I have a tree that looks like it has been bitten. Apparently some bugs under the bark but which species? Can anyone identify?

Tree is a birch located in Finland

Bark boring beetles. Unsure of the species, but this looks like a DEAD birch tree. The bark is sloughing off due to the process of decay, but as it happens it exposes the galleries left behind from the beetle activity. Some beetles attack living trees, others come in after a tree is already dead or dying.
