Dryadaula pactolia

Meyrick, 1902

---

Wingspan c.8-11 mm.

A rather rare and unusual species that is only found in the British Isles occasionally. Its larvae feed on a fungus Rhacodium cellare, found in wine cellars and distillieries.

The illustrations here are of individuals from a house in Dundalk, Co. Louth, where large numbers appeared in 2010/11.

The adult moths can appear any time between March and November, presumably being continuously brooded indoors.
