help...leaves have brown spots and look eaten

[nakita19_98]

:bang: the leaves on 2 of my trees have brown spots and look eaten. one tree is a flowering pear tree, but not have as much as the other. I do not know what kind of tree this is. I did notice when I was watering them that a lot of pill bugs started coming up from the ground. can this be the source of the problem or could there be something else? :bang:

Pictures are really needed to even begin to give you an educated guess.
