Cluster fly - Pollenia

Cluster fly - Pollenia
Fullerton Arboretum, Fullerton, Orange County, California, USA

I usually associate these with spring, and this is the latest in the year I've seen them. This one is in good shape, so it doesn't appear to be a "leftover". (Last sentence is incorrect; see comments below.)

Maybe the Spring ones
are the "leftovers" !! Where do you think the Spring ones come from?
Out here in the east the adults emerge in the Fall and overwinter to re-appear, like magic, in the Spring.

Good to know.
The first time I had one IDed, the person commented on the fly's "coat" being thicker in the spring and flies looking fresher then. On that I based my wrong assumption.
