Thanks John. You are probably right about that, just hatched. I am also told the females boot the males out of the nest asap - they probably have a short life span. I had lined my garden with all sorts of material for bees to use, including much pith centred stems from old dead plants that naturally hollowed out as they dried, bunches in the passion-fruit vine and elsewhere. But was unable to locate the nest of these bees.
Territoriality makes sense and they did return to the same leaves for a few weeks, never found them on any flowers though.
Always a pleasure to view your work Mark -love your light and composition!
I've seen this before, and I think that you found them shortly after they hatched. Very common for them to sleep bunched up like that, but after a few days they will separate and stake out flowers to lay claim to -drive off other males and wait for females to be attracted to the flowers.
I have a similar species here that likes to sleep inside large flowers.
