Dysphania subrepleta is a brilliantly coloured moth of the genus Dysphania. They all look pretty similar and there’s not much about this particular species to be found. Tell you what though – we know that it lives on Koh Chang.

Dysphania is a genus of colourful moths in the family Geometridae. With a typical wingspan of 5–8.5 centimetres (2.0–3.3 in), they are relatively large compared to most members of this family. Most Dysphania are day-flying, but there are also nocturnal species. They are found in northeast Australia, Melanesia, and south, east and southeast Asia.

The Leopard Lacewing (Cethosia cyane) is a species of heliconiine butterfly found from India to southern China (southern Yunnan), and Indochina. Its range has expanded in the last few decades, and its arrival in the southern part of the Malay Peninsula, including Singapore, is relatively recent.

The Animal Pictured is a Female
Similar to the male in markings, but the tawny groundcolour replaced by pale greenish white, somewhat brownish on the upperside of fore wing, the extent of black on this wing larger. Underside with all the markings paler than in the male the red at the base of the wings replaced by brownish yellow on the fore, white on the hind wing. Antennae, head and thorax dusky brown; abdomen dusky above, white beneath.

Common Crow (Euploea core)

The common crow (Euploea core) is a common butterfly found in South Asia and Australia. In India it is also sometimes referred to as the common Indian crow, and in Australia as the Australian crow. It belongs to the crows and tigers subfamily Danainae (Danaini tribe).

E. core is a glossy black, medium-sized 85–95 millimetres (3.3–3.7 in) butterfly with rows of white spots on the margins of its wings. Euploea core is a slow, steady flier. Due to its unpalatability it is usually observed gliding through the air with a minimum of effort. As caterpillars, this species sequesters toxins from its foodplant which are passed on from larva to pupa to the adult. While feeding, it is a very bold butterfly, taking a long time at each bunch of flowers. It can also be found mud puddling with others of its species and often in mixed groups. The males of this species visit plants like Crotalaria, Heliotropium to replenish pheromone stocks which are used to attract a mate during courtship.

The common crow is the most common representative of its genus Euploea. Like the tigers (genus Danaus), the crows are inedible and thus mimicked by other Indian butterflies (see Batesian mimicry). In addition, the Indian species of the Euploea genus shows another kind of mimicry, Müllerian mimicry. Accordingly, this species has been studied in greater detail than other members of its genus in India.

Last Observed By: Michael Erik Maria Finder

The painted Jezebel, is a medium-sized butterfly of the family Pieridae, found in South Asia and Southeast Asia.

Instead of the usual uneducated stuff I put in here let’s just, for once, list the massive level of detail that Wikipedia gives on this species and marvel in gratitude at the level of devotion and expertise of true butterfly fanciers.

This species closely resembles Delias eucharis but can be distinguished as follows: Male upper forewing has the black margins to the veins more diffuse; the transverse postdiscal band diffuse, ill-defined, oblique, not parallel to termen in its lower portion but terminated at apex of vein 2; the apical portion of the wing beyond the fascia more or less so thickly shaded with black scales as to leave the white lanceolate (lance-shaped) spaces between the veins (so prominent in D. eucharis) ill defined and obscure. Hindwing white, the black venation and terminal narrow black border as well as the sub-terminal vermilion-red spots between the veins on the underside show through by transparency. Underside: forewing as in D. eucharis, but the black margins to the veins much broader and the postdiscal transverse fascia as on the upperside oblique but broader. Hindwing differs from that of D. eucharis in the much deeper chrome-yellow tint of the ground colour, the postdiscal black curved band that in D. eucharis separates the yellow from the subterminal vermilion-red spots entirely wanting, the red spots themselves pointed inwardly, not subcordate, they conspicuously increase in size posteriorly. Antennae, head, thorax and abdomen similar to those of D. eucharis. Female differs from the female of D. eucharis on the upperside by the very much darker shading, especially on the forewing, and by the postdiscal transverse band which is as in the D. eucharis oblique but broader. Hindwing also more darkly shaded, the postdiscal transverse curved black baud entirely absent. Underside as in the female but darker, the forewing especially more thickly shaded with black scaling, the preapical interspaces tinged with yellow. Antennae, thorax and abdomen similar to those in D. eucharis.
Delias hyparete metarete female, upperside

