Aeshna isoceles

Aeshna isoceles (or isosceles) is a small hawker dragonfly that is found in Europe, mostly around the Mediterranean, and the lowlands of North Africa. Its common name in English is green-eyed hawker. In the United Kingdom it is a localised species, and is called the Norfolk hawker.

Aeshna isoceles is brown, with green eyes, clear wings, and a yellow triangular mark on the second abdominal segment which gave rise to its scientific name. It used to be in the genus Anaciaeschna as it different in several ways from the other members of the genus Aeshna to which it now belongs.
