Wow
This is a neat shot. I don't know what it is, though.

 
Looks like a female Megarhyssa
and at least 4 males, with one of them successfully mating. See and

Nice photos, and thanks the both of you. I have many more of this species from today's shoot, several in which the female is laying eggs. From what I have read, dead logs are one of the most common places that this species lays eggs. That's exactly where I discovered these wasps ~ dead logs.

 
We hope one of the experts will chime
in with an answer, but we don't think she cares about the log at all. With that long ovipositor she is probably drilling down into the wood looking for a horntail larva, according to the info page, upon which to lay her egg. We'll check the comments on the images in the guide and see what we can find. So the real question is what do the Horntails like!
