Davey, P., 2009: A species occurring across England and Wales, but very local in Scotland, the larva feeding on the flowers of many plants including mugwort (Artemisia vulgaris). In Dorset, the moth is at very low density, and at most noted only a handful of times in a single year from any one locality. This may be because mugwort is a fairly local and thinly spread plant, growing in roadside verges, urban wasteland and tips, but rarely in permanent, native habitats.

The moth is rather similar to the Shaded Pug1840: diagnostics include: 'lighthouse' effect of white colouration on thorax and central portion of forewing; dark abdomen.
