Having not seen two of this genus closer to each other than a hundred yards, there were 5 in this short 50 yard stretch, with a pair, one quite small, together on a small plant. No net, this sat still as the small tube was popped over it, so it could be checked. Not suspect in any way it was then released.

So far I've only found this species in urban parks. As usual there were several Ectemnius Digger wasps about, I can only really tell the difference if they fly close to the ground or close enough to see the wasp's big square head. Very low down the wasp bobs more in it's flight or might lurch suddenly and the fly hover-drifts more. Plus the fly will wander off into the grass while Ectemnius seems to stay closer to its log haunts. Once settled all similarities are gone.
