Moths the size of a normal human hand are making their way to the United kingdom and Europe.
Wildlife and bug lovers have been encouraged to look out for the migration of rare moths that are on their way from overseas.
There are various breeds making their way to shore and those who spot them have been encouraged to report any sightings to their local conservationists.
Among the rare moth breeds is the silver-striped hawk moth, the hummingbird hawk moth and the giant convolvulus hawk moth - whose wingspan spreads to more than 10 centimetres.
According to the Butterfly Conservation, you can find these moths near plants of ivy as they feed on the blossoms which flower late in the year.
Speaking to The Mirror, Richard Fox, who's head of recording for the Butterfly Conservation said:
A quick check of ivy blossom on a sunny autumn day will reveal bees, hoverflies, butterflies and other insects, all making the most of this seasonal bonanza of nectar.
After dark, the pollinator nightshift takes place and a myriad of moths come out to feed.
For this year’s Moth Night, find some big patches of ivy flowers nearby and go back with a torch after the sun has set.
It’s a fantastic and easy way to see some of the beautiful moths that are on the wing in autumn
Coincidentally Moth Night will be taking place this month (12th-14th October) and will include moth trapping events across the UK.
