Myopa vicaria? - Myopa vicaria

I'm wary of posting this at the species level, but it's a good match with what's posted here, and the dark spotting on the wings seems to rule seems to rule out M. clausa, which looks like the other expected species. Basking and visiting flowers on American holly in our yard on Martha's Vineyard island. Would welcome confirmation or correction!

Dark spots
According to the revision by Camras (1953), only Myopa vicaria has dark patches over crossveins and not elsewhere. Other species have clear wings, spotted wings (willistoni), or dark wings with clear patches (two Mexican species).

Thanks, John.
