Danish naturalist Klaus Bek Nielsen had an inkling something major was afoot, when a rather dapper beetle suddenly trundled across an area of good ant-lion territory on the danish island Møn. He had been out exploring with a friend for most of the day, when this beetle suddenly appeared. Closer inspection and confirmation by several experts revealed it to be a specimen of Chrysolina carnifex - as seen on this very nice photo taken by Klaus Bek Nielsen.
This is the first confirmed sighting of the beetle in Denmark since 1967. Bek Nielsen and his friend is probably the only living naturalist in Denmark to have seen this beetle. All earlier sightings were made by people who are now all dead.
