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.

The Rivulet Perizoma affinitata

(Stephens, 1831)


Wingspan 24-30 mm.

A widely distributed species in Britain, but local in northern Scotland and Ireland, occupying woodland margins, hedgerows and grassy embankments.

The main flight period is between May and July, when it is often attracted to light.

Red campion (Silene dioica) is the preferred foodplant, the caterpillars living inside the seed capsules, eating the seeds.
