, but they have also been found under banks and rocks, and in hollow stumps. In warmer winter climates, they can become active and come to the surface for basking. When the temperature begins to drop again, however, they quickly return to a brumation state. Sliders generally come up for food in early March to as late as the end of April.
6-11-2016 SHANGHAI, CHINA - MALLARD (MALE) (Anas platyrhynchos)
The mallard (/ˈmælɑːrd, ˈmælərd/) or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. It has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. Males have green heads, while the females (hens or ducks) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent purple or blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is 50–65 cm (20–26 in) long, of which the body makes up around two-thirds the length.
The wingspan is 81–98 cm (32–39 in) and the bill is 4.4 to 6.1 cm (1.7 to 2.4 in) long. It is often slightly heavier than most other dabbling ducks, weighing 0.7–1.6 kg (1.5–3.5 lb). Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes.
The female lays 8 to 13 creamy white to greenish-buff spotless eggs, on alternate days. Incubation takes 27 to 28 days and fledging takes 50 to 60 days. The ducklings are precocial and fully capable of swimming as soon as they hatch.
The mallard is widely distributed across the Northern and Southern Hemispheres; in North America its range extends from southern and central Alaska to Mexico, the Hawaiian Islands, across the Palearctic, from Iceland and southern Greenland and parts of Morocco (North Africa) in the west, Scandinavia and Britain to the north, and to Siberia, Japan, and South Korea. Also in the east, it ranges to south-eastern and south-western Australia and New Zealand in the Southern hemisphere It is strongly migratory in the northern parts of its breeding range, and winters farther south.
The mallard inhabits a wide range of habitats and climates, from the Arctic tundra to subtropical regions. It is found in both fresh- and salt-water wetlands, including parks, small ponds, rivers, lakes and estuaries, as well as shallow inlets and open sea within sight of the coastline. Water depths of less than 0.9 metres (3.0 ft) are preferred, with birds avoiding areas more than a few metres deep. They are attracted to bodies of water with aquatic vegetation.
6-11-2016 SHANGHAI, CHINA - SWAN GOOSE (Anser cygnoides var. domesticus)
The swan goose was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Anas cygnoides. It is now one of 11 species placed in the genus Anser that was introduced by the French zoologist Mathurin Jacques Brisson in 1760.[6] The specific epithet combines the Latin cygnus meaning "swan" with Ancient Greek -oidēs meaning "resembling". The species is monotypic: no subspecies are recognised.
The swan goose is large and long-necked for its genus, wild birds being 81–94 cm (32–37 in) long (the longest Anser goose) and weighing 2.8–3.5 kg (6.2–7.7 lb) or more (the second-heaviest Anser, after the greylag goose, A. anser). The sexes are similar, although the male is larger, with a proportionally longer bill and neck; in fact the largest females are barely as large as the smallest males. Typical measurements of the wing are 45–46 cm (18–18 in) in males, 37.5–44 cm (14.8–17.3 in) in females; the bill is about 8.7–9.8 cm (3.4–3.9 in) long in males and 7.5–8.5 cm (3.0–3.3 in) in females. The tarsus of males measures around 8.1 cm (3.2 in). The wingspan of adult geese is 160–185 cm (63–73 in).
The upperparts are greyish-brown, with thin light fringes to the larger feathers and a maroon hindneck and cap (reaching just below the eye). The remiges are blackish, as are the entire underwing and the white-tipped rectrices, while the upper- and undertail coverts are white. A thin white stripe surrounds the bill base. Apart from darker streaks on the belly and flanks, the underside is pale buff, being especially light on the lower head and foreneck which are sharply delimited against the maroon. In flight, the wings appear dark, with no conspicuous pattern. Uniquely among its genus, the long, heavy bill is completely black; the legs and feet, on the other hand, are orange as in most of its relatives. The eyes' irides are maroon. Juveniles are duller than adult birds, and lack the white bill base and dark streaks on the underside.
The voice is a loud, drawn-out and ascending honking aang. As a warning call, a similar but more barking honk is given two or three times in short succession.
The swan goose was uplisted from Near Threatened to Vulnerable on the IUCN Red List in 1992 and further to Endangered in 2000, as its population is declining due to habitat loss and excessive hunting and (particularly on the Sanjiang Plain in China) egg collecting. But new research has shown it to be not as rare as it was believed, and consequently, it was downlisted to Vulnerable status again in 2008. Still, less than 500 pairs might remain in Russia, while in Mongolia numbers are unknown, though about 1,000 were seen at Ögii Lake in 1977. Favorite wintering locations in China are Lake Dongting, Lake Poyang, the Yancheng Coastal Wetlands and other locations around the lower Yangtze River, where some 60,000 individuals may be found each year – though this may be almost the entire world population. Until the 1950s, the species wintered in small numbers (up to about 100 birds annually) in Japan, but habitat destruction has driven them away.

