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.

Single-dotted Wave Idaea dimidiata

(Hufnagel, 1767)


Wingspan 13-18 mm.

A rather pretty species which is found mainly in damp locations such as marshy woodland, fens and river banks.

Generally common throughout Britain, apart from Scotland, where it only occurs in the south.

Flying from June to August, the adult moths can be attracted to light.

The larvae feed from Autumn through the winter on cow parsley (Anthriscus) and burnet saxifrage (Pimpinella).
