More iridescent than the eighties these beetles, coleoptera I guess as they look more beetle than bug were swarming out of one tree, across a picnic bench and onto another tree in a beachside Balmoral park last week. Each a ambulatory study of scarab-esque they appear to be either laying these eggs, or perhaps eating some thing else's.Or perahps they are grazing on the just discernable fine film of lichen.
