Wasps and Hornets

Please help Identify a bug that we saw at our home in Rocklin, California (Sacramento area) today. It was about 2" long, blue metallic looking – looked like some kind of huge wasp or hornet that that was carrying a huge dead cricket. It flew also. My husband has spotted about 10 over the last few weeks around our yard. I’d like to know what it is, to know if it can sting my kids. If you have any ideas, we would be eager to know what this is.
Thanks a lot,
Mary

Dear Mary,
It’s Probably a Blue Mud Wasp, Chalybion californicum, which generally preys upon spiders, but crickets will do. They can sting, but are not aggressive. They are solitary wasps that nest in abandoned Mud Dauber homes or simple crevasses.

Thank you so much. My 9 year old daughter was freaking out when we saw it – I don’t think it helped that it was carrying a huge cricket! I just looked up a picture on the web, and it sure looks like what we saw. Thank you "Bugman".
