Banded Demoiselles, featured yesterday, are so highly territorial that I watched these two males for 15 minutes, in an utterly fascinating, extremely speedy and acrobatic aerial battle over a few feet of canal. Very hard to photograph but beautiful to watch, especially with perfect reflections of both as they flew.
I had to give up before they resolved the conflict. The male guards the female closely while she lays her eggs and both male and female, so deft and fast in flight, catch insects on the wing. Conditions: Sunny intervals. Temperature: Max 20- Min 12C.
