Live twig (Geometridae caterpillar)

We found this living twig when we were picking blueberries in the forest.
At first I thought it was a blueberry stalk, but then it began to move.
Since I like to take photos and am not well versed in various types of insects, I am afraid to make mistakes when writing a species, because there are a lot of them. This caterpillar looks like Biston betularia.
Once we saw the same burgundy color in the garden.
We nevertheless accidentally brought several of these greens home with berries)). I had to let them go into the garden.
