Buckinghamshire, United Kingdom

I've just noticed that the leaves of my hardy geranium 'rozanne' are peppered with tiny holes (about the size of pin heads) does anyone know what they can be? The plant doesn't seem to be suffering in any other way, it's flowering really well. I am growing it in a pot and this is its first year. Thank you
Having had a further look at the leaves I can now see lots of tiny caterpillars on the underside of them - so now we know who the culprits are! So now to try to get rid of them.......
