So Martin, do we finally have another Nausigaster? - Nausigaster - Female
Santiago Oaks Regional Park, Orange, Orange County, California, USA

I think so, and it appears to be a bit different than the two from last year. I'm talking serious eyes here! (May just be my newer lens and camera.)

This fly was quite hard to photograph - wouldn't stay put - and it was on the other side of some nasty cacti. Will try for a return engagement, hopefully soon.

Hmmmmm... I still think you h
Hmmmmm... I still think you have the same species... I they all have a red scutellum (all the species in my collection don't - but I have seen specimens which are completely red all over the body), but the most important is the wing coloration. There are species which have much more brown on the wings (very common is a U-shaped marking on the front edge of the wing), yours just have the dark scutellar spot, whithout any crossveins darkend. Of course there are several species with the reduced marking - I am still waiting for a revision of this beautiful and hard to photograph genus, hopefully I could have a better idea about the species identification. So keep on hunting these beautiful flies...

Thanks, Martin!
I've been collecting this genus here in Tucson (fairly commonly), and didn't even know what family to start looking at:-)

I'm after them!
At this point, I can distinguish them in the air. (They look bluish to my aging eyes.) Now, if I can get them to pose...
