As you all might know, this species hibernates as an adult (mostly females).
So it happens when temperature goes up a little, or when they are disturbed too much, they tend to be actif and one can see them in the middele of winter.
Several years ago I found an adult female crawling in the forest on 10 cm of snow, on first Christmas day!!
It was together with thousands of small Heteroptera (something like Lygaeidae), alive and also crawling on the snow.
A surrealistic experience!
