When was the black-veined white butterfly last seen in England?

The year 1925 was when the black-veined white butterfly (Aporia crataegi) last was seen in England.

Specifically, Europe, North Africa and temperate parts of Asia such as Japan and Korea are places in the world where the striking butterfly can be found. But the range is becoming increasingly threatened and limited, particularly in Europe. In fact, the butterfly no longer can be found in northern European countries.
