Odonata, insect order comprising the dragonflies (suborder Anisoptera) and the damselflies (suborder Zygoptera). The adults are easily recognized by their two pairs of narrow, transparent wings, sloping thorax, and long, usually slender body; the abdomen is almost always longer than any of the wings.

Odonata: dragonflies and damselflies. Characteristics These often brightly coloured, fast flying insects are well known and easily recognised. Dragonflies and damselflies are medium to large insects with body lengths ranging from 15-120 millimetres. They are often seen flying rapidly over streams and lakes, or through gardens at dusk, often.
Odonata are typically generalists with few exceptions. Diptera, especially mosquitoes and midges, are a major component of the adult diet.

Odonata (dragonflies and damselflies) are well-known but often poorly understood insects. Their phylogeny and classification have proved difficult to understand but, through use of modern morphological and molecular techniques, is becoming better understood and is discussed here.
Remember: In a classification essay, the author organizes, or sorts, matters into categories. There are three steps to recollect while writing an effective category essay: organize matters into beneficial categories, use a unmarried organizing principle, and deliver examples of things that in shape into every class.

The Odonata are an order of flying insects that includes the dragonflies and damselflies. Like most other flying insects (flies, beetles, Lepidoptera and Hymenoptera), they evolved in the early Mesozoic era.
Odonata Stamp: In Japan, this dragonfly (Boninthemis insularis) is known as “Shimaakane”. The Japanese government offically designated this species a national landmark on March 12, 1969. This stamp (one of four in a set illustrating insects) was issued on September 14, 1977.
Members of the Ohio Odonata Society are engaged in a variety of research projects. Many involve survey work, but some are more applied. These links will take you to sites highlighting some of that research.
Both dragonflies and damselflies belong to the Odonata, which is a subgroup of insects, which in turn is a group of uniramian arthropods.Many characteristics distinguish Odonata from other groups of insects -- minute antennae, extremely large eyes (filling most of the head), two pairs of transparent membranous wings with many small veins, a long slender abdomen, an aquatic larval stage (nymph.
Insects within the Order Odonata are commonly called the dragonflies and damselflies. They are often large and conspicuous insects and can be found patrolling territories above ponds and other water bodies. Both the adults and larvae are predators. The adults often catch prey on the wing and the larvae ambush other aquatic organisms.
Trueman and Rowe (2009) and Dijkstra et al. (2013) summarize the issues and relevant literature in Odonata phylogenetics; the latter outlines the most recent and probably the most widely accepted classification. Odonata is monophyletic and is divided into three suborders: Anisoptera (true dragonflies), Anisozygoptera and Zygoptera (damselflies), although some controversy over this.
Global Biodiversity Information Facility. Free and Open Access to Biodiversity Data.Dragonfly, (suborder Anisoptera), any of a group of roughly 3,000 species of aerial predatory insects most commonly found near freshwater habitats throughout most of the world. Damselflies (suborder Zygoptera) are sometimes also called dragonflies in that both are odonates (order Odonata).Odonata definition is - an order of insects containing the dragonflies and damselflies and characterized by aquatic larvae that are nymphs or naiads and by predaciousness in both adult and larval forms.
