The spotted clover is a migratory moth from southern Europe. After thirty years of absence (it was reported in 1958, 1955, 1954, 1953 and 1945) it was observed in Twello (Gelderland) in 1995 and now it has been seen again in Groningen. This is also the most northern discovery of this moth which is not able to survive the Dutch winter.
