The grey pug (Eupithecia subfuscata) is a moth of the family Geometridae. It is found throughout the Palearctic region. It is also found in North America. Since it does not place any special demands on climatic conditions, special caterpillar food plants, geological subsoil or the like it is a typical species of almost any Hochstaudenflur (plant corridor), where it occurs in the herb layer, in bushes and even on deciduous trees. It can be found on forest edges and hedgerows, on heath, in rocky places and wetlands, parks and gardens, as well as in villages and town centres.
