for the last month something has been cutting out parts of the leaves of my rose (see picture), chillis and a few other plants - I imagine it is some type of leaf cutter which can fly? Any tips on how to reduce the incidence would be much appreciated

I live on the 3rd floor of an apartment in central Budapest, Hungary - the weather is currently 77F, district is almost devoid of greenery!
