Lowland - Terai

Terai - National Parks Koshi Tapu, Parsa, Chitwan, and Bardia


Chitwan National Park was the first designated national park in Nepal, established in 1973. Before that, it was used for hunting by the Royal family of Nepal. It is most famous for tiger, elephant, rhino, and Garhial crocodiles. Tame elephants were used for jungle safaris but then in 2012, they were not allowed except in the buffer zones. Lodges were also removed from the park. Now the large tourist population stays on the north side of the Rapti River and visits the park by jeep or on foot. Dragonflies are found along with the banks of the Rapti River and on ponds and lakes within the park and a Ramsar site called Bees Hajar Taal or Twenty Thousand Lakes.

 Elephants and Rhinos are regular sights in the National Park.
Bardiya or Baria National Park was established in 1988. It is Nepal's largest National Park with 968 sq km of land, located in the far west region. It is well-known for tigers, rhinos, wild elephants, deer, and many types of birds.

Zygoptera

Neurobasis chinensis 
Linnaeus 1758
Elevation 80 - 1700m
A ubiquitous species in Nepal found from the Terai (80m) and up to mid-hills at Godavari 1500m. The main requirement is a well-vegetated, relatively clean, and flowing stream to sit on. The female is easily recognized by the cream-colored patches in the wings and the male with a flash of emerald green from the wings. 

Heliocypha biforata
(Selys 1859)
Elevation 80 - 1000m
Abdomen 19-20mm
At CNP there is a small stream and a pond inside the Chitwan buffer zone jungle. This species was found in the stream that was flowing through the jungle near the elephant center. It is the only sighting I have had of this species in Nepal, but it is common throughout Southeast Asia. The sighting was in April and there were a few females present but no photos were captured.
Libellago lineata
(Burmeister 1839)
Elevation 80-1000m
Abdomen length 14-16mm
Usually, found on flowing water, small to medium-sized rivers and streams. This one was on the Budhi Rapti River that feeds into the larger Rapti River which flows past Chitwan National Park and it was on the canal in the Bees Hajar Taal wetland, a Ramsar site. In Pokhara, it is found along the edges of Phewa Taal. The female is seen below resting on a stick with Trithemis festiva female.

A small attractive damselfly that I saw at Bees Hajar sitting on vegetation next to the canal. It is fairly common regionally. It is also located at Rupa Taal near Pokhara. It has two color forms for the female, one similar to a juvenile male and a red form.
Male
Female

Agriocnemis femina 
(Brauer 1868)
Elevation of level to 1000m
Abdomen length 16-17mm
Very similar to A. pygmaea in size and color, but usually has a pruinose thorax and darker abdomen to distinguish it from A. pygmaea. It is widely distributed throughout S and SE Asia and Australasia. It is found primarily in grasslands near ponds and lakes. This photo is from Parsa Reserve. 

Agriocnemis lacteola

A lovely milky white damselfly that is found in wetland areas. It was found in Bes Hajar Taal and in Haldi Bari forest wetland. The females are very attractive with a blue and black abdomen. About the same size as A. pygmaea but much easier to spot.

Agriocnemis pygmaea 
Rambur 1842
Elevation of sea level to 1370m
Abdomen 16-17mm
Hard to detect due to its minuscule size but it drifts between blades of grass next to ponds, streams, and wetland areas. Females have two color forms red and green that look similar to the male. Very common. Found at CNP, Bees Hajar, Parsa, Godavari, and many other locations around Nepal.

Aciagrion approximans approximans
Selys 1876
Elevation 80-800m
Abdomen Length 22-24mm
Another species from the Beeshajar Ramsar site and at Dipang Taal in Pokhara. Several wetland areas beside the road are accessible from the main track. The wetland was just beside a canal near one of the larger lakes - a very attractive purplish damselfly. Besides Nepal, it is found mostly in NE India.

Aciagrion pallidum
Selys, 1891
Elevation 800 to 1500m
Abdomen Length 31mm
With a ground-colored body, this one is hard to spot. The thorax has blue stripes and is very attractive up close. In Bees Hajar, it was next to a partially dried wetland. Also, it has been recorded at Lamjung, Bardia, and Syangja. It is usually found after the monsoon.

The Yellow Waxtail is a very common species in wetland areas throughout the region and even as far as Japan. The bright yellow body color is unmistakable. Females are similar in size but the color is more grass green.

Ischnura rubilio
(Brauer 1865)
sea-level to 1500m
Abdomen 16-20mm
The yellow and blue are a good contrast to the grassy areas where these small damselflies live. Still overlooked due to size it is found in ponds and wetlands. It is both common and widespread found all over Asia. In Nepal, it is seen in CHP, Godavari, Pokhara, Lamjung, and many other locations.

Ischnura forcipata
Morton 1907
Elevation 500 - 1800m
Abdomen 22-23mm
A pretty species with a bright green thorax, blue and black abdomen, and polychromatic females for a bit of confusion. Found mostly in wetlands and beside sluggish streams. It is common across the Asian region and across a range of elevations.

The female is an olive green color with fine lines on the surface of the abdomen and the thorax. 
Female

Onychargia atrocyana
Selys, 1865
Elevation 80-800mm
Abdomen length 23mm

Appearance is a black damselfly with small bluish-white colored rings at the abdominal segments. Younger males have yellowish stripes on the thorax that disappear with age, but stay visible on the females.

