I'm pretty sure this is Toxomerus occidentalis. Can someone confirm?

I'm about 90% sure you're right, Kevin
This is the first incomplete pattern I've seen that suggests T. occi*dentalis. Such patterns aren't uncommon on T. margin*atus, but in those cases the pattern is very light, as opposed to the very dark color on this one. Interesting!

incomplete patterns
I know what you mean, Ron. If T. occi*dentalis didn't have such a unique pattern, I wouldn't have even guessed at this...

I'll be curious to hear what some of the fly/syrphid folks say.

After a second look, I'm sure it's T. occidentalis
