Due to the very blurry nature of the object, vs. everything else in the photo, I would say it is extremely close to the camera lens. And I would guess it would be a bug. Since everything else is in focus, like the clouds, tree, etc., if it was far away, it would also be clear. If it was moving fast, but far away, you'd see a different effect with a "trail" at the back of it - also know as motion blur.
