small bee getting nectar from a flower.
No interactions present.
But I'll have to have a think about what it is.
and the strategically placed bee means that we can't even use the floral formula - but I would guess at Oxalis corniculata. I think I see out of focus Oxalis leaves in the background, and the reflexed flower buds also matches.
The bee is a Halictid (Halictus or Lasioglossum) female
