Distinct paucity of butterflies this year, and mostly cabbage whites where there are any. Bees don't seem too diminished. In this last week we've had three 2" hornets in the house. They're dead easy to get out, though: open a window, wave something like a newspaper in their vicinity, and off they go.
ETA: just been checking: in 2010 I wrote a piece about the sudden decline in pollinators visiting our buddleia. We used to get swallowtails, FFS.
