Top 20 Most Common Insects in Nabua

Orthetrum serapia is a medium-sized dragonfly with a wingspan of 60-85mm. Its wings are clear except for a small dark spot at the base of the hindwing. The thorax is greenish to greyish yellow with black markings. The abdomen is black with pale yellow or pale green markings. Orthetrum serapia appears very similar to Orthetrum sabina and can be confused where the range of the two overlap in north-eastern Australia.

Neurothemis terminata is a species of dragonfly in family Libellulidae. Neurothemis terminata is a widespread and often common species which can occur in man-made habitats, from Peninsular Malaysia and Japan to the Lesser Sundas in Indonesia. Male N. terminata have red colour on its body and wings, while the female have yellowish colour. The adult has 8-11 cm body length.

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.

Ricania speculum can reach a length of about 8 mm, with a wingspan of about 1.5 cm. These planthoppers have dark brown wings with central wavy horizontal bands and irregular transparent patches of different sizes. The precostal area of the forewings shows dense transverse veinlets and the costal margin is distinctly convex near the base. In males the tip of the abdomen is pointed, while in females is rounded. The final instar nymphs are white with dark brown markings and waxy secretions on the abdomen.

Female black-and-white spiny spider are 6 - 9 mm wide and possess a hard, shiny abdomen armed with six black conical spines. The upper surface of the abdomen is white to yellowish with variable black or dark brown markings and sigilla. Males are much smaller at 3 - 4 mm and in place of spines have small bumps on their abdomens.

Male: upperside umber brown. Forewing with the costal margin narrowly fulvous (reddish brown) near apex, crossing towards the termen, forming an obscure preapical band joining a subterminal lunular band of the same colour. Hindwing uniform, with a subterminal band as in the forewing but not lunular, straight. Underside pale brown, with the following transverse pale lilac-white bands crossing both forewing and hindwing: basal, subbasal, discal, postdiscal, broad subterminal and terminal; the subbasal and discal of equal width, meeting above the tornal angle in V-shape, the space between the two bands with, on the forewing, two shorter similar bands crossing the cell, on the hindwing a single similar band from costa to median vein; subterminal band on hindwing bent upwards above tornal area and continued halfway up the dorsal margin, the broadly-produced tornus with a dark brown spot; finally a large ochraceous ocellus in interspace 2, and a smaller similar one in interspace 6. Antennae reddish; head, thorax and abdomen umber brown. Secondary sex-mark a glandular fold in membrane of wing shaded by tufts of long hair along vein 1 on upperside of hindwing, and preapically on the abdomen with tufts of stiff long hairs. Female: Upper and undersides as in the male but paler; on the upperside the fulvous along the costal margin widens into a preapical patch, and generally the bands on the underside show through and appear above as pale fulvous bands.Wingspan: 11 - 12 cm .Eggs: The freshly laid eggs are creamy white with a small black spot in the centre and a black circular ring. The eggs are laid in a row. At Thenmala, the observer saw two rows, the first having 15 eggs and the second 3 eggs. Prior to hatching, the colour of the egg changes to black. Larvae: The first instar larvae are cylindrical, measuring 0.6 - 0.8 mm in length. The second instar larvae are pale greenish yellow measuring 0.8 - 1.2 mm in length. The third instar larvae are morphologically very similar to the previous instar, but are longer ( 3 - 4 cm ) and stouter. The fourth instar larvae are stouter and longer measuring 4.5 - 5 cm . During the fifth instar, the larvae become more brownish than greyish and measure 7 - 8 cm in length. Larvae of the palm king are voracious feeders. Most of the time, they remain on the underside of the leaf, eating from the tip of the leaf working towards the base. With regard to coloration, the fifth instars show marked difference in their ground colour: some being more brownish and some more greyish. Pupa: The process of pupation takes about half a day and resulted in a greenish spindle-shaped pupa, well-camouflaged among the pointed leaves of the host plant. Initially, they are semi-transparent but later they become more opaque. The pupa has veins and lines similar to that of the leaves of the host plant, all veins ending at the pointed lower end of the pupa. The pupa becomes transparent on the eve of hatching, with the wings and head clearly visible.

Dardanus pedunculatus usually attain a maximum size of 10 centimetres (4 in). The carapace is mottled in tan and cream, while the eyestalks are white with red bands. The sexes are similar. The left claw is much larger than the right claw.

The larvae are black, with two rows of dorsal white spots. Head with a pair of branched spines; rest of the segments with a dorsal and a lateral row of blue branched spines on each side. The pupae are yellowish with numerous black spots; constricted in the middle; head produced into two points. Male's and female's underside yellowish brown, paling anteriorly to rich golden yellow on the forewing, shading anteriorly into dusky brown on the hindwing. Forewing: the apical half black, following a line from vein 12 opposite the discocellulars, passing through apex of cell, obliquely across middle of interspace 3 and curving down to tornus; a black spot near apex of cell coalescing with the inner margin of 1he black colour; a short, very oblique, broad golden-yellow band, broader in the female than in the male, from middle of costal margin to interspace 5; a spot beyond in line with it in interspace 4; two, sometimes three, minute, preapical white specks; the cilia fulvous (tawny), touched with white, anteriorly. Hindwing uniform; the costal margin broadly as noted above, a subterminal narrow band and narrower terminal line posteriorly, dusky black; a postdiscal black spot in interspaces 2 and 5 respectively; the cilia fulvous. The ground colour varies from reddish to dark greenish brown with irrorations (speckles) of greyish and black scales; apex of the forewing and the terminal margin posteriorly of the hindwing more or less lilacine; forewings and hindwings crossed by a dark narrow discal fascia, generally bordered on the inner side by a greyish line; this fascia bent inwards at right angles above vein 6 of the forewing and in most specimens, bordered internally by a diffuse pale patch and externally by an oblique whitish mark, beyond which is a subcostal white spot, followed by a transverse sinuous postdiscal series of obscure ocelli crossing both wings, each ocellus centred by a minute dot, white on the fore, black on the hindwing. In the male there are generally, but not invariably, a number of whitish spots on the basal areas of both wings. Antennae blackish brown, ochraceous at apex; head, thorax and abdomen dark fulvous brown; beneath, the palpi white, the thorax and abdomen pale brown. Wingspan is about 8 - 9 cm.

Its wingspan is about 84–104 mm. Head and thorax reddish chestnut in colour, where the third joint of palpi black. Abdomen crimson. Forewings reddish chestnut, slightly irrorated with dark scales. There are traces of a sinuous antemedial line with three specks on it. Reniform greyish, where the lower part more or less completely filled in with black. A curved postmedial series of white specks with an indistinct band beyond it angled at vein 6 and met by a dark streak from the apex. A marginal series of specks present. Hindwings crimson with black sub-marginal medial patch. Larva ophiusine-shaped with an apple-greenish body and finely lined longitudinally with purple-centered double white lines. The dorsolateral pair of conical tubercles are yellowish patched with red. The larvae feed on Careya, Barringtonia and Planchonia species.
