The privet hawk-moth is the UK’s largest resident moth.
Adults are on the wing between June and July. They are strong fliers and range widely in search of mates.
Their caterpillars can be spotted from July to September. They pupate underground over the winter, emerging as adults the following summer.

Privet hawk-moths are common across southern and central England and Wales. They are regular visitors to suburban parks and gardens as well as woodland, hedgerows and the wider countryside.
Unlike butterflies which warm up by basking in the sun, most large moths ‘shiver’ to warm up their wing muscles for flight.
These moths feed by night but can sometimes be found resting on tree trunks during the day. They are attracted to light and are easiest to spot by using a moth trap.
One way to find their caterpillars is to look for their unusually-shaped droppings beneath likely feeding spots. They are small are dark, and said to resemble hand grenades.

The UK’s population is stable and not thought to be under threat, however the rapid spread of ash dieback disease could impact the abundance of suitable caterpillar foodplants on which to lay eggs. You can encourage these moths to visit your garden by planting strong-scented night flowers.
