Top 20 Most Common Insects in Turkey

Orthetrum coerulescens can reach a body length of 4 - 4.5 cm. These dragonflies have a thorax with pale yellow ante-humeral stripes. In the males the color of these stripes fades with age. The abdomen is rather slim and shows an evident dorsal keel. Males have blue-grey eyes and a blue pruinescence on the abdomen, developed with age. Young males are yellow-brown. On the contrary some (androchrome) females at the end of the reproductive cycle assume the bluish color of the male. In the female the abdomen is yellowish-brown, with a thin median black line and small transverse lines to the connections of the various segments. The hyaline wings have yellow costa and a long yellow-brown pterostigma (about 4 mm). This species resembles the black-tailed skimmer but is smaller and slimmer and the male has no black tip. Females and immature males lack the black abdominal pattern.

The body length of larvae is variable and highly dependent on environmental conditions. The final stage (F-0-stage) larvae are 3.5 - 4.5 mm and weigh about 4 mg, slightly below the banded demoiselle. Calopteryx virgo can reach a body length of 5 - 5 cm, with a length of hindwings of 3 - 4 cm. These large, dark damselflies have small hemispherical eyes located laterally on the head, two pair of wings similar in shape and a slender abdomen. The basal area of the wings is transparent, otherwise wings are uniformly colored. The wings are also traversed by a dense network of veins. This species presents an evident sexual dimorphism in colour pattern. The male usually has much more extensive pigmentation on the wings than other Calopteryx species in its range: in the south east of its range (the Balkans and Turkey) the wings are entirely metallic blue while in other areas, there are clear areas at the base and tip of the wing. Immature males show brown wings, as the metallic blue wing color develops only with age. They have metallic blue-green bodies and blue-green eyes. The female has dark brown iridescent wings, a white patch near the tip of the wings (called a pseudopterostigma) and a metallic green body with a bronze tip of the abdomen.

The upperside forewings are a bright orange with a dark outside edge border and with eight or nine black spots. The hindwings are dark with an orange border. Some females also have a row of blue spots inside the orange border and are known as form caeruleopunctata. The undersides are patterned in a similar way but are paler. The black spots on the forewings are outlined in yellow and the dark colouring is replaced by a pale brownish grey. The hindwings are the same brown/grey colour with small black dots and a narrow orange border. The caterpillars (larvae) are usually green, but some have a purple stripe down the middle of the back and along each side.

It is a fairly large dragonfly (the length of 4.5 - 5 cm, 3 - 3.5 cm abdomen, rear wing 3.5 - 4 cm.) with relatively broad, flattened abdomen, but not as broad as to chaser species. With age, adult males develop extensive blue pruinescence on their abdomen, offset by yellow lateral patches. The middle lobe of the pronotum is large and notched in the middle. The chest is yellow or yellowish-brown. The base of the hind wings do not show a dark opaque spots. The pterostigma is dark brown or black. On the front wings pterostigma 2 - 3 mm long. Anal appendages are black. The females and immature males are a deep yellow color, with wavy black lines dorsally on their abdomen. Males and females have the costal vein (the leading edge of the wing) yellow or black.

The emperor dragonfly or blue emperor (Anax imperator) is a large species of hawker dragonfly of the family Aeshnidae, averaging 78 millimetres (3.1 in) in length.

Western honey bee（Apis mellifera） is the most common species of honeybee in the world. Among the first domesticated insects, its cultural and economic impact on humanity has been vast and far-reaching, providing honey, wax and its services as a pollinator. Western honey bee faces challenges worldwide, such as colony collapse disorder, and populations are thought to be decreasing.

Despite its common name, only male specimens of common blue butterfly (Polyommatus icarus) can accurately be described as blue; the females are predominately gray-brown, with only a dusting of blue and a scattering of orange spots. The adults live for only three weeks before dying.

Its labium and labrum are golden-yellow and face and frons are greenish yellow and eyes are green, bluish when aged. Its thorax is pale olivaceous brown with dark brown sutures. Its segment two of the abdomen is turquoise blue. Segment three has a large blue patch at each side. Segments 4 to 9 have an irregular black middorsal stripe. Segment 10 is black.
