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.

Dichrorampha sequana

(Hübner, [1799])

Wingspan c.10mm.

Occurring fairly locally in the southern counties, ranging to the Midlands and Wales, this is one of the smaller Dicrorampha species, and can be distinguished by the broadly rectangular cream-coloured dorsal blotch.

It prefers unkept verges and embankments, where yarrow is common, and flies in the afternoon and towards dusk. Adults are on the wing in June, and rest on the flowers of the foodplants.

The larvae, rather like other Dichrorampha species, feed internally in the rootstocks of the foodplant, yarrow (Achillea millefolium).
