#5 - Green Dragontail Lamproptera meges, Zinken,1831


Lamproptera meges, the Green Dragontail, is a species of swallowtail butterfly (family Papilionidae) found in parts of South Asia and Southeast Asia.  The butterfly is found in northeastern India, in the states of Assam, Arunachal Pradesh, Manipur, and Nagaland. It is also found in Myanmar, Thailand, Laos, Vietnam, southern China (including Hainan), Cambodia, peninsular and eastern Malaysia, the Indonesian archipelago, Brunei, and the Philippines. In Indonesia, it is found on the islands of Sulawesi, Kalimantan, Nias, Bangka and Java. In 2006, it was reported from Zhangjiajie of Hunan Province. There are ten subspecies. A specimen from Java is the type species of the genus.

Taxonomic position

Class:     Insecta

Order:     Lepidoptera

Family:  Papilionidae

Genus:   Lamproptera Gray

Species: meges (Zinken, 1831)

Description:
The wingspan of an adult is about 28-38 mm. The butterfly have slightly broader HW then White Dragontail (L. curius), with greenish discal band on both wings, however, the green band usually faded away and turned to be white afterwards in dead specimens. The male of the species is without the scent fold (Ek-Amnuay 2006). Both the sexes are similar (Kehimkar 2008).

Status
The Green Dragontail is not known to be threatened in most of its range but is considered vulnerable in IUCN and in need of protection in peninsular Malaysia. (Collins & Collins 1985)


Habits
Among the smallest of swallowtails in India, the Green Dragontail is usually found singly along open sunlit patches, almost always near streams and water courses. It may also be seen in small groups, usually twos or threes. It flies in an altitude range of 100 to 1,520 metres (330 to 4,990 ft). It flies from April to October. Having much smaller wing size to body length ratio, the butterflies have a whirring flight, rapidly beat their wings and dart back and forth in a manner reminiscent of dragonflies, their long tails acting as rudders. Male dragontails suck up a lot of water from which the dissolved minerals are filtered and the water squirted from the anus. While feeding they vibrate their wings rapidly but pause from time to time. Occasionally, they rest on leaves of bushes with wings outspread and stationary.

Life cycle
The eggs are pale green, spherical, smooth, and almost transparent and resemble the eggs of other swallowtails. The caterpillar is dark green in colour and is spotted with black. The chrysalis is attached to the upper surface of a leaf by the cremaster.

Food plants
Illigera burmanica King (Family Hernandiaceae). In the Philippines, the butterfly has also been recorded from Zanthoxylum species (Rutaceae).

Sightings in Manipur
The Green Dragontail is usually found singly along open sunlit patches, almost always near streams and water courses. It may also be seen in small groups, usually twos or threes. In the past few years, the butterfly has been observed very frequently in the lower altitudes of valley and hills of Manipur. The butterfly was observed from Leimatak (Churachandpur district); Kongbamaru (Imphal East district); Leimaram (Imphal West district) and Kamjong (Ukhrul district) during the month of June, September, October and November. So, the species not rare but uncommon in Manipur.

They prefers forested hilly regions. Flies in the vicinity of water, frequently settles on roads and damp patches. Attracted to overripe fruits and tree sap. On the wing from March to December and seen in the Himalaya between 1000 and 3000 m  and in the south Indian Hills between 1000 and 1200 m. Males are territorial.

#2 - Lemon Pansy Junonia lemonias Linnaeus, 1758

Lemon Pansy Junonia lemonias Linnaeus, 1758

Junonia lemonias, the lemon pansy, is a common nymphalid butterfly found in South Asia. It is found in gardens, fallow land, and open wooded areas.

Description
It is brown with numerous eye-spots as well as black and lemon-yellow spots and lines on the upperside of the wings. The underside is a dull brown, with a number of wavy lines and spots in varying shades of brown and black. There is also an eyespot on the lower side of the forewing. The wet and dry-season forms differ considerably in coloration and even shape. In the wet-season form the markings are distinct and vivid and the wing shape is a little more rounded. In the dry-season form the markings are obscure and pale especially on the underside and the wing margin is more angular and jagged. This helps it camouflage in the dried leaf-litter. The lemon pansy is a very active butterfly and can be seen basking with its wings open facing the sun. It sits very low to the ground and can be approached easily. It feeds with its wings half open. It is a fairly strong flier and flies close to the ground with rapid wing beats and often returns to settle back in the same spots.

Description

Male upperside: somewhat more than half the forewing from base velvety black, apical half dull fuliginous; cell-area with or without two short transverse orange bars; a blue patch above, the tornus; the outer margin of the basal black area obliquely zigzag in a line from the middle of costa to apex of vein 2, including a large discal, generally obscure ocellus, which, however, in some specimens is prominently ringed with orange-yellow. Beyond this a broad while irregularly oblique discal band followed by a short oblique preapical bar frm costa; a small black orange-ringed ocellus beneath the bar, a subterminal continuous line of white spots in the interspaces and a terminal jet-black slender line; cilia alternately dusky black and white. Hindwing blue shaded with velvety black towards base; a postdiscal black white-centred orange and black-ringed ocellus in interspace 2, a round minutely white-centred velvety black spot (sometimes entirely absent) in interspace 5; the termen narrowly white, traversed by an inner and an outer subterminal and a terminal black line; cilia white.

Hindwing irrorated with dusky scales and transversely crossed by subbasal and discal slender zigzag brown lines and a postdiscal dark shade, on which are placed the two ocelli as on the upperside; sub terminal and terminal faint brown lines, and a brownish short streak tipped black at the tornal angle below the lower ocellus.
