Chrysidid wasp - Parnopes edwardsii - male

Chrysidid wasp - Parnopes edwardsii - Male
Marin County, California, USA
June 21, 2010
Size: 11 mm body length
It was the same blue-violet color when it was alive.

ID confirmed by L.S. Kimsey

Really?
All the specimens of this species I've seen (from Oregon, though) have been much more green. Further, I have definitely had some chrysidid specimens change color after death. Maybe they get greasy and it changes the reflective properties?

 
I think...
I read on here that the species comes in two color variations, the greenish kind and the more violet kind. I took this photo right after I pinned it, within an hour or so of removing it from the freezer, and the color is exactly the same as when it was alive. I didn't even know it was a Chrysidid wasp until I actually got it into a vial, since the bright sunlight made it look a blue-black color with no hint of green as it moved from flower to flower... The long mouthparts and the fact that its face was stained yellow from pollen had me thinking it was some weird bee for a while, hahaha.

Kimsey (1) states that this species can have "bright green, blue or purple coloration".

sweet
good thing, those colors [like hummingbird's, &c] are produced by 3D integument structure and thus don't fade -- unlike those for which pigments are responsible, often chemically unstable and prone to fast decay
