Leaf cutters

Somethingis eating chunks out of the leaves of my rose bushes, laurel bushes and holly trees. There are no signs of caterpillars or other bugs. Does anyone have any idea as to what it might be and how to get rid of the problem?

If the holes are V shaped on the edge of the leaf they are probably Vine Weevil adults, who come out at night. If they are watch out for root damage later to crops nearye. There is a biological control that works very well and is absolutely safe to use called Nemasys. Probably other Trade names as well.

Are the holes semicircular and on the outer edge of the leaf, if so then it is probably a Leafcutter bee. There is a pic of one in my pics.
