Male dragonflies patrol these areas and defend them from dragonflies of both their own and other species. Females initiate mating by flying into a male's territory. A male responds to this behavior by chasing after the female. Once the male reaches the female, he latches onto her body. The two then fly to nearby shrubs, and copulation begins. [15]
Common worldwide or nearly worldwide genera are Aeshna and Anax. Anax includes some of the largest dragonflies, including the North American A. walsinghami, Hawaiian A. strenuus, European A. imperator and A. immaculifrons, and African A. tristis, but these are all exceeded by another member of the family, the Asian Tetracanthagyna plagiata, which by wingspan and weight is the world's largest ...
The flight muscles need to be kept at a suitable temperature for the dragonfly to be able to fly. Being cold-blooded, they can raise their temperature by basking in the sun. Early in the morning, they may choose to perch in a vertical position with the wings outstretched, while in the middle of the day, a horizontal stance may be chosen.

They frequently fly high up into the sky in search of prey, which includes butterflies, other odonata and tadpoles. If their hunt is successful, they eat their smaller prey while flying. The dragonflies breed in a variety of aquatic habitats from large ponds to dikes and slow-moving rivers, but require a plentiful supply of vegetation in the water.

Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the Epiophlebia damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and ...
