English name: Eastern spectre 

Like all members of the emperor dragonfly family, it spends most of its time patrolling its territory and driving away any intruder. The flight of the spectre is somewhat zigzag, and it scans every corner and every crevice in its territory.

Size: medium (5-6 cm).
Habitat: flowing streams with plants and trees growing in them. It prefers brooks with stones, and avoids very large channels.
Usually the spectre rests on trees above the water.
Distribution: the Balkans and Turkey.
Rare in the country.
Season: . mid-May to mid-August (according to data from Turkey).

Identification marks:
On the head (white in adult males, and yellow in females and young), there is a prominent black stripe at the front of the eyes.
The thorax is brown and has two large and prominent antehumeral shoulder stripes (blue in the male and yellow in the female), and on its sides there are two prominent light stripes.
The abdomen is black and has light blue spots (in the male) or yellow (in the female).
The pterostigma is very short and dark.

The male form is unique and should not be confused with any other local species. But at a glance the female may appear similar to the female of mosaic darter.
