Unusual pinepine
There is a pine in our forest park, the trunk of which was damaged by bark beetles. The pine, unfortunately dried up, but under the flown over bark there were traces of the moves of the bugs, which, on closer examination, look very interesting and unusual.
Like letters unknown to science. I offer you, my friends, to admire this picture created by nature.
