Banded Demoiselle

Last week’s hot spell gave me the gift of quite a few minutes spent watching and photographing these magical banded demoiselle damselflies, by the lake outflow stream in Tatton Park. These are larger than the average damselfly, almost of a size more typical of dragonflies.

Their colours are startling blues and greens in bright sunlight. According to the British Dragonfly Society, the two genders are distinguished as follows:

  • Male: metallic blue body with broad dark blue-black spots across outer parts of wings.
  • Female: metallic green body with translucent pale green wings. (Wikipedia suggests there may also be a white patch near the tip of the female’s wings).

Most of these are pobably males, or maybe not?

Banded agrion

This beautiful large blue damselfly is described as a banded demoiselle by Wikipedia, or banded agrion in our old butterfly book. By damselfly standards this is large, around 2 inches long. This one is a brilliant iridescent blue, they can be blue-green. The most distinctive feature is the large dark patch on the wing.

Seen commonly in Europe and Asia. This one paused conveniently by the River Vézère in the Dordogne region of France, late summer 2018.
