Aeshna isoceles
Aeshna isoceles, mating wheel. Still a mystery to figure why this species is still active and alive in middle autumn. This observation is a very late record for the species. Probably there were two generations this year. First of early May, second from August or even from early September. Next year, will be the year for answers.

"Aeshna isoceles" 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 Britain it is a rare and local species and is known as the Norfolk hawker.
