Weird UFO found on picture caught on May 2018

A witness discovered an incredible UFO in background of picture caught on May 9, 2018, in Ohio. This object made no sound.

Witness statement:

I was playing outside in my yard with my son. He had my phone and was taking pictures. I didn't actually see anything until I saw the picture. There was no sound that drew attention or anything. Looking at the original picture I thought it was a spider on the clothesline, so I zoomed in. Thought it was odd, and joked about it being a UFO, one of my friends directed me here.
