Please note that the NBN Gateway map service has been terminated as of 1 April 2017.

As soon as a replacement map service is available, distribution maps will hopefully appear here again.

In the meantime, you can get some idea of distribution from the NBN Atlas website.

Pearly Underwing Peridroma saucia

(Hübner, [1808])


Wingspan 45-56 mm.

A migrant species in Britain, varying in numbers, but usually coinciding with arrivals of other European migrants.

It can occur almost anywhere in Britain, but is generally more common in the south, and though most frequent in September and October, has appeared in all months.

The upperwing is quite variable, and the hindwings are semi-translucent, giving the appearance of a pearly sheen.

The larvae are not usually found in Britain, but are believed to feed on a number of herbaceous plants.