Family Platycnemididae
Copera vittata
Selys 1863
Elevation 200m
Long dark yellow-orange spidery legs without enlarged tibias and the longer caudal anal appendages at the end of the abdomen are ID indicators. There are several Copera sp that closely resemble each other and probably need a bit of work to separate them. C. vittata assamensis, C. vittata vittata, and C. marginipes are found in many regions across India and Southeast Asia. They are usually seen on slow or even slightly stagnate water and often in dark damp forested areas. Immature forms can be whitish in color and confusing at first glance.
This is Copera vitata from Manipur.

Copera marginipes
(Rambur 1842)
200-300m
The common name is Yellow Feather Legs. Closely related to C. vittata, this species has bright yellow legs with expanded tibias and very small caudal appendages. The habitat is very similar for both species. White forms exist for both teneral males and females.
One of many dragonfly predators

Family Aeschnidae

Gynacantha khasiaca
MacLachlan, 1896
Elevation 200m
Abdomen Length 48-49mm
Rare find! It was deep in the Chitwan jungle and only spotted as it was disturbed. This is listed as data deficient because so little is known about its habits and numbers. This one was about 10m from the Rapti River in a very thick jungle.

Family Gomphidae

Ictinogomphus rapax
Rambur 1842
Elevation 100- 1700m
Abdomen Length 40mm
It is a common sight on small ponds, lakes, and along rivers. This one was next to a very swampy pond in Bishajar Taal. While taking this photo I heard a grunt and looked up to see a large one-horned Rhino about 30 meters away. I was so focused on all the dragonflies that I failed to notice it...oops


Macrogomphus montanus 
Selys 1869
Elevation 80- 1000m
Abdomen Length 50mm
Newly emerged found clinging to the grass next to the Rapti River in the Chitwan National Park buffer zone (CNP). This is another listed as data deficient by IUCN, but it should be found in similar locations in India and Bangladesh. It is probably under-reported. This was photographed in early July and other records show specimens from June. Distribution is in NW India; NE India, Nepal, and Bangladesh.


Nepogomphus modestus
(Selys 1878)
Elevation 80-1000m

Elevation 60 - 800m
Abdomen length 39-41mm
The first name was Onychogomphus duaricus Fraser, 1924. This one was found in the Chitwan buffer zone near the National Park. A female was nearby but the photo is not very good. The habitat is near running water, usually small streams. They are usually found later in the season after the monsoon. Distribution is in NW & NE India, plus Bengal and Thailand.

Platygomphus dolabratus
(Selys 1854)
Elevation 200m
Abdomen Length 41mm
Found in the CNP buffer zone early morning resting on the grasses near the Rapti River, probably waiting for the weather to warm up. The female was found inside the jungle and some distance from the male closer to a small side river called the Budhi Rapti. Both were on the same day in early July. Distribution is in northern India, Nepal, and West Bengal.

Libellulidae

Acisoma panorpoides

Males and females are very similar. A wide-ranging species thought to migrate great distances. They are commonly called Globe Wanderers. They are found in abundant numbers just after heavy rain. They tend to breed quickly which aids their migratory habits.

Potamarcha congener
Rambur 1842
Elevation of sea level to 1500m
Abdomen 29-32mm
Yellow-tailed Ashy Skimmer is the common name. Here this specimen is older and the yellow color of the abdomen is less pronounced. The top of the eyes is a dark red color. The female is ochre-colored with expansions at the 8th abdominal segment.

Trithemis aurora
(Burmeister 1839)
Elevation 200-1800mm

A very common and beautiful species found along ponds, lakes, wetlands, and many other types of water bodies throughout Asia. The female shown below is yellow but similar to the male and sometimes has a bit of brown at the wingtips.


Trithemis festiva 
(Rambur 1842)
Elevation 180-2000m
A very widespread species and commonly found near running water. In Nepal, it is found in CNP and up to 1600m in the hills. The females are more difficult to spot as mating is rapid and females stay in the brush off to the sides of streams.

Trithemis palidinervis
(Kirby 1889)
Elevation 300 -2000mm
The Dancing Dropwing has long spidery legs and is often perched on top of grasses in or near wetlands, swamps, and next to ponds. Common throughout Asia.

Rhyothemis plutonia 
(Selys 1883)
Elevation 200-800m
Abdomen 20-22mm
Widely distributed across Southeast Asia to India. It is a wetland species that emerges in large batches along with R. variegata, R. triangluaris, and Neurothemis tulia. They swirl around in the air above the water for some time before settling on the grasses next to the wetland. I was not able to find a female but they might have been in the large mass of flutterers above my head.

Rhyothemis variegata
Linnaeus 1763
Elevation 180 - 1400m
Abdomen 23-25mm
The slow fluttery flight resembles a butterfly and the gold and black pattern is easy to see. The female, below, does not have color up to the wingtips. It is a very common wetland, swampy species that also lives near lakes and ponds. 

Rhyothemis triangularis
Kirby 1889
Elevation 600 - 900m
Abdomen 16-20mm
A very uncommon resident of canals, ponds, and small lakes in the reed beds it tends to sit a bit further out on water plants away from the shore. When seen in their preferred habitat there are usually good numbers of both males and females.

Tholymis tillarga
Fabricus 1789
Elevation 200 - 2000m
Abdomen 28-33mm
In the late evenings, T. tillarga cleans up on mosquitos along the edges of canals, ponds, and paddy fields.
