Top 20 Most Common Insects in Thailand

It is brown with numerous eyespots 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.

Diplacodes trivialis is small dragonfly with bluish eyes and greenish-yellow or olivaceous thorax and abdomen with black marks. In very old adults, the whole thorax and abdomen become uniform pruinosed blue. Clear wings, without apical or basal markings, and the creamy white anal appendages and deep pruinescence in adults help to distinguish this species from others in its genus.

Male. "The upperside of the male is chalky-white, sometimes with a more or less broad and clearly defined basal sulphur-yellow area on both fore and hind wings; this sulphur-yellow colour is at times diffused over the whole surface of the wings, though generally it becomes paler towards the terminal margins. For the fore wing, the whole, or sometimes only the apical half, of the costa narrowly black, this color widened out irregularly at the apex; termen widely black at the apex, the colour narrowed posteriorly. This border in some specimens almost reaches the tornus, in others terminates above vein 4; occasionally it is continued posteriorly by a series of block dots at the apices of the veins. The Hind wing generally are uniform, unmarked, and some specimens bear minute black dots at the apices of the veins. "On the underside the groundcolour is very variable, with white with a slight to strong ochraceous tinge, greenish white or sulphur-yellow. The fore wing is typically without markings, in some specimens with a patch of sulphur-yellow on either side of base of median nervure, in the very yellow examples the tornal area is often widely greenish white, in others (Catopsilia catilla, Cramer) it bears a spot variable in size on the discocellulars. This spot has a pearly centre and an outer reddish line. Many specimens have an irregular angulated narrow discal reddish line (the colour varies in intensity) that runs from the costa obliquely outwards to vein 7, and then obliquely inwards to vein 2, though this line is often absent in specimens that bear the discocellular spot; apex and termen sometimes very narrowly reddish. The hind wing is typically uniform, without markings." Female. "On the female upperside the ground-color varies as in the male, but sometimes it is chalky white at the bases of the wings, with the terminal margins more or less broadly sulphur-yellow. Fore wings always with a round, occasionally quadrate, black discocellular spot variable in size; in some specimens the costa is black only towards the apex of the wing, in others broadly black throughout and opposite the apex of cell so widened out as to touch the discocellular spot. In lightly marked specimens in addition to the discocellular spot, there is only an irregular terminal black band dentate inwardly and widest at the apex of the wing; in others there is in addition a more or less diffuse highly curved macular postdiscal band that extends from the costa obliquely outwards down to vein 7, where it often touches the terminal black band, and thence is continued downward and slightly inclined inwards to interspace 1, getting gradually paler and fainter posteriorly. Hind wing are a series of terminal inter-spacial black spots that vary in size, and in the dark forms coalesce into a terminal black band."

The species is on the IUCN Red List as not endangered, year of assessment 2009. The slender bank dragonfly occurs from Southeastern Europe and North Africa to Japan and Australia

The giant golden orb weaver (Nephila pilipes) is known for spinning a golden web. Despite that being neat, that isn't the weirdest part about them. Females are known to favor gigantism, causing males to be much smaller than average females. Males are known to have mating plugs which attempt to prevent other males from mating, but the size difference can make this tricky.

The Senegal Pechlibelle (Ischnura senegalensis) is a dragonfly from the family of the slender dragonflies (Coenagrionidae).

The male has a reddish-brown face, with eyes that are crimson above and brown on the sides. The 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. 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.

Cethosia cyane, the leopard lacewing, 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 species is on the IUCN Red List as not endangered, year of assessment 2007.

The striped albatross (Appias libythea) is a combination of whites and greys and yellows that allow this butterfly to resemble many different types of flowers. They are part of a family that exhibits mud-puddling, where they stomp about wet puddles in order to get salt.
