I apologize now for the quality of this picture! View of the "Communal"? Sphecid mass inhabiting the gap between a fence pole and a piece of bark.

These are podalonia males roosting together for the night. You can tell podalonia from ammophila becuse podalonia have a hairy thorax and ammophila dont.

a "sleeping aggregation" of male Podalonia?

Yes, these are Podalonia males.

I never knew!
I didn't know that Podalonia did this, too. Are such sleeping aggregations widespread in the Sphecidae, then?
