How do you identify Odonata?
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) with posterior tracheal gills, and a prehensile labium ( …
What family is Odonata?

What is the family of a damselfly?
The insect family Coenagrionidae is placed in the order Odonata and the suborder Zygoptera. The Zygoptera are the damselflies, which although less known than the dragonflies, are no less common. More than 1,300 species are in this family, making it the largest damselfly family.
Are Odonata Holometabolous?
Odonata (dragonflies and damselflies) are insects with an incomplete metamorphosis (hemimetabolous).
Where do larval forms of members of Order Odonata live?
Odonate larvae (nymphs) live in the water, a life stage that can last several years. During this period, the nymphs pull water through their gills to capture oxygen, and their “exhale” helps propel them through the water.
Is Odonata Paraphyletic?
Systematics and taxonomy. This order is closely related to mayflies and several extinct orders in a group called the Paleoptera, but this grouping might be paraphyletic.
What level of classification is Odonata?
Odonata, meaning “toothed-ones,” comprises over 5,000 living species, all of which are assigned to suborders Zygoptera (damselflies) and Anisoptera (dragonflies).
How many families of dragonflies are known?

What are the suborders of the Odonata?
The Odonata are divided into 3 suborders. Only 2 of these suborders have representative species found in Australia and these separate the robust dragonflies, suborder Anisoptera from the more delicate damselflies of the suborder Zygoptera. Follow the links below to find out more about the families of dragonflies and damselflies.
What is the origin of the Odonata?
Odonata and their ancestors come from one of the oldest winged insect groups. The fossils of odonates and their cousins, including Paleozoic “giant dragonflies” like Meganeuropsis permiana from the Permian of North America, reached wing spans of up to 71 cm (28 in) and a body length of 43 cm (17 in), making it the largest insect of all time.
Are Odonata hemimetabolous?
Because of this, Odonata are said to be hemimetabolous, or undergo an “incomplete” or “gradual” metamorphosis. Larval Odonata : Dragonflies and damselflies begin their lives as nymphs, living underwater for a year of more.
How many species of dragonflies are in the order Odonata?
This order is very diverse with about 5000 species, and its members are easy to observe. Adult Odonata : At left, an adult dragonfly (Anisoptera). Notice the relatively stout body, and the wings extending to each side while the dragonfly is perched.