16-11-2016 SALAY, MYANMAR - COMMON MYNA (Acridotheres tristis)
The Common myna (Acridotheres tristis) is a tropical bird with a strong territorial instinct, which has adapted extremely well to urban environments. The range of the Common myna is increasing at such a rapid rate that in 2000 the IUCN Species Survival Commission declared it one of the world's most invasive species and one of only three birds listed among "100 of the World's Worst Invasive Species" that pose a threat to biodiversity, agriculture, and human interests.
Common mynas can be recognized by their brown body, black hooded head, and the bare yellow patch behind the eye. Their bill and legs are bright yellow. There is a white patch on the outer primaries and the wing lining on the underside is white. The male and female look similar and are usually seen in pairs.
Common mynas are native to Asia with their home range spanning from Iran, Pakistan, India, Nepal, Bhutan, Bangladesh, and Sri Lanka; as well as Afghanistan, Uzbekistan, Tajikistan, Turkmenistan, Myanmar, to Malaysia, Singapore, peninsular Thailand, Indo-China, Japan (both mainland Japan and the Ryukyu Islands) and China. These birds are typically found in a wide range of habitats with access to water; they inhabit open woodland, mangroves, grasslands, farmlands, orchards, and urban areas.
16-11-2016 SALAY, MYANMAR - PIED BUSH CHAT (FEMALE) (Saxicola caprata)
The pied bush chat (Saxicola caprata ) is a small passerine bird found ranging from West Asia and Central Asia to the Indian subcontinent and Southeast Asia. About sixteen subspecies are recognized through its wide range with many island forms. It is a familiar bird of countryside and open scrub or grassland where it is found perched at the top of short thorn trees or other shrubs, looking out for insect prey. They pick up insects mainly from the ground, and were, like other chats, placed in the thrush family Turdidae, but are now considered as Old World flycatchers.
They nest in cavities in stone walls or in holes in an embankment, lining the nest with grass and animal hair. The males are black with white shoulder and vent patches whose extent varies among populations. Females are predominantly brownish while juveniles are speckled.
Among the Toda people in the Nilgiris, the pied bushchat or kāŗpiłc, is a bird of omen and the origin of its white wing patches is described in a story of a dairy priest Piu.f who in the ritual of churning milk forgot to remove the churning stick before fetching water from a stream. The bird attempted to obstruct him by blocking his path but he disregarded it and flicked off butter from his hands. The white spots remained but Piu.f met his death. The Kotas of the Nilgiris have an origin story to explain the sexual dimorphism of the pied bushchat but they consider the "karyvaky" bird to be one that foretells good omen. The Kalam people of Papua New Guinea consider the birds as messengers.
16-11-2016 SALAY, MYANMAR - PLAIN TIGER BUTTERFLY (Danaus chrysippus)
Danaus chrysippus, also known as the plain tiger, African queen, or African monarch, is a medium-sized butterfly widespread in Asia, Australia and Africa. It belongs to the Danainae subfamily of the brush-footed butterfly family Nymphalidae. Danainae primarily consume plants in the genus Asclepias, more commonly called milkweed. Milkweed contains toxic compounds, cardenolides, which are often consumed and stored by many butterflies. Because of their emetic properties, the plain tiger is unpalatable to most predators. As a result, its colouration is widely mimicked by other species of butterflies. The plain tiger inhabits a wide variety of habitats, although it is less likely to thrive in jungle-like conditions and is most often found in drier, wide-open areas.
D. chrysippus encompasses three main subspecies: D. c. alcippus, D. c. chrysippus, and D. c. orientis. These subspecies are found concentrated in specific regions within the larger range of the entire species.
The plain tiger is believed to be one of the first butterflies depicted in art. A 3,500-year-old ancient Egyptian fresco in Luxor features the oldest known illustration of this species.
18-11-2016 MINHLA, MYANMAR - BUSH BROWN BUTTERFLY (Genus Mycalesis)
Mycalesis perseus, the dingy bushbrown or common bushbrown, is a species of satyrine butterfly found in south Asia and southeast Asia.
Mycalesis, the bushbrowns, are a genus of brush-footed butterflies. They are common in the warm regions from Central Asia to Australia, and have a high diversity in South Asia and the Wallacea.
They are notably polymorphic, with wet- and dry-season forms differing in many species, especially as regards size and number of underwing eyespots.
Mycalesis superficially resemble the species Orsotriaena medus, but can readily be identified by the number of spots.
