This pic is important for me because this insect was very rare on the river Danube for tens of years,(even old sailors didn't saw it) due to the water-pollution but since 2-3 years they appeared again in the Danube. This mean the river is clear again. In spite of its English name they swarm in middle of August.

Like the visible structures on the wings.
Great details, very good wing folds. It is a good sign to reverse pollution.
The wings are spectacular, but the thorax is over-exposed. I love the look of it though.
I Like It!!!
