	De Tuingids - Libellen: Inleiding
		In Zygoptera is het abdomen slank en cilindrisch, in Anisoptera meestal breed en afgeplat.
		Het mannetje grijpt met de tangvormige anale aanhangsels (cerci en anaalklep) het vrouwtje bij de prothorax in Zygoptera, of bij de kop in Anisoptera, en vliegen enige tijd in tandem.
		Zowel de Zygoptera als de Anisoptera zouden kunnen zijn ontstaan uit een Anisozygoptera-achtige voorouder, of de Anisozygoptera en Anisoptera zouden elkaars naaste verwanten zijn.

		In Zygoptera the two pairs of wings are almost exactly equal in shape, size and venation.
		Carle and Wighton (1990) derived a polyphyletic Zygoptera by convergent reduction in the wing veins from anisopteran ancestors.
		The monophyly of the Zygoptera is supported by six characters, the two most important being the transverse head structure and the widely separated eyes, considered as derived characters.

	Odonata: Dragonflies and Damselflies
		The order Odonata ("toothed ones") includes some of the most ancient and beautiful insects that ever roamed Earth, as well as some of the largest flying invertebrates ever to have lived.
		While both dragonflies and damselflies belong to the Odonata and share many common features, then are a number of noticeable differences as well.
		Zygoptera copulate while perched, sometimes flying to a new perch.

	The European Odonates(Dragonflies and Damselflies)
		The difference between Anisoptera and Zygoptera is clearly visible in the shapes of the wings: Zygoptera have hind wings shaped equally to the front wings, with only two antenodal crossveins (veins perpendicular to the costa, situated at the front of each wing).
		Male Zygoptera have two pairs of anal appendages: the upper appendages (appendices superiores) and the lower appendages (appendices inferiores).
		The shape of the appendages of a species is typical for that species and corresponds with the shape of the female’s prothorax (Zygoptera), which prevents bastardising.

	flight
		It is also used by calopterygid Zygoptera as a display flight, showing off the coloured wings.
		Thrust is generated both by the movement of the wing through the air and by the twisting of the wing (supination/pronation) at the ends of each stroke.
		A remaining conundrum is the libellulid dragonflies that perch with their wings low, pointed well forward, and twisted to be near vertical.

	Dragonflies and Damselflies (Insecta: Odonata)
		Odonata was until recently composed of three suborders: Anisoptera, commonly known as dragonflies; Zygoptera, commonly known as damselflies; and Anisozyoptera, as the name denotes, a morphological composite of the previous two suborders.
		To facilitate the discussion of North American odonates it is useful to use the names Zygoptera and Anisoptera when discussing differences between the damselflies and dragonflies, as there are no extant Anisozygoptera in North America.
		There are a number of species that disperse away from water for a time before returning with a mate to breed and deposit eggs.

		The females sometimes have an ovipositor under abdominal segments 9-10 with which to lay their eggs, and the males always have secondary genitalia under segments 2-3.
		The largest Dragonfly in the world now is actually a Damselfly (Zygoptera) Megaloprepus caerulata from Costa Rica with a wingspan of 19.1 cm or 7.52 ins and a body length of 12 cm or 4.72 ins.

	Odonata Suborders (Site not responding. Last check: 2007-10-15)
		Today, there are about 5,000 species grouped into three extant suborders: Zygoptera - damselflies (Figure 1); Anisoptera - dragonflies (Figure 2); and Anisozygoptera, a small suborder of two Asian species morphologically intermediate to the former two groups.
		Two of the world's three suborders - Anisoptera and Zygoptera - are found in Michigan.
		Larvae of almost all species are aquatic, respiring by means of gills (internal with Anisopera, external with Zygoptera, the later that may also cutaneously respire).

		Damselflies are of the suborder Zygoptera and are smaller and slimmer than dragonflies, and generally hold their wings together when resting.
		Generally damselfly nymphs have slender bodies with leaf-like gills at the tail end and shades of green and brown seem to be common.
		Zygoptera have a wide distribution from tropical to temperate zones and tolerate poor water conditions.

		The Zygoptera (UK: damselfly, DK: vandnymfer) living in Denmark, 19 registred species, represent only a small portion of the close to 2000 species world wide.
		The suborder Zygoptera is one of three in the insect order Odonata.
		To the far right, each species is listed under the genus, and species from the same genus has same colour.

		Damselflies are similar to dragonflies, but the adults can be differentiated by the fact that the wings of most damselflies are held along the body when at rest, either horizontally or slightly down and forward.
		The insect family Coenagrionidae is found in the Order Odonata and the suborder Zygoptera.
		The Zygoptera are the damselflies, which although less known than the dragonflies, are no less common.

		The character featured matches the character used in the identification key.
		Odonates are separated into two subfamilies: Zygoptera (Damselflies) and Anisoptera (Dragonflies).
		Zygoptera have long narrow abdomens with gills coming off the end, whereas Anisoptera are more stout-bodied with no visible gills on the outside of their body.
