The adults emit a squeak when alarmed, made by expelling air through its proboscis (tongue), which has a structure that vibrates like the reed of a wind instrument. The species is nocturnal, only usually seen in light traps and sometimes in bee hives in search of honey.
The caterpillars are also very large; in a good immigration year it can be seen in potato fields, pupating underground from August to October (although the moth is unable to survive winters in the UK).
