Mecyna asinalis: Distribution map

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.

Mecyna asinalis

(Hübner, [1819])


Wingspan 25-29 mm.

This subtly attractive Pyralid, sometimes known as the Madder Pearl, is scarcely distributed mainly around the coasts of south-west England, Wales and Ireland.

The adults can be found on the wing between May and October, probably in two generations.

The larvae graze on the lower surface of the leaves of wild madder ( Rubia peregrina), removing the epidermis to leave a distinctive feeding pattern.
