I was so sure this was a syrphid fly, but bugGuide has set me straight: it’s a Narcissus Bulb Fly Merodon equestris. At least it’s in the syrphid family.
And I do have actual syrphid flies, but they’re much smaller than Mr. Bumblebee Fakeout Merodon.
These two are Syrphid flies in genus Sphaerophoria.
