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.

Dingy White Plume Merrifieldia baliodactylus

Wingspan c.20-27 mm.

This species is distributed mainly in the southern counties of England, but also occurs locally in some of the northern English counties.

It frequents hillsides and waste ground generally on calcareous soils, flying in a single generation in July and August.

The larvae feed on wild marjoram (Origanum vulgare) in spring, biting through the stem and causing the upper leaves to wilt.
