There have been very, very few butterflies about this summer. I’ve not seen any of this species: a meadow brown.
I have seen a handful of cabbage whites, with clear enough views to spot that there have been both large whites and small whites. There have been a couple of blues, too far away for a definite ID, but almost certainly holly blues. All of these in much smaller numbers than usual, and that is it.
ADDITION: I drafted this a week or so ago. Since then it’s actually been hot and dry. I’ve seen a few more butterflies, including fleeting views of one, maybe two, meadow browns.
