Scientific name: Xanthorhoe fluctuata
April to October. Britain and Ireland. Small to medium-sized, grey-white, with a distinct dark patch on the forewing. Found particularly in gardens, allotments and on rough ground.
This moth can resemble the Galium Carpet, which has more pointed forewings and more distinct white areas between darker forewing bands. Darker forms of the moth found in the Northern Isles, northern Scotland and urban parts of London resemble the Striped Twin-spot Carpet, but the dark band on the forewings is darker on the leading half in the Garden Carpet.
The adults can be found at rest on walls and fences during the day and is readily disturbed. They fly from dusk. The larvae can be seen from June to late October or November and overwinter as pupae.
