Hemipepsis ustulata - male

Hemipepsis ustulata - Male
Oakland, Claremont Canyon, Alameda County, California, USA
July 20, 2008
Size: 1"
I've seen several of these in the last couple of days - none resting long enough for me to get a better picture.

Male! - Please unlink the female(s)!
Kay, I think that you confused the scientists, by adding(linking) those two images of the female(s). Please unlink them from this wasp, which looks like a male wasp to me. Thanks
Also, the other images do not have sighting dates. If you filmed them(her) on the same day as this wasp then you can use this date, but if it was the next day...seven years ago, wow.
Well, if you can't remember, then just use this date or the next day if that is more likely. Good Luck!

 
Hemipepsis ustulata
Thanks Bob. I've unlinked the images, adjusted the gender for the male and changed the date on the females ... in Bugguide and in my photo files and home website. Right now the females are not showing up in the BG Images; they should be linked to each other. ??? ... Kay

Spider Wasp?!?
Perhaps Pepsis thisbe. Must get a better photo.

Pepsis or Hemipepsis
...

 
Not a Cryptocheilus?
The size seems a tad small for either of the tarantula hawk genera....

 
Probably
Oops, I didn't note the size the first time:) However, the shape on first impression reminded me more of either of those two genera and size in the field is easily misjudged. It could also be one of the orange-winged Entypus as well (some E. u. californicus are exceptionally small). In any case it'll probably go identified, if it doesn't go into frass.

 
Beetle? Wasp?
Am hoping to go out today and find another to photograph. I expect this one to be frassed - it just doesn't show enough to help anybody!

 
Oh, it's a spider wasp...
in the subfamily Pepsinae, probably either Cryptocheilus or Entypus. It seems to be male, so if it is actually bigger than 1 inch it could possibly be a Pepsis or Hemipepsis but that is highly unlikely. If you had a shot of the wings that showed venation we could narrow it down a little. If it is narrowed down to Entypus or Cryptocheilus it is highly unlikely that we'll be able to separate the two from only a photo. Just as a note, it is not Entypus unifasciatus californicus, that species has orange antennae.

 
Spider Wasp
Okay, thanks Nick.

 
Hemipepsis ustulata, female.
That would be my diagnosis now, with the added images and the change in the size. No bluish reflections pretty much rules out Pepsis. Let's see if Nick agrees.

 
Hemipepsis ustulata, female
Thanks, Eric ... for the identification, and for your willingness to keep at it!

 
I agree...
I identified it to genus only at first, but range and the black antennae make it H. ustulata.

 
Hemipepsis ustulata, female
Thanks, Nick ... for the confirming identification, and for your willingness to keep at it!

A wasp
Try Pompilidae.
