Silver-ground Carpet - K.Noble

The Silver-ground Carpet (Xanthorhoe montanata) is a moth of the family Geometridae. It is common throughout the Palearctic region, the Near East and North Africa.

The wingspan is 29-33 mm although some northern races may be smaller. The forewings are white with a broad shaded band which varies from pale grey to almost black. The hindwings are also white with pale fascia and a small black discal spot. The species flies from May to July , usually at dusk. It will come to light but is not strongly attracted.

The larva is grey with a purplish-brown back. It has been recorded feeding on bedstraw, Corydalis, globeflower, hemlock and primrose and probably feeds on other low-growing plants. The species overwinters as a larva. The flight season refers to the British Isles. This may vary in other parts of the range.
