Hello!
Is this a meat spot or parasite?!
I read oviduct fluke is not very common but I can't stop thinking that's what it is...
We are in northern United States.

Thank you!!
I think I looked at it too long and convinced myself it looked like it was moving.

Spots can do that, especially if they're on your ceiling and your trying to decide if it's a spider...
