Small tortoiseshell
The small tortoiseshell is a bright orange butterfly with black and yellow patches and a row of little blue spots along the edges of its wings. When it folds its wings, the underside is dull brown, so it hides well. It is one of the first butterflies you see on warm spring days.

Fun facts
It sleeps through the winter as a grown-up butterfly and wakes up on the first warm, sunny days of the year.
Its caterpillars live together in a big group on nettle leaves.
In warm places it can have two families of babies in one summer, but in the cold north only one.
It is the national butterfly of Denmark.
Dry summers are bad for it, because the nettles get dry and the caterpillars do not find enough good food.
