Light coloured individues of Aeshna juncea
near Erzurum, Eastern
Turkey

 

On 25 August 2002 in North-eastern Turkey, we found a male Aeshna juncea with extensive yellow on the thorax. I had seen such males in the collection of the RMNH which were collected by Gert-Jan van Pelt also near Erzurum, but in the hand it was even more obvious.

The male (right) has more yellow on its side of the thorax as the nominal subspecies. Also there is a large yellow spot present between the hind legs (under the thorax). .

The habitat were the male was caught: a valley South of Boyaz near Palandöken, south of Erzurum, at 2700 m a.s.l..
A number of subspecies has been described within Central-Asia. But Oleg Kosterin wrote me. "Russian literature seems to speak nothing of such unique dragonflies". Furthermore Jean-Pierre Boudot send me a picture of a female of Aeshna juncea. As shown below this one has no sign of such extensive yellow markings.

We also took a look at the individuals collected by Gert Jan van Pelt present in the Leyden museum, The Netherlands (RMNH). The scans are presented below.
It turns out the other male from Erzurum has a different yellow pattern on the thorax. Although both have extensive yellow on their thorax, it must be attributed to the southern locality rather than a different subspecies. Two males from the Savsat area had normal markings.
