Every segment of this moth's whitish abdomen carries a small pair of dark dots, a subtle feature easy to miss beside its bold, broad wing band.

The Silver-ground carpet has a wingspan of 29 to 33 mm, with white forewings crossed by a broad central band that ranges from pale grey to near black, and white hindwings marked with a faint pale line and a small dark spot.

A single generation flies each summer, and by day adults can be flushed from low vegetation in woodland clearings and hedgerows, while caterpillars feed at night on bedstraws and other low-growing plants.
