08 April

A sunny day with weak but cool winds and 13°C (12:40 PM) that turned out to be ideal for plenty of butterflies.

Three species decided to start their respective spring generations two weeks sooner than usual, whereas N. polychloros was once again only seen flying towards the very tiny forest crossing Zone I and II.

Speaking of this forest, I never really took a closer look at it since it's rather hard to access most of the time. Even now I only could take a better look at its northern edge revealed that it's a "Niederwald" where coppicing is being practiced. It is largely dominated by maples, though some other trees such as some cherries and oaks are hidden in-between. I'll try to reach it from the other side at another time.
