Top 20 Most Common Insects in Karachi

Although the indianmeal moth got its name from its tendency to eat "Indian meal" or cornmeal, it is not native to India. The larvae are able to bite through plastic and cardboard, allowing them to enter even sealed containers of cereals, fruits, and other food products.

Camponotus compressus is a type of ground-nesting species of ant found in India and Southeast Asia. It is a frequent visitor to toilets as it consumes urea. It is one of the many species which tends plant-sap-sucking insects like aphids and tree hoppers. They add nutrients into the soil through their discarded waste piles These ants stroke their antenna on the hind parts of these insects stimulating them to excrete a sugar rich liquid, called honeydew, which the ants consume. In return, they are known to protect the insects from predators like ladybugs.

Adanson's house jumper is a type of jumping spiders that can be found in areas with a warm climate. The male spiders have sometimes been found to eat young female spiders, though it is unclear why this behavior occurs. They primarily live on walls in houses and feed on mosquitos.

Aptly named, the cockroach egg parasitoid wasp is known for parasitizing cockroaches. The females lay their eggs inside of the cockroach's egg casing, and when the larvae hatch, they can feed off of the cockroach eggs. This process of inserting the eggs requires quite a bit of physical effort and maneuvering lasting, typically lasting up to thirty minutes.

The wingspan is 2 - 2.5 cm.

D. chrysippus is a medium-sized butterfly with a wingspan of about 7–8 cm (2.8–3.1 in). The body is black with many white spots. The wings are orange, the upperside brighter and richer than the underside. The apical half of the forewing is black with a white band. The hindwing has three black spots in the center. The wings are bordered in black and outlined with semicircular white spots. This species exhibits slight sexual dimorphism, as the Male has large scent glands on his hindwings, which the female lacks. They appear as a large black spot with a white centre if viewed from the underside D. chrysippus is a polymorphic species, so the exact coloring and patterning vary within and between populations. It is similar in appearance to the Indian fritillary (Argynnis hyperbius), which may coexist with it.

A. florea is called the dwarf honey bee due to its small size compared to other honeybees. A worker is typically 7–10 mm in body length and its overall coloration is red-brown. A colony builds a single, exposed comb usually on tree branches or shrubs. A. florea produce honey that is harvested and eaten in Thailand and Cambodia. They are excellent pollinators, which gives them an important ecological role in the places they inhabit. Drones carry a thumb-like bifurcation called the basitarsus, which is located two-thirds along the length of the tibia. The fimbriate lobe of A. florea has three protrusions and they sting using two stylet barbs. Apis florea and its sister species together comprise the subgenus Micrapis, and are the most primitive of the living species of Apis, reflected in their small colony size, and simple nest construction. The exposed single combs are built on branches of shrubs and small trees. The forager bees do not perform a gravity-oriented waggle dance on the vertical face of the comb to recruit nestmates as in the domesticated Apis mellifera and other species. Instead, they perform the dance on the horizontal upper surface where the comb wraps around the supporting branch. The dance is a straight run pointing directly to the source of pollen or nectar the forager has been visiting. The distinctiveness of the two species A. florea and A. andreniformis was established unequivocally in the 1990s. A. florea is redder and old workers always have a red first abdomen (younger workers are paler in colour, as is the case in giant honey bees); A. andreniformis is generally darker and the first abdomen segment is completely black in old bees. Distinguishing characteristics of the dwarf honey bees are outlined below:

Selysiothemis nigra, the black pennant, is a monotypic species of dragonfly in the family Libellulidae. It occurs in Central Asia and the Middle East. In Europe it is mostly confined to the coastal areas of the Mediterranean and the Black Sea.

Polistes stigma is a species of paper wasp from Southeast Asia.

Xylocopa fenestrata, or Xylocopa (Ctenoxylocopa) fenestrata, is a species of carpenter bee. It is widely distributed in Asian countries and very few African countries such as Madagascar and Seychelles. It is considered as a pest of timber and bamboo, but is also a valuable pollinator.
