Allantus basalis

Allantus basalis is a species with a northerly distribution in Britain. The British subspecies Allantus basalis caledonicus may in fact be a separate species from Allantus basalis basalis. Both forms have been found in Scotland. The abdomen is black with a pale off-white to yellow girdle on the tergites. The hind femora are black. The labrum, palps and front trochanters are also yelowish-white. Coxae are for the most part black. In subsp. caledonicus, the apices of the hind tibia and tarsus are reddish-brown and in subsp. basalis they are black.

Larvae feed on roses.
