The Gomphidae are a family of dragonflies commonly referred to as clubtails or club-tailed dragonflies. The family contains about 90 genera and 900 species found across North and South America, Europe, Asia, Australia, and Africa. [2] The name refers to the club-like widening of the end of the abdomen (abdominal segments 7 through 9).
It is a medium sized dragonfly with dark face and greenish blue eyes. The thorax of old males are dark blue due to pruinescence. Its wings are transparent with dark amber-yellow tint in the extreme base. Its abdomen is pruinosed with blue color up to segment 8; last two segments are black.
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.
It is a medium-sized dragonfly with dark face and bluish eyes. Its thorax is also black with a broad apple green stripe on both sides.

One of the largest species in Europe, the emperor dragonfly is exceeded by magnificent emperor, which occurs only marginally in the east Mediterranean [9] and in length by females of the golden-ringed dragonfly, a species with an unusually long ovipositor. [10] Thus, in most of Europe the emperor is the largest dragonfly species present.
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.
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 ...
