Pictured here is the European rose chafer (sometimes called goldsmith beetle, or green rose chafer, or "zlatna mara" here in Croatia), which I stumbled upon during the food break at work. It was absolutely adorable, just scuttling around my arm, curiously looking around and then flew off to parts unknown, just as I took the second photo on the right. They're quite commonplace around here and while their body is mostly green color, there are some rare variations, ranging between bronze, copper, violet and blue/black.

They're considered pests due to the fact that they feed on flowers, however I personally find them cute as hell.
