Grey pug
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.

Description
The forewings of this species are grey (occasionally with an ochreous tinge) marked with pale fascia and radial lines which give it a mottled appearance. There is a pale sub-marginal line and a small discal spot. The hindwings are much paler and plainer also with a small black discal spot.[2] Melanism is quite common in this species. The wingspan is 17–21 mm. See also Prout [3]
Final instar larvae are smooth and elongated. They are grey-green or red-brown coloured and show a grey-green to dark olive-green diamond-like pattern on the back. The side edges are whitish.The pupa is yellow-brown with greenish wing sheaths. At the cremaster there are six hook bristles, the middle pair of which is more powerfully formed.

The adults fly in May and June with a second brood sometimes emerging in August. The species flies at night and is attracted to light.
