    Even covering the area they were growing with paving hasn’t stopped them resurfacing all over again!

    Whenever I find a vertical tear in the tender new stems of roses, I cut them off and that is the only way I've found to avoid these sawfly caterpillars. I do not spray mine. There must be an easier way though; if anyone knows, please share.

    And dances with the daffodils (roses). Taking a bit of liberty with Wordsworth :)

    I have sparrows nesting and I think they help a lot with the sawfly. I do some night hunts and cut off worst affected leaves - that's where I usually find the grubs.

    @Eustace, I usually find those vertical wounds after the eggs have hatched! I seem to spend my life picking off the slugs, I don’t think I have a rose without them, so lucky you @peteS that they seem to focus on just one! Boscobel looks fabulous. Spraying doesn’t really work anyway as you have to spray the whole of the underside of the leaves, stems and canes and that’s an impossible task if you have lots of roses.

    I have three different types though, the curled rose slug are the worst, they devour the whole leaf - stock photo for illustration purposes, just pray these don’t make it to your garden:
