Western Cicada Killer? - Sphecius grandis

Western Cicada Killer? - Sphecius grandis
Bear River MBR, Box Elder County, Utah, USA
July 12, 2009
These are the largest wasps I have ever seen. When I first spotted them flying I thought they were hummingbird moths. Are they cicada killers?

I emailed Chuck...
I emailed Chuck Holliday and this is what he said:

"The wasps you photographed were males - the females are even bigger.

Your photos are important to us because we've only seen this coloration in Big Bend Texas. The wasps are a variant color scheme of Sphecius grandis, the western CK."

So, I'm moving these two Western Cicada Killer.

Yes.
Nice shots! Can't tell you which species, as this looks like an exact cross between the eastern species and S. grandis. I'd write to Chuck Holliday and make sure he sees these images, if he doesn't want to run out your way and see the wasps themselves.

 
Okay.
Thanks, Eric. I'll email Chuck.
