There are few species among the hawk-moths that can rival this charismatic insect. This is a big moth, capable of migrating long distances. It is a rare vagrant to Britain from Southern Europe, where there are established colonies. The species inhabits dry river beds, oases, and warm southern hillsides where the foodplant grows. The striking caterpillars feed on the leaves and flowers of Oleander. It rests during the day, usually suspended among foliage or the trunks of trees. The adults have a preference for Petunia or the Nicotiana flowers. The moth has been recorded in Britain a number of times!
The larva of the moth is also impressive and when fully-grown can reach sizes of 8.5 centimeters. Some adult females can also attain a wingspan of 12 centimeters.
