In the garden

The garden's overdue for some proper attention and I made a gentle start today. 
Continuing yesterday's passionflower theme, this morning I got absorbed in watching this hoverfly on one of the remaining blossoms (correct ID, I hope? I'm no expert). Watching it through the lens, quite high up against the wall, I was able to see its careful movements and - I think - a tongue protruding at intervals.
Later I pruned the damson tree. It felt a bit like doing a haircut for a friend who hates haircuts, though I did get rewarded with a bowlful of previously-invisible fruit - the last of the crop, ripened to real sweetness in the sunshine.  
Ideally I should have done this earlier in the summer, but I hadn't wanted to disturb the tree while it was full of fruit.  Gardening writer Monty Don describes damsons as "scrubby, untidy trees": they tend to produce a tangle of twisting, twiggy growth. His advice is to keep pruning to a minimum and to let both plums and damsons "sort themselves out" vis a vis the various pests to which they're liable. "Damsons simply take no notice" (of the pests), he comments. 
All this is advice after my own heart. 
I cut out the most obvious crossing or dead branches, lopped off the one that's been overhanging the school playground next door and crossed my fingers for plenty of delicate blossom and a good crop next year.
