Top 18 Most Common Insects in Romblon

Banded coral shrimp (Stenopus hispidus) is a crustacean that occupies tropical waters in the Atlantic Ocean, the Gulf of Mexico, and reefs surrounding Australia and New Zealand. It acts as a cleaner fish, and removing parasites and fungi from other passing fish. This species is monogamous and mates for life.

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.

The adult butterfly has a wingspan of 5 - 6 cm,and exhibits seasonal polyphenism. "Upperside rich orange-yellow. Fore wing with a pale dusky and a much darker short transverse bar with lateral jet-black marginal lines across cell, another somewhat similar bar defining the discocellulars; costal margin, an inner and an outer subterminal line, and a terminal line dusky black; a large minutely white-centred ocellus with an inner slender and outer black ring on disc in interspace 2; two similar but smaller geminate subapical ocelli with an obscure pale spot above them and a short oblique bar connecting them to the black on the costa. Hind wing: a small minutely white-centred and very slenderly black-ringed discal ocellus in interspace 2, with a very much larger pale yellow and black-ringed ocellus above it spreading over interspaces 4, 5 and 6, the centre of this ocellus inwardly brownish orange, outwardly bluish black, with two minute white spots in vertical order between the two colours; finally postdiscal subterminal and terminal black sinuous lines. "Underside ochraceous brown, very variable. In most specimens the cell of the fore wing is crossed by three dark sinuous bands, the outermost along the discocellulars; these are very faint in some; both fore and hind wings crossed by a basal and a discal pale sinuous line, the latter margined outwardly by a dark shade, which is traversed by an obscure somewhat obsolescent row of dark spots, and outwardly bounded by a subterminal sinuous line, the dark shade in many cases spreading on the fore wing to the terminal edge of the wing; on the hind wing the subterminal line meets the discal in an acute angle at the tornus. Antennae dark brown; head, thorax and abdomen more or less orange-brown; paler beneath." "Upperside similar, the black markings deeper in colour and heavier, the subterminal and terminal lines more clearly defined. "Underside pale ochraceous. Fore wing: cell crossed by live short sinuous dark brown lines, a similar line on the discocellulars and another beyond it, both bent inwards at an angle and continued to the dorsum, the space between them forming a discal broad fascia, which pales to whitish posteriorly; the postdiscal ocelli, subterminal and terminal lines as on the upperside but paler. Hind wing: a slender transverse subbasal dark line, a discal whitish straight fascia in continuation of the one on the fore wing; the postdiscal ocelli, the subterminal and terminal lines much as on the upperside but paler; the anterior ocellus with a double iris and centre. Antennae dark brown; head, thorax and abdomen slightly darker than in the dry-season form.

The underside of both sexes is pale greyish brown. The underside hindwing does not have a spot in the basal area of 7. The butterfly has two tails - a 6 mm long one at V1 and a 5 mm long tail at V2. The markings include: a double bar at end-cell,a regular discal line on the forewing,a broken, less regular line on the hindwing. The male butterfly is pale blue to dark brown above, dark shining purple depending on the light. It has a black border with the upper forewing having a large black discal area of modified scales. The female butterfly is dark brown and its hindwing has a white disconnected discal band above the tornus. The butterfly also has a white-edged tornal black spot in 2.

Females grow to about 6 - 10 mm long, while males reach a size of 3 - 5 mm. Females have six abdominal spines ending in distinct sharp points. Most have two large white spots on the upper surface of their abdomens, which are otherwise mottled with black, brown, and white patterns.

Coccinella transversalis, commonly known as the transverse ladybird or transverse lady beetle is a species of ladybird beetle found from India across southern and southeastern Asia to Malesia and Australia. It is not to be confused with Coccinella transversoguttata, a widespread species in Europe and North America also known as the transverse ladybird. The alternative vernacular of small transverse ladybird may be used for C. transversalis in instances where these two species are discussed together. The transverse ladybird was first described by Danish zoologist Johan Christian Fabricius in 1781 as Coccinella transversalis and still bears its original name. Fabricius' description predated Carl Peter Thunberg's naming of this species as C. repanda by several months. Measuring 3.8 to 6.7 millimetres (0.15 to 0.26 in) long and 3.3 to 5.45 millimetres (0.130 to 0.215 in) wide, the transverse ladybird shows little variation across its wide range. It has a black head with predominantly bright red or orange elytra boldly marked with a black band down the midline and two lateral three-lobed markings.

The litchi giant stink bug (Tessaratoma papillosa) is distinguished by a yellow-brown coloring and the black part on the bottom part of its body. Females in this group can be almost double the size of the males. Regardless of their size, they are considered a major pest of fruit trees, as they suck the sap from these trees.

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.
