There are about 20 hawk-moths that you might come across in The British Isles, some far more often than others. Some are day-flying (diurnal), some night-flying (nocturnal), some drawn to light others preferring sweet nectar. These moths sit in the Sphingidae grouping, and are more generally known as Sphinx moths elsewhere.
The photos above are the eight hawk-moths we have seen in our garden over the last three years of mothing here. So, still plenty to “tick”, as it were.
