I have planted some of the Kale seedling into the flower beds. It is, or, better be said was 'cavolo nero', the black Tuscany kale. It is really attractive plant with dark green foliage. Yesterday afternoon I noticed that all of them have been eaten by these tiny bugs on the photo.
I have no idea what it is. Looks like a stinkbug to me. Google research hit only one result. The photo matches my bug, but the author himself does not know its name. Anyone?
