Thanks so much for links, definitely not leaf roller though, no webbing,
but holes are spread out, and quite small and round at first, seasons
over now, but just keen to avoid same next year. ..bit puzzling though
as i found so few worm things, considering the damage they did! Thanks
for your help.

The pattern of damage always reminds me of tiny buckshot.

Look into predatory nematodes.
