It kept hovering around me so I put my finger up to it in the air and it landed on it.

I think Bill's got it right, in retrospect - I identified this fly once it was in Dasysyrphus, but completely missed the eye and wing vein characters!

I *think* one of D. pacificus or D. pauxillus, using the new Locke and Skevington key (Zootaxa 3660, 2013).

The maculae on tergites 3-4 don't reach the edge of the abdomen (very easy to tell with your sideways shot, thanks!). I can't quite see the gena to see if it's light or dark, but the markings on the abdomen don't match creper (not arcuate with flattened edge), and markings and range don't match richardi or lotus. The markings aren't constricted, and the range and appearance match neither laticaudus (similar appearance, but an eastern species) or nigricornis.

The problem is that pacificus and pauxillus are apparently very hard to tell apart in sympatry, aka southern BC and most probably WA as well. Bummer! pacificus apparently has more bare wings, but I'm bad at judging those and the authors advise caution and prefer genital dissection.

Nice fly!
