Spider wasp? - Camponotus

Spider wasp? - Camponotus
Mount Saint Helens, Skamania County, Washington, USA
May 2, 2014
Size: Body length 20-25mm
Photographed near 7500 ft elevation at 1pm during a ski descent of the west slope of Mount Saint Helens in the Cascade Range. This is above Blue Lake trailhead, and far above snowline which was at about 3800 ft on this day. Also photographed an identical-looking insect near 6500 ft elevation around 10:30am while ascending a different part of the slope about 1/2 mile north, most likely a different specimen. Both were slowly walking across the snow surface. At the time, I was guessing that they might be spider wasps (Calopompilus pyrrhomelas?) based on size and location, but on closer inspection of the images the wing, head, antennae appear quite different from that.

Spider wasp? - Camponotus Spider wasp? - Camponotus


A queen carpenter ant. Image is too dark to tell which, but the choices in the location mentioned are limited to C*modoc and C*herculeanus.

Should this be left at genus level? C. chromaiodes does not occur in Washington.

Moved for expert attention.
Moved from ID Request.

Alate (winged) ant. The experts will tell you what kind.
