Common blue damselfly

  • Scientific name: Enallagma cyathigerum
  • Type: Insects

Key information

The male has a blue abdomen with black spots; the female comes in two colour forms and is either blue or dull green. This species is common throughout Britain.

They appear to drift through the air, and they snatch their prey from vegetation. Damselflies rest with their wings folded lengthways along their body.

During mating, the male clasps the female by her neck while she bends her body around to his reproductive organs – this is called a mating wheel. The pair flies together over the water and eggs are laid within a suitable plant, just below the surface.

The eggs hatch and the larvae, called nymphs, live in the water. Nymphs climb out of the water up a suitable stem to moult into damselflies.