Subspecies D. h. metarete, Butler (Southern Myanmar; extending to Java and Sumatra) differs from D. h. hierta as follows: Male upperside has the ground colour a much purer white; apical half of forewing in contrast with the white on basal half densely shaded with black scales. Underside: the colours clearer and purer, the chrome yellow on the hindwing confined to the base and posterior half of the wing, the apical half of the cell and the anterior interspaces within the line of the vermilion-red spots pure white; the anterior two or three subterminal red spots margined interiorly with diffuse black scaling. Female differs less from the 2 of D. h. hierta, but on the underside of the hindwing the yellow colour is as restricted as it is in the male; the subterrninal red spots are of a richer vermilion than in D. h. hierta, and the anterior two or three as in the d have an interior narrow margin of diffuse black scales. Antennae, head, thorax and abdomen as in D. h. hierta, but the thorax and abdomen shaded slightly darker with a bluish-grey appearance.

Subspecies D. h. ethire, Doherty (Madras; Orissa; Lower Bengal) differs from typical D. h. hierta as follows: Male upperside very pure white. Forewing has the black margins to the veins very narrow, the oblique postdiscal band ill defined, scarcely any irroration of black scales on the apical half of the wing. Hindwing pure white, the colours of the underside seen through by transparency as in D. h. hierta. Underside differs from D. h. hierta principally in the brighter tint of the yellow on the hindwing, and in the more clearly defined, less diffuse black margins of the veins. Female differs less from female D. h. hierta than does the male from the corresponding sex of the same insect. Upperside has the interspaces beyond the postdiscal oblique band on forewing and the cell and basal halves of the interspaces beyond the cell on the hindwing distinctly tinged with yellow. Underside: all the markings more neatly and clearly defined than in D. h. hierta, the interspaces beyond the oblique postdiscal band on the forewing bright lemon-yellow. Antennae, head, thorax and abdomen in both sexes as in D. h. hierta.

The Common Pierrot is presumably named after the creepy and rather unpleasant Italian clowns of the same name. It’s black and white you see.

It actually has a really attractive pattern though with all kinds of leopard-like spots on a white background.

It is a South Asian native butterfly that is a member of the lycaenid family of butterflies.

The Tailed Judy is a small butterfly that is a member of the Punches and Judies (great naming again) family of butterflies.

The male and female have similar patterns but the male is slightly paler. They are mainly brown in colour with some nice white go-faster stripes and some of those sneaky eye-like patterns on their wings – presumably to deceive predators.

Giant Forest Scorpion

Giant Forest Scorpion (Heterometrus spinifer)

Observed By: Stuart Phillips

The giant forest scorpion is a formidably armed beast with its two huge pincers and a venomous sting on the tail.

But don’t be afraid (for once!). It actually has a relatively mild sting and isn’t considered to be a danger to humans. It’s venom is comparable to that of a wasp or a bee. Not fun but not life-threatening.

Giant forest scorpions grow up to 12 centimetres long and inhabit dark and damp habitats such as leaf litter and rotten trees. It is distributed through Malaysia, Thailand, Cambodia and Vietnam.

They feed on insects such as cockroaches, grasshoppers and locusts.

Observed: Koh Chang Reefs, December 2015

Observed By: Jonathan Milnes

Merten’s Sea Anemone is the largest of all the sea anemones – another Koh Chang species that’s the biggest of its kind. It has a diameter of over 1 metre and attaches itself to the sea bed with special wart-like protuberances called verrucae.

Like most anemone species it has symbiotic relationships with anemonefish – which protect the anemones from predation in return for the protective environment of the anemone’s stinging tentacles. This species hosts  plays host to around half of all the different species of anemone fish.

Arachnaphobes look away, click return, nothing to see here.
Everyone else celebrate the marvellous Thailand black tarantula. It is a species of old-world tarantula native to Thailand.
They are floor living jungle dwellers and reside in a burrow that is surrounded by special web filaments that, when triggered by prey, will bring the spider out to capture and feed.

There are actually several similar species of Haplopelma in Thailand/Burma/Cambodia/laso area and they are quite similar so this might be one of the sisters of Minax. The last recognised species Haplopelma Longipes was only identified in 2005, so you never know, this might be a new one.

Observed By: Perry Stevens

This common species of ladybird is found from India across to Australasia.

From a human perspective this little beetle is one of the good guys since it preys on many plant eating insects such as aphids and leafhoppers that cause damage to commercial crops.

It has a black head and a red/orange body with sort of Rorschach blotches where (if you’re European) you’d expect to see spots.
