Chrysalises and imago of ladybug

In a warm day in winter, 

I found chrysalises on a tree. 

This was white-orange one.

Was it immediately after casting off?

Accumulated temperature was enough to move for this ladybug?

Ladybugs

Late ladybugs were left in start of winter.

They like white wall, do you know?

It was cold day and, they hid under edge of wall, among leaves of pine.
