Top 20 Most Common Insects in Philippines

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.

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 common evening brown (Melanitis leda) changes its appearance based on the season. During wet seasons, it has a pale brown underside and a dark brown top. Then, during dry seasons, it often has more distinguished bands or spots. It uses these neutral colors to help it blend into leaves and trees. It usually only flies during the evening, resting during daylight.

The lime swallowtail (Papilio demoleus) has a beautiful black and white pattern, but it's considered a major pest to citrus trees. It feeds on nearly any type of citrus, including oranges and limes. This butterfly's small, green larvae are capable of defoliating an entire nursery grove. They are truly trouble makers in the citrus orchard.

The larvae of the black soldier fly are voracious eaters, making them excellent composters of a wide range of decomposing organic matter, including food waste and feces. The adults do not eat food - they only consume water and nectar and live off of the nutrients consumed as larvae, so they are not household pests. The larvae have been used as an important protein source for both animals and humans.

Danaus melanippus, the black veined tiger, white tiger, common tiger, or eastern common tiger, is a butterfly species found in tropical Asia which belongs to the "crows and tigers", that is, the danaine group of the brush-footed butterflies family. It ranges from Assam in eastern India through South-East Asia south to Indonesia, and eastwards to the Philippines and through southern China to Taiwan. It has around 17 subspecies, and its closest relative is the Malay tiger, Danaus affinis.

The species is on the IUCN Red List as not endangered, year of assessment 2010.

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 forewing is typically 1.1–1.4 inches in long. The body and forewing of the adult moth are green and ochre. They have silvery white dots and streaks, with a silvery band running obliquely on the forewing. The hindwing is red near its lower angle (tornus) to pinkish over other parts of the wing. It is crossed by a black bar and black veins.

The giant honey bee (Apis dorsata) is incredibly defensive of their territory. This may be related to humans' honey hunting, where honey is stolen from wild bees. Their nests are built from high, overhanging locations. Much like humans, they are unlikely to build onto an old building due to safety issues. Their nests need to be sturdy, as a colony can reach up to 100 thousand workers.
