S. grossa. Adults often retain markings.

Not sure.
Might even be a juvenile S. grossa. I have a feeling that they lose some of the pale markings as they age....much like widows.

Well I'll leave it here (in genus) for now...
We certainly have a lot of S. grossa, but it's also possible we have other species, too. My photo that shows the markings more clearly turned out to be blurry, so I didn't post it.
