Fun facts
It has proper working wings, but it hardly ever bothers to fly.
Its babies are black larvae that live on the mint plant, just like their parents.
The larvae sleep through the winter, wake up in spring for a quick snack, and then turn into beetles in the soil.
A grown-up mint leaf beetle lives a long time and can survive two winters.
