I think we are fighting a losing battle now. It's not just the run of bad weather it is the lack of insects and their larvae.
If it's insects you want, come to my garden - I've come in from a half hour's tidying up (mainly brambles and stickyweed) and saw plenty of insects, including (rather puzzlingly) several bumble bees in the large hazel tree. No idea what they were doing with it, but they seemed obsessed: I saw at least four at a time crawling over the leaves, and by the buzzing sound overhead and behind me there were more in the tree.
There were also plenty of other insects flying around, I disturbed clouds of them as I pushed through the longer grass... and ended up with "spit" on my trousers, which I think is from a froghopper.
This is still relatively early in the day, I expect the hoverflies and more will appear later on.
The first clovers are now opening on the lawn (which seems to have acquired buttercups from somewhere too), and the fuchsia is now well in bloom. No bees on them, though, which is unusual. I still don't know why the bumble bees (with brilliant white tails) were so fascinated with the hazel leaves though!
