I think I see an insect silhouette; maybe an ant. I wonder why there is black in some holes? Interesting photo from a nature and a pictorial standpoint.
@rvwalker It's really quite interesting that the Cherry Tree provided so much food while in bud, bloom, post bloom, and now in falling leaves. I believe the black is where the leaf is rotting out from some bug infestation while it eats the leaves. All I know is that I have never been more observant of a tree than this year!
@juliedduncan LOL!
