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 Campion Sideridis rivularis

(Fabricius, 1775)

Wingspan 27-30 mm.

Distributed widely over much of Britain, and fairly common in places, the species can closely resemble The Lychnis (H. bicruris), but tends to have the two forewing stigmata joined at the base. Fresh specimens usually also have a purplish suffusion.

It mainly flies in May and June, but in the south there is a second brood in August and September.

The caterpillars feed internally in the seed capsules of various campions (Silene) and catchfly (Lychnis).
