Trithemis aurora
crimson marsh glider
crimson marsh glider
Trithemis is a genus of dragonflies in the family Libellulidae. They are commonly known as dropwings. There are over 40 species, mainly from Africa; two are endemic to Madagascar, and five can be found in Asia.
They are found in a wide variety of habitats, some species being adapted to permanent streams in forests, and others being capable of breeding in temporary pools in deserts.
Trithemis aurora, the crimson marsh glider, is a species of dragonfly in the family Libellulidae, it is a common and widely distributed species found throughout the year across the Indian subcontinent and Southeast Asia.
The male of the species is distinctly different from the female, male has a reddish-brown face, with eyes that are crimson above and brown on the sides, thorax is red with a fine, purple pruinescence. The abdomen, the base of which is swollen, is crimson with a violet tinge. The wings are transparent with crimson venation and the base has a broad amber patch. The wing spots are a dark reddish-brown and the legs are black.
The female has an olivaceous or bright reddish-brown face with eyes that are purplish-brown above and grey below. The thorax is olivaceous with brown median and black lateral stripes and the abdomen is reddish-brown with median and lateral black markings. The black markings are confluent at the end of each segment and enclose a reddish-brown spot. The wings are transparent with brown tips. The venation is bright yellow to brown and basal amber markings are pale. The wing spots are a dark brown and the lags are dark grey with narrow yellow stripes.
It is commonly found in weedy tanks and ponds, marshes, channels, and slow flowing streams and rivers in the lowlands and mid-hills. It breeds in streams, rivers, canals, ponds and tanks.

The long-legged marsh glider or dancing dropwing (Trithemis pallidinervis) is a species of dragonfly found in Asia
The long-legged marsh glider is a medium-sized yellowish brown dragonfly with long legs. In males, the face is yellow or pale brown in front and iridescent purple above. The eyes are colored reddish brown above, brown on sides and bluish grey below. The thorax is olivaceous brown above with a dark brown triangle. On the sides, it is bright yellowish brown with three black stripes on each side. The legs are black, long, and spidery. The basal half of the femora of the first pair of legs are bright yellow. The wings are transparent with reddish venation. The forewings have amber basal markings. The wings have a golden sheen when viewed from certain angle. Wing spot is black with creamy white ends. The abdomen looks bright yellow in color with black median and lateral stripes. These stripes are confluent at the end of each abdominal segment to enclose a wedge shaped yellow spot. The male varies in colour from yellow (below) to chocolate brown when matured.
The females are similar to males but with a broad abdomen. The only way to distinguish the male from the female is the projection on segment two (secondary genital) and purple frons on the face.
This dragonfly is seen near marshes, weedy ponds and lakes where it breeds. It usually perches on tall aquatic weeds or bare ends of shrubs. The long legs are very clearly noticeable at this time. One of the most readily seen dragonflies due to its perching habit and up-winged posture, poised at the tip of swaying reeds.

Blue dasher
Brachydiplax chalybea is a species of dragonfly in the family Libellulidae. It is known by the common names yellow-patched lieutenant, rufous-backed marsh hawk, and blue dasher. It is native to much of eastern Asia, from India to Japan to Indonesia.
The male of the species is 33 to 35 millimeters long and has a hindwing 24 to 27 millimeters long. It is powder blue with light brown sides and a dark tip to the abdomen. Wings are hyaline, with tinted burnt-brown base, fading to amber. The female is brownish yellow in color with darker markings along the dorsal abdomen. Its wings lack the yellow tinge. This species can be easily distinguished from other species in this genus by its larger size, characteristic colour of the thorax, and bases of wings.
This species is found in many types of wet habitat, including brackish and disturbed waters. The males are seen more often, due to their territorial behavior. Females oviposit by "flicking" an egg mass out of the water into rocks and vegetation nearby.

Bradinopyga geminata
granite ghost
granite ghost
Bradinopyga geminata is a species of dragonfly in the family Libellulidae known commonly as the granite ghost. It is native to India, Sri Lanka and Thailand, where it is a common and widespread species.
It is a medium sized dragonfly with brown-capped grey eyes. Its thorax is cinereous, marbled and peppered with black in a very irregular manner. Wings are transparent with dual color pterostigma, black at centre and pure white at distal and proximal ends.
Abdomen is coloured very similarly to thorax; black marbled with yellow, but with a more definite plan. Segments 3 to 8 have pale basal annules interrupted on dorsum, and formed by two elongate parallel spots. There is a triangular apical sub-dorsal spot and a pale mid-dorsal spot. Anal appendages are creamy-white. Female is similar to the male.
Taking advantage of its cryptic coloration, it always rests flat on slab rock or cement-plastered walls, where it almost invisible. Adults occupy habitat near water bodies, such as pools, irrigation channels, wells, and containers with standing water. It breeds in rainy hollows in the rocks or in wells and small cemented tanks.
The species has been studied as a predator of the disease-carrying yellow fever mosquito (Aedes aegypti). The larvae of the dragonfly consume the larvae of the mosquito in the standing-water habitat types that both occupy.

Gynacantha subinterrupta
Dingy duskhawkers
Dingy duskhawkers
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 easily 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 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.
Gynacantha is a genus of dragonflies in the family
Aeshnidae. The Aeshnidae, also called aeshnids, hawkers, or darners, is a family of dragonflies.
The family includes the largest dragonflies found in North America and Europe and among the largest dragonflies on the planet.
Gynacantha is a dragonfly genus with 87 species distributed throughout the world, especially in the tropics and subtropics (Asahina 1993; Schorr & Paulson 2009).
Among them about 30 species are known from the Southeastern Asia.
Dragonflies of the genus are large in size, pale brown and green in color and are crepuscular by nature (Fraser 1936).
According to Fraser (1933), blues and greens developing very late in life; thus the majority of descriptions depict the insects as drab brown relieved only by darker shades, whilst the full adult insects are often very beautiful in their display of blended greens and blues.
The females have two prominent spines under the last abdominal segment. This gives the genus name(from Greek female and thorn) and the common name two-spined darners, they are also known as duskhawkers or dingy duskhawkers.
