Conservationists in England are asking people to record sightings of the palm-sized moth.
The moths migrates from southern Europe to Britain in early autumn, but they have already been sighted widely across the UK, and a record number is expected to migrate to the UK this year.
The Convolvulus is one of the largest moths in Europe and it drinks nectar from tobacco plant flowers. It also drinks wine.
Richard Fox, the head of recording at Butterfly Conservation, said it has already been a great year for moth immigration, and this type of activity usually peaks in early autumn.
Fox said that with such migrants like the Convolvulus Hawk mixing with home-grown autumnal species, Moth Night is a good opportunity for people to discover the wonders of nocturnal wildlife at a public event or even in people’s own back yards.
Moth Night runs from September 10 to September 12, and the theme is migration.
Asides from the Convolvulus Hawk-moth, there are 40 other species of immigrant moths that have been spotted in the UK for the first time in years, and this includes the Flame Brocade and the Black-Spotted Chestnut.
