Top 20 Most Common Insects in Jakarta
Insects, a diverse group characterized by their segmented bodies and jointed limbs, find distinct abodes across diverse city landscapes. Against the bustling backdrop of Jakarta, geographical differences foster unique insect populations. These creatures, both pests and benefactors, play pivotal roles in the ecosystem. Our insightful list of 20 most common insects in Jakarta will underline the vital nexus between ecology and entomology that exists within a metropolis.
Most Common Insects
1. Blue moon butterfly
Hypolimnas bolina, the great eggfly, common eggfly or in New Zealand the blue moon butterfly is a species of nymphalid butterfly found from Madagascar to Asia and Australia.
2. Autumn leaf
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.
3. Weaver ant
The weaver ant can be found in silk-woven nests in the foliage of Southeast Asia and Oceania. These ants have a painful bite and prey on other small insects. Larvae have many uses for local regions, including being a popular fishing bait and a good choice of bird food.
4. Slender skimmer
The species is on the IUCN Red List as not endangered, year of assessment 2009. The slender bank dragonfly occurs from Southeastern Europe and North Africa to Japan and Australia
5. Chocolate argus
Junonia hedonia is a butterfly from the Nymphalidae family. The scientific name of the species was first validly published in 1764 by Carl Linnaeus.
6. Scarlet skimmer
The species is on the IUCN Red List as not endangered, assessment year 2011, the trend of the population is increasing according to the IUCN.
7. Blue pansy
Male upperside: somewhat more than half the forewing from base velvety black, apical half dull fuliginous; cell-area with or without two short transverse orange bars; a blue patch above, the tornus; the outer margin of the basal black area obliquely zigzag in a line from the middle of costa to apex of vein 2, including a large discal, generally obscure ocellus, which, however, in some specimens is prominently ringed with orange yellow. Beyond this a broad white irregularly oblique discal band followed by a short oblique preapical bar from costa; a small black orange-ringed ocellus beneath the bar, a subterminal continuous line of white spots in the interspaces and a terminal jet-black slender line; cilia alternately dusky black and white. Hindwing blue shaded with velvety black towards base; a postdiscal black white-centred orange and black-ringed ocellus in interspace 2, a round minutely white-centred velvety-black spot (sometimes entirely absent) in interspace 5; the termen narrowly white, traversed by an inner and an outer subterminal and a terminal black line; cilia white. Underside forewing: basal half with three black-edged, sinuous, broad, ochraceous-orange transverse bands, followed by the pale discal baud; ocelli, preapical short bar, subterminal and terminal markings much as on the upperside; the discal band margined inwardly by a broad black angulated line which follows the outline of the black area of the upperside. Hindwing irrorated (sprinkled) with dusky scales and transversely crossed by subbasal and discal slender zigzag brown lines and a postdiscal dark shade, on which are placed the two ocelli as on the upperside; subterminal and terminal faint brown lines, and a brownish short streak tipped black at the tornal angle below the lower ocellus. Female. Similar, with similar but larger and more clearly defined ocelli and markings; the basal half of the forewings and hindwings on the upperside fuliginous (sooty) brown, scarcely any trace of blue on the hindwing. Antennae brown, head reddish brown, thorax and abdomen above brownish black: palpi, thorax and abdomen beneath dull white.
8. Indonesian red-winged dragonfly
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.
9. Black planthopper
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.
10. Black-and-white spiny spider
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.
