You can't see much, but it is a picture of a hole with an acorn inside. The tree was like a type of palm tree and it was filled with plenty of other holes exactly like this one.
The insect or bug, was black and orange. It seemed to have been eating or jus relaxing on the leaf, it didn't move much.
On the side walk by a rollie pollie.
The bug was black and was laying on some type of foamy substance. Other plants were surrounding it with the same type of foam. The bug appeared to be some type of beetle.
