Every shrub in a short section of border is being eaten by something. I can find no culprits even at night with help of a torch. If a caterpillar I would expect the edges to be eaten first but this is rarely the case here. Any ideas?  Leaf damage by Alf Parker, on Flickr  Leaf damage by Alf Parker, on Flickr Alf |

I would be curious to know, too- something has decimated our hedge this year, and the damage looks very similar to yours.

I too have leaf damage like this, but it is on an Avacado that I am growing indoors. I suspected vine weevil so treated the plant. Vine weevil was introduced into the house by a plant which I bought at a garden centre, which I intended planting outside, but did not get around to for ages, when I went to do so found the lavae round the roots.

This does not look like typical Vine Weevil damage.
The Vine weevil is mainly nocturnal and chews on the leaf edges. The main threat from Vine Weevil is the larvae which attacks the roots of plants and if left unchecked will certainly kill the plant.
I think the holes have probably been made by Sawfly larvae, of which there are many types, or by a leaf cutter bee though they mainly attack the leaf edge.

I think the damage on ours is not quite the same as that on Alf's... must be two different types of bugs? The hedge is made up of two sorts of shrub- one has a large glossy leaf, and the other has a smaller leaf- not quite as glossy. The large leaves aren't being attacked- just the smaller variety. Here are two photos of the two types of shrubs...  01 Hedge by Wabi Gallery, on Flickr  02 Hedge by Wabi Gallery, on Flickr This photo shows the two of them together... so it's easy to see that one type of leaf is being eaten, but the other is left alone.  03 Hedge by Wabi Gallery, on Flickr and this is a close-up of one of the leaves. I'm not sure if the fine web showing there has anything to do with it or not... might just be a spider's web, because there isn't a lot of this on the leaves. I know little about the hedge... we're only renting, and the landlord is clueless about gardening. I'd say that the previous owner put them in.  04 Hedge by Wabi Gallery, on Flickr |

Rowanberry- you have glossy leaves of Cherry Laurel + the ones being attacked are Viburnum tinus + the culprit looks like that of Viburnum Beetle.

The shrubs under attack in my garden are Cornus alba and Hypericum calycinum. Two very different leaves but clearly both appetising to whatever is eating them. I think Harold is right and sawfly larvae is most likely culprit. Out with the torch again last night I did find a very thin, short(1cm), green larva which had fastened itself to the edge of one of the holes. Unfortunately it dropped off onto the ground when I tried to remove the leaf with it still attached and I couldn't find it again.
