A dragonfly is an insect belonging to the order Odonata, infraorder Anisoptera (from Greek ἄνισος anisos, "uneven" and πτερόν pteron, "wing", because the hindwing is broader than the forewing). Adult dragonflies are characterized by large, multifaceted eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Dragonflies can be mistaken for the related group, damselflies (Zygoptera), which are similar in structure, though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold the wings folded at rest, along or above the abdomen. Dragonflies are agile fliers, while damselflies have a weaker, fluttery flight. Many dragonflies have brilliant iridescent or metallic colours produced by structural coloration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each.
Ngô Đình Cẩn (1911 – 9 ọnwaìse 1964) bụ̀rụ̀ a younger brother and confidant ǹke okeisi ìzìzì ǹkè nledà Vietnam, Ngô Đình Diệm, and an important member of the Diệm government. Diệm put Cẩn in charge of central Vietnam, stretching from Phan Thiết in the south to the border at the 17th parallel, with Cẩn ruling the region as a virtual dictator. Based in the former imperial capital of Huế, Cẩn operated private armies and secret police that controlled the central region and earned himself a reputation as the most oppressive of the Ngô brothers.
 
Fossils of very large dragonfly ancestors in the Protodonata are found from 325 million years ago (Mya) in Upper Carboniferous rocks; these had wingspans up to about 750 mm (30 in). About 3000 species of Anisoptera are in the world today. Most are tropical, with fewer species in temperate regions.
In his youth, Cẩn was a follower of the nationalist Phan Bội Châu. In the late 1940s and early 1950s, he worked to organise support for Diệm as various Vietnamese groups and international powers sought to stamp their authority over Vietnam. Cẩn, who succeeded in eliminating alternative nationalist opposition in central Vietnam, became the warlord of the region when his brother became president of the southern half of the partitioned nation in 1955. He became notorious for his involvement in smuggling and corruption, as well as his autocratic rule. Cẩn was regarded as an effective leader against the Viet Cong communist insurgency, which was much weaker in central Vietnam than in other parts of South Vietnam. His Popular Force militia was regarded by US officials in central Vietnam as a successful counter to the communists.[1]
 
Dragonflies are predators, both in their aquatic larval stage, when they are known as nymphs or naiads, and as adults. Several years of their lives are spent as nymphs living in fresh water; the adults may be on the wing for just a few days or weeks. They are fast, agile fliers, sometimes migrating across oceans, and are often found near water. They have a uniquely complex mode of reproduction involving indirect insemination, delayed fertilization, and sperm competition. During mating, the male grasps the female at the back of the head or on the prothorax, and the female curls her abdomen under her body to pick up sperm from the male's secondary genitalia at the front of his abdomen, forming the "heart" or "wheel" posture.
Cẩn's influence began to wane after his elder brother Ngô Đình Thục was appointed the Roman Catholic Archbishop of Huế. Thục overshadowed Cẩn and aggressively promoted Catholicism, which led to the banning of the Buddhist flag in 1963 during Vesak, the celebration of the birthday of Gautama Buddha. Cẩn's forces opened fire on a crowd who were protesting the ban, killing nine and precipitating the Buddhist crisis. Ongoing demonstrations intensified throughout the summer as the regime responded with increased brutality, sparking the toppling of the Diem regime in a November 1963 coup. Cẩn had been offered asylum by the US Department of State, but ambassador Henry Cabot Lodge, Jr. had CIA agent Lucien Conein arrest the fallen Ngô in Saigon. Cẩn was turned over to the military junta, which tried and executed him in 1964.
 
Loss of wetland habitat threatens dragonfly populations around the world. Dragonflies are represented in human culture on artifacts such as pottery, rock paintings, and Art Nouveau jewellery. They are used in traditional medicine in Japan and China, and caught for food in Indonesia. They are symbols of courage, strength, and happiness in Japan, but seen as sinister in European folklore. Their bright colours and agile flight are admired in the poetry of Alfred, Lord Tennyson and the prose of H. E. Bates.
