Striped Hawk-moth Hyles livornica
Wingspan 60-80 mm.
A scarce immigrant species, which occurs in small numbers in most years, mainly in the south.
Nowadays, most records are of adults attracted to light, but in good years, caterpillars can also be found, the progeny of earlier arrivals. They feed on low plants such as bedstraw (Galium) and dock (Rumex).
The species generally arrives between May and October.
