Strange clustering -
are they settling in for the night? Or ... ???

 
:)
I guess it's not too strange in certain circumstances. There is a large field of weeds growing next door to my yard due to the slow construction process of a new house that's being built. Along with the weeds, there is a growing number of insects. Thread-waisted wasps are among the array of insects that I'm seeing, and in large groups. In fact, there were around a good 12 of them on one set of weeds - no exaggeration. It was nearing dusk at the time this photo was taken; however, I have also seen this species in the same area during broad daylight. So, in these circumstances, I do find that the time of day with this species is unimportant compared to the fact that natural habitat (the woods) has been torn down and there is a huge growth in the building of new homes.

 
Ammophila
Often choose grassy sites and stem perches for the sleeping positions at night. It means there is a nearby nesting colony in most cases. But they do cluster in their sleep areas. And the sleep periods are not always strictly evening and dusk.
