Top 14 Most Common Insects in Siquijor

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.

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.

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.

The scientific name Rhyothemis phyllis was first validly published in 1776 by Sulzer.

Upperside is white,base of wings are very slightly powdered with minute black scales.The costa of forewing is speckled obscurely with black; apex black, the inner margin of this inwardly angulate; a very large somewhat pear-shaped post-discal spot also black. Hindwing is white,in most specimens an obscure, extremely slender, terminal black line. Underside is white; costal margin and apex of forewing broadly, and the whole surface of the hindwing irrorated (speckled) with transverse, very slender, greenish strigae and minute dots; these on the hindwing have a tendency to form sub-basal, medial and discal obliquely transverse obscure bands; the postdiscal of forewing is black,spot as on the upperside; terminal margins of both forewings and hindwings with minute black, short, transverse slender lines at the apices of the veins, that have a tendency to coalesce and form a terminal continuous line as on the upperside. Antennae dark brown spotted with white, head slightly brownish, thorax and abdomen white. Female is similar as male, the black markings on the upperside of the forewing on the whole slightly broader, but not invariably so. Wingspan is 2.5 - 5 cm. Larva is green with a pale glaucous tinge about the bases of the legs and slightly hairy. Pupa sometimes green, but more often of a delicate pink shade.

The impatiens hawk moth can be considered a pest among commercial and residential gardeners. Both the moth and caterpillar feed on several flowering plants, including fuchsias and the Australian native violet. Adult females lay their eggs on the plant’s foliage, ensuring the hatching larvae have a ready food source.

Oxyopes macilentus, sometimes known as the lean lynx spider, is a species of lynx spiders from East Asia, South Asia, Southeast Asia, and northern Australia. They are active predators, hunting invertebrates (including other spiders) among vegetation. They are especially common in grassy areas and rice fields. Their bodies are characteristically long and thin, about four times as long as it is wide. Their body color ranges from pale white to yellow, orange, or green; with a pattern of black, orange, and white longitudinal lines. Females have a maximum body length of 10 mm (0.39 in), while males grow to 9 mm (0.35 in). The species was first described in 1878 by the German arachnologist Ludwig Carl Christian Koch. The specific name is from Latin macilentus ("lean" or "thin"), in reference to the spider's body. It is classified under the genus Oxyopes.

This butterfly is dark gray or black with two rows of circular white dots along the margins of its wings and elongated white patches closer to the body. The elongated white patches appear to radiate from the thorax.

Corymica pryeri is a species of moth of the family Geometridae first described by Arthur Gardiner Butler in 1878. It is found in Japan, Taiwan, the north-eastern Himalayas, Sumatra, Borneo, New Guinea and possibly Queensland, Australia. The wingspan is 25–30 mm. The larvae feed on Lindera, Neolitsea, Machilus, Meratia and Persea species. The larvae are slender and bright green with a blackish central stripe and blackish markings. Pupation takes place in foliage in a loose, rusty orange cocoon of silk.

The giant Crab Spider is a large spider native to the tropics; the largest reported individual had a leg span of 30 cm. This cosmopolitan spider is highly valued in some areas, as it's able to catch cockroaches and other indoor pests. Reportedly, it hunts even scorpions and bats. This spider is venomous and sometimes bites humans, but it's considered harmless.
