Would you know it if a bat bit your shoulder?

Would you know it if a bat bit your shoulder?
I was out and in the middle of the day around 11:30am.
I walked past a small tree around 6ft tall.
I felt something poke me in the shoulder, but I'm not sure if it was a bat or just a tree branch>
Didn't notice any redness, or bit marks.
But it does say sometimes bat marks aren't noticable.
