A small squirrel of southern and central Finland that glides between trees on a membrane joining its front and hind legs.
It has pale gray fur and a small, slender body. A gliding membrane joins its front and hind legs, and its tail is flattened from above.
It eats leaves, buds, alder and birch catkins, ripening seeds, and green spruce cones. Adults tend to stay in the same area, while young animals may move away from where they grew up.
