Kay, if you think that these two are the same female, then you should keep them linked, but if you are not sure, then keeping them separated is the best way go.
Thanks for the quick response!

Hemipepsis ustulata
Yes, they are the same female: photos taken only seconds apart. I really appreciate your help!

Kay, that's great, here's what to do with her:

Thanks again!

A tip
Try to find where they're feeding. It took me several days to get good shots my first time out. I finally found them feeding and mating on large patches of buckwheat. It still wasn't easy.

It's often very tough to get IDs on these. A good, clear shot of the wing veins is important, but you already know that. (BTW, same goes for most flies.) And as you've seen, knowing size can be crucial. (Personally, I'm just awful at that.)

Good hunting! You'll get 'em - it just takes time and patience.

Spider Wasp
Thanks, Ron. I hope they'll be around for a while. As soon as my house guests leave, I'll start looking for buckwheat!

I think you mean between 30 and 40 mm, 30-40 cm would make the wasp 12-16 inches:)

I believe this is Hemipepsis, judging from the lack of bluish reflection and I think I can see enough of the wing venation in this shot to make the ID.

Thanks, I've just changed cm to mm! khl
