Top 20 Most Common Insects in Rizal
Insects in Rizal are as diverse as the regions they inhabit, from lush rice fields to balmy coastal zones. Not mere pests, these fascinating creatures play an essential function in our ecosystem. As we venture through the 20 most common insects in Rizal, we'll reveal how geography gives rise to varied insect populations, and appreciate the balance between what we see as beneficial or invasive species.

Most Common Insects

1. Ambulyx tattina
It can be distinguished from other Ambulyx species by the absence of subbasal dark patches on the forewing, and the division of the distal third sharply into pale anterior and dark posterior halves.


2. Euplocia
Euplocia is a monotypic moth genus in the family Erebidae erected by Jacob Hübner in 1819. Its only species, Euplocia membliaria, was first described by Pieter Cramer in 1780. It is found from the northeastern Himalayas to Sundaland, the Philippines, Sulawesi and the Lesser Sundas. The wingspan is about 70 mm.


3. American cockroach
Despite its name, american cockroach (Periplaneta americana) is not native to the Americas but rather to Africa and the Middle East, from which it arrived as a result of human commercial patterns. Notably quick and rather resilient, this species is capable of limb regeneration. It requires a certain level of moisture to thrive, and it will avoid drier areas unless it has access to the required level of water.

4. Common house fly
The female common house fly mates once and can store the sperm for multiple batches of eggs throughout her life. She will lay anywhere between 75 to 150 eggs at a time, usually in rotting organic matter, where the larvae will feed. The adults feed on feces and animal matter, making them important ecological composters. However, they can also transmit pathogens to human food and are considered pests and health hazards in human-occupied areas.

5. Scopula opicata
Its wingspan is 20 millimetres (0.79 in). The species is white slightly sprinkled with brown. Frons blackish. Abdomen with brown rings. Forewings with prominent oblique brown line from lower angle of cell to inner margin near base. Another line runs from apex to middle of inner margin. Three submarginal lines diverging from the apex, of which the outer two are slightly waved. A marginal line present. Hindwings with sub-basal, antemedial, and medial prominent lines. Two waved postmedial lines and a marginal line present.


6. Gray wall jumper
The female gray wall jumper lays her eggs in cracks or other hidden areas. The young and mature spiders feed on flies, making them useful residents in a household. They do not make webs, but carefully hunt and jump on their prey.

7. Xyleutes strix
Xyleutes strix is a moth of the family Cossidae. It is found in India, south-eastern Asia, Sundaland, the Philippines, Sulawesi, the Moluccas and New Guinea.


8. Common Fruit-Piercing Moth
The wingspan is about 80–94 mm in male. Palpi with third joint long and spatulate at extremity. Forewings with non-crenulate cilia in male, crenulate in female. Head and thorax reddish brown with plum-color suffusion. Abdomen orange. Forewings reddish brown, usually with a greenish tinge and irrorated with dark specks. An oblique antemedial line present, which is generally dark and indistinct but sometimes pale and prominent. Reniform indistinct. A curve postmedial line found, which is almost always met by an oblique streak from apex. Hindwings orange, with a large black lunule beyond lower angle of cell. There is a marginal black band with cilia pale spots runs from costa to vein 2. Ventral side of forewings with orange postmedial band. The wingspan is about 90–110 mm in female. Female has much more variegated and dark reddish brown striated forewings. Reniform dark and sending a spur along median nervure to below the orbicular speck. There is a triangular white mark usually present on the postmedial line below vein 3. Larva has dilated 11th somite and surrounded by a tubercle. Body purplish brown, where dorsum brown from 6th to 11th somites. Legs red and spiracular scarlet patches largest posteriorly and with some irregular white markings round them, on somite 9 in the form of an oblique white bar. There is a yellow sub-basal mark found on 4th somite. Fifth and sixth somites have black ocelli with yellow iris and white pupils. Two yellow patches can be seen on 11th somite. The adult is considered an agricultural pest, causing damage to many fruit crops by piercing it with its strong proboscis in order to suck the juice. Attempts have been made to control them using baits for the adults, egg parasites and larval parasitoids.


9. Dwarf wood scorpion
Liocheles australasiae is a species of scorpions of the family Hormuridae.

10. Psyche
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.
