We have a number of introduced species of trees and shrubs in the gardens and parks near here. For example arbutus, fig, gingko, holm oak and a couple I have photos of but don’t know their names.
What sort of insects might I find on these, so far I’ve only seen flies (bluebottles) and possibly a few hoverflies.
The first is Arbutus (strawberry bush?) the other two I know by sight but not their names.
