The distribution of Ceropales maculata seems to have a south-western bias with former strongholds in Cornwall, Devon and Dorset, although there are no records for the east Devon heaths (perhaps due to a low level of recording). Outside this area it is found along the west coast with scattered records inland. Recent Scottish records are from the shores of the Firth of Clyde and the Moray Firth; the Speyside records are all pre-1951. In Ireland the species is widespread, with a largely coastal distribution. Ceropales maculata appears to have undergone a dramatic decline during the second half of this century in many areas, although the Welsh populations still seem to be strong.
It is widely distributed across the Palaearctic from Europe and North Africa eastwards to Japan.
