The lime-speck pug (Eupithecia centaureata) is a moth of the family Geometridae.

It is a common species throughout the Palearctic region (where it is found in Europe, Central Asia, Mongolia, southern Siberia, eastern China (Guangdong) and Taiwan[2]), the Near East and North Africa.

This is a distinctive species, all the wings being largely white except for a black blotch on the costa of the forewing.

(perhaps developed chiefly in Asia but also recorded from the Tyrol) the ground-colour of both wings has a smoky suffusion.

The moths fly at night and are attracted to light and nectar-rich flowers.
