Top 20 Most Common Insects in Sudan

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.

Orthetrum trinacria, the Long Skimmer, is a species of dragonfly in the family Libellulidae. It is found in Algeria, Angola, Botswana, Burkina Faso, Cameroon, Ivory Coast, Egypt, Ethiopia, France (Corsica), Gambia, Ghana, Italy (Sicily and Sardinia), Kenya, Libya, Madagascar, Malawi, Mali, Morocco, Mozambique, Namibia, Niger, Nigeria, Senegal, Somalia, South Africa, Tanzania, Togo, Uganda, Zambia, Zimbabwe, and possibly Burundi. It was recently recorded in the Maltese Islands in 2003 and was recorded breeding on the island of Gozo in 2004. Its natural habitats are rivers, shrub-dominated wetlands, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, and intermittent freshwater marshes. Also breeding in Southern Spain (Murcia and Malaga Provinces) and the Canary Islands.

The species is on the IUCN Red List as not endangered, year of assessment 2007.

Papilio demodocus , also known under the English name Citrus Swallowtail ("Citrus Swallowtail"), is a butterfly from the family of the knight butterflies (Papilionidae).

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.

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.

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.

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:

The face of the mature male is deep red, the vertex and top of the frons having a purple sheen. The eyes are deep red and the labium deep yellow with a dark brown stripe in the centre. The synthorax is red with black stripes; mature males often have a purple bloom on the upper thorax.The wings have bright red veins and orange makings at their bases. The pterostigmas are 2.5 - 2.5 mm long and dark brown. The slender abdomen is bright red; S6-S8 have black wedges on each side; S9 and S10 are black. Females have similar markings, but the abdomen and face are yellow to yellowish brown. The sides of the synthorax are pale yellow-brown, as are the lower sides of S1-S3.
