Busy flower beetles

Being rather seriously short-sighted, I've discovered new delights in the garden by just leaving my specs behind. A whole world of tiny insects is thus revealed and I can find new things to photograph...as long as I don't trip and fall with my limited personal depth of field. I was in London all day so went on a spectacles-free stroll when I returned. The most numerous and busiest group of insects were these flower beetles - genus Olibrus I think - harvesting and processing pollen like an army of tiny fruit pickers. They are only about 1.5 mm long so I need better camera gear to get any better shots.
