Lots of other insects such as the Cosmopepla bug on Figwort, which seems to be a particular favourite of theirs. In fact, I spent about 40 minutes hanging out next to a big patch of figwort just below the FWG near the Mallow Bank. There were many different species of Syrphids, the above Cosmopepla, bumblebees, vespid wasps, bald-faced hornets, etc.
