Yellow and Black Hymenopteran - Pseudomasaris zonalis - male

Yellow and Black Hymenopteran - Pseudomasaris zonalis - Male
Sunrise Ridge Trail, Olympic National Park, Clallam County, Washington, USA
July 18, 2013
Size: about 13 mm
Even with my naked eye, I thought "sawfly," but the thorax is patterned and not sculptured, the wings look waspish, and some wasps have clubbed antennae.
I only got a few shots from directly above, and then it flitted away. It had landed in the middle of the trail.
The elevation is about 5150 feet, on a ridge.

Here's a photo that looks similar, but with an obviously different color pattern:



Ooh, here's a better match:

Nice find -
extends our photos to the Olympics. As long as some Phacelia are in bloom you should also find some females.
Moved from Pseudomasaris.

Phacelia
Yes, Phacelia is in bloom. I've photographed it many times but have never seen this species. We're having a long blooming season this year, so I'll keep my eye peeled for Pseudomasaris.

With a bit of patience
you should see the females at Phacelia flowers, especially P. hastata & P. heterophylla.

Moved for expert attention
Moved from Pollen Wasps.

Sorry for the (inadvertent) double move.
