These seven spot ladybirds have found a protected place to hibernate. 
I noticed these yesterday out walking. They hibernate in winter when there is no food source .
Temperature and day length trigger synchronous re-emergence in spring, in time for the arrival of food.
Ladybirds have to wait for unfurling leaves, and then for the aphids to get going too.
In Northern Europe temperatures above 12°C rouse the common seven pot ladybird.
It is very cold today it actually feels like winter so these ladybirds probably have a long wait until food !
