Ancistrocerus parietinus I believe my other wasp to be, it was here the day before the other one.

There are several matches, some of the yellow marks on images seem to vary slightly but are all in the right places.

Interestingly the next image shows only 3 stripes on the lower abdomen, which gives some clue that they may vary. My other wasp might be what we think it its!

Janet,
based on that first site you link to above, I would say that this wasp is Ancistrocerus trifasciatus, but that your other wasp: http://davesgarden.com/forums/fp.php?pid=3627798
is Ancistrocerus parietinus.
You ask about starting the family Eumenidae. This seems to be a confusing area, with almost equal use of Eumenidae as the family or Eumeninae as a sub-family of Vespidae.
We have a number of Mason Wasps in bugfiles already as Vespidae (sub-family Eumeninae), so I think we should stick to that, so perhaps you could add your two wasps as Vespidae,

Ken

Hi Ken, sorry for the confusing opening line, I meant this wasp when I said 'my other wasp'.

Thanks for the explanation of families, it's so confusing for the uninitiated.

I'm still not certain of their ID's, again you will have a better idea of what you are looking at where I am going just on the patterns. I had thought it might be the other way around as the wasp on this thread has 5 stripes on the lower abdomen.

I did find a site last night which I lost when AOL decided not to work and closed, then I couldn't remember what I used in the search to find it. It had several pics of Ancistrocerus parietinus which looked very much like this one but had 4 stripes.

I found another site which has a pic of the male of Ancistrocerus parietum which has 5 stripes, a slightly different 'waist band', and no thorax spots.

The differences in male and female are not well documented but I did find another, Ancistrocerus gazella which was menitoned along with Ancistrocerus parietinus on the site I lost as being the two most common. A search revealed pics of on a NZ site and CA site. The female has 2 thorax spots, male has none. It doesn't match mine either, A gazella has an extra yellow bar under the spots on the thorax.

There is a pic of another with two lower abdomen stripes, Ancistrocerus antilope on a German site, middle pic on the left. The thumbnail is the only way to get a name on the top bar before you open the site.

I saw a wasp with several stripes land briefly today, so I think I will hang fire for a while and see if I can get more pics. There are so many that look alike I would hate to get it wrong.
