There were many beautiful flowers in the Rammelwaard. Like these grass rush flowers.
And like these chamomile flowers.
And this male common blue butterfly, also on a purple lythrum flower.
These two blue butterflies were mating. Usually, it is difficult to photograph butterflies, as they move often and fast. However, these two stayed at the same spot for half an hour. Still, it was not easy to tell which species this male (left) and female (right) were: common blue or brown argus? Common blue, I think after all. The photo shows fluid passing between the bodies of these two butterflies.
