Slugs and snails= a small wildlife pond, with frogs to keep the numbers down.

Leaf cutter bees= Its only a few leaves on your roses so I wouldnt worry as they are hugely beneficial.

Vine Weevil= Empty pots and kill the grubs/ use nemetodes(expensive) or some rolled up corregated cardboard, and hope the vine weevil hides in there where you can check it in the morning and then squish her.

Lily beetles= Pick off by hand and squash.

Caterpillars= If you want butterflies then keep them, or just pick or flick them off.

Thank you for your comments .I heard of the small widlife pond before,I may try that.I found few catterpillars so I doubt them the culprits.The leafcutter bees I wonder about that because I planted a seed mix of annuals to attract bees in the garden and it worked i had garden full of bees all summer.If its the bees I dont want to stop them visiting so i will have to put up with abit of leaf damage. thanks again
