Red-eyed Damselfly (Erythromma najas)
This strongly flying damselfly prefers larger pools with floating vegetation. Males will choose a large floating leaf and make it the base for their territory. When they mate it is usually in tandem, with the female laying her eggs into the stems of water lily leaves, sometimes disappearing under the water to find the ‘right’ stem before floating up to the surface again. They are on the wing from early June to early August.
