Large white

This week I found another caterpillar, on the windowframe.

Almost destroyed it, because I had not seen that the caterpillar
already had woven a safetybelt, around his body,

that meant that it was on its way to cocoon too!
And so it was...a day later it had transformed into a beautiful cocoon,
which changed colors the next day, and got beautiful spots everywhere.

the caterpillar is from the 'large white',(Groot Koolwitje) butterfly....
I guess... that this one is too a wintercocoon.
so next year?
