Fun facts

1

Its name comes from the silver mark under its wing: a curved line and a dot, just like a question mark.

2

The mother usually lays her eggs on the wrong plants, so the tiny caterpillars must find their own food after hatching.

3

Its chrysalis takes on the colours of its surroundings, so it is very hard to spot.

4

Butterflies that hatch in late summer spend the whole winter hiding in sheltered places.

5

It is a traveller. Some of these butterflies migrate long distances.
