Anax immaculifrons, [2] the magnificent emperor, [1] or blue darner, [3] is a species of dragonfly in the family Aeshnidae.Almost all its range is in West and South Asia (the population further east in Asia is now recognized as a separate species, A. aurantiacus); it is Europe's largest dragonfly but very marginal in the continent where restricted to some Aegean Islands and Cyprus.
This is a list of species of damselflies and dragonflies recorded in Australia. Common names of species are linked, beside their scientific names. The list is split into two groups: damselflies (suborder Zygoptera) and other dragonflies (infraorder Anisoptera). Those groups are organized in Families and then Genera and Species.
A particular perch may give a dragonfly a good view over an insect-rich feeding ground; males of many species such as the Pachydiplax longipennis (blue dasher) jostle other dragonflies to maintain the right to alight there. [50] Defending a breeding territory is common among male dragonflies, especially in species that congregate around ponds.
The aqua blue face of the blue-faced, green/turquoise when dead meadowhawk may not be obvious to a casual observer, but it is an important field mark distinguishing it from similar-looking meadowhawks in the genus Sympetrum, such as Sympetrum vicinum. This small dragonfly reaches a maximum total length of 38 mm. The thorax is grayish or olive ...

[11] [3] Depending on the viewing angle, the dragonfly's wings can vary in color due to their light scattering properties, with some appearing golden in the light.
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 ...
