Top 20 Most Common Insects in Namibia
Insects, creatures as diverse as their habitats, don their unique roles across Namibia's varied landscapes. This insect diversity is heavily influenced by geographical location, with different factors like Namibia's climate and ecosystem playing significant roles. By shaping Namibia's environments, these insects either enhance our lives or become the bane of it. As we delve into the 20 most common insects in Namibia, we'll see how tightly they're woven into the country's ecological fabric.
Most Common Insects
1. Kirby's dropwing
The spotted sun pointer (Trithemis kirbyi) is a dragonfly species from the family of the dragonflies (Libellulidae). Two subspecies are described. The nominate subspecies occurs in India and Sri Lanka, while the insufficiently defined taxon Trithemis kirbyi ardens occurs in the rest of the distribution area, which mainly includes Africa.
2. Danaid eggfly
The danaid eggfly (Hypolimnas misippus) is a unique butterfly where females tend to have a strong advantage. Males are identified by being blackish with white spots. Females exhibit polymorphism, or the ability to have multiple forms. This means that they can resemble males in some cases, but also resemble toxic butterflies like the Monarch butterfly.
3. Zebra white
The wingspan is 4 - 6 cm in males and 4 - 4.5 cm in females. 
4. Pioneer white
Wet-season form. The upperside of males is white with the forewing having the costa from base to base of vein 11 dusky black and then jet black continuing into a widened and curving short streak along the discocellulars to the lower apex of the cell; apical area diagonally with the termen black, the former with six elongate outwardly pointed spots of the ground colour enclosed one in each of the interspaces 3, 4, 5, 6, 8, and 9. Hindwing: uniform, the black along the venation on the underside seen through by transparency; termen between veins 2 and 6 somewhat broadly black, with a series of four round spots of the ground colour in the interspaces; below vein 2 and above vein 6 the termen is very narrowly black. Underside: forewing white, markings similar, more clearly defined, the white spots within the black apical area larger. Hindwing: yellowish white, all the reins very broadly bordered with black; interspaces 1, 2, 6, and 7 with crossbars of black, beyond which there is a subterminal, somewhat broad, transverse band of black between veins 2 and 6. Cilia of both forewings and hindwings white alternated with black. The ground colour on both upper and undersides variable, often cream coloured above; beneath: in some specimens, the base of cell and the elongate spots in apical area of forewing, and the whole surface of the hindwing varies to rich chrome yellow. Female similar; the black markings on both upper and undersides broader, the white spots on black apical area of forewing often sub-obsolete above. Antennae in both sexes black, sparsely sprinkled with white dots; head, thorax and abdomen above and below white: thorax above often bluish grey. Dry-season form. The dry-season form is similar to the wet-season form but on the upperside the black markings are narrower, the white markings on the black apical area of forewing broader and longer, and on the hindwing the narrow inner margining to the black on the termen very narrow, somewhat obsolescent; therefore, the white subterminal spots have the appearance of opening inwards. Underside: ground colour almost pure white; on the hindwing slightly tinged with yellow. Antennae, head, thorax, and abdomen as in the wet-season form. Wingspan of 4.5 - 6 cm.
5. Yellow pansy butterfly
The male upperside is bright yellow. The costa of the forewing has a broad triangular jet-black projection downwards at the discocellulars, and the dorsum has a triangular projection upwards near the tornus; this black margin narrows near the middle of the termen and bears on the apex two short transverse preapical white streaks crossed by the black veins. Below these is an obscure ocellus that is sometimes absent. The anterior half and the terminal margin of the hindwing is black, and the dorsum is broadly shaded with brown while the anterior black area has a large brilliant blue spot. The cilia of both forewings and hindwings are white alternated with brown.The underside of the forewing is pale yellow. The cell is crossed by three laterally black-margined orange-yellow bars, beyond that is a short, broad, irregular jet-black oblique band from costa to base of vein 4. The hindwing is greyish yellow, and in the dry season its form is strongly irrorated (sprinkled) with dusky scales. With a prominent transverse brown discal fascia, its margins are highly sinuous. There is a brownish broad shade on the middle of the termen and some obscure lunular marks on the basal area. The antennae is pale, and the head, thorax and abdomen are dark brownish black; beneath that is a dull ochraceous white. The female is similar, although the colours are duller. The cell of the upperside forewing has a more or less complete transverse black fascia and another at the discocellulars. A blue-centred well-marked ocelli is in interspaces 2 and 5 on the disc of the forewing, and smaller ocelli in interspaces 2 and 5 on the disc of the hindwing. The forewings and hindwings have a fairly well-defined pale subterminal line, though the blue spot on the anterior black area on the hindwing is small and ill-defined; the rest is as the male. The underside is also as the male, but generally has heavier and more clearly defined markings.
6. Cream-striped owl
Cyligramma latona has a wingspan reaching 8 - 10 cm. The uppersides of the wings are brown, with a yellowish band crossing all the wings and a large eyespot on the forewings.
7. Painted lady
The painted lady is a migratory butterfly that spends part of the year in Northern Africa and then migrates to Europe during the warmer months. Although the adults feed on nectar from flowers, the larvae feed on the leaves of nettles and thistles.
8. Scarlet dragonfly
Crocothemis erythraea can reach a length of 3.5 - 4.5 cm. These dragonflies haves a flattened and rather broad abdomen. The adult male scarlet dragonfly has a bright scarlet red, widened abdomen, with small amber patches at the bases of the hindwings. Also the veins on the leading edges of the wings are red. Females and immatures are yellow-brown and have a conspicuous pale stripe along the top of the thorax.
9. Silver-striped hawk-moth
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.
10. African social spider
This spider has been studied living in large colonies or family groups, in unkempt and messy webs. Due to slow female maturing only about 40% of them get to mate. The other 60% have been dubbed "virgin spiders" and they share in childcare duties alongside their sisters. The female feeds instar at the second stage by regurgitation and by providing them with captured prey, where in final instars, mother female devoted her life for the babies to use her body fluids and then dies. The males of this species die shortly after mating.
