Red Twin-spot Carpet Xanthorhoe spadicearia
([Denis & Schiffermüller], 1775)
Wingspan 24-27 mm.
Found fairly commonly throughout most of Britain, this species has two generations in the south; May to June and again in July and August. In more northern parts, there is only one brood, in June and July.
It is rather similar to the Dark-barred Twin-spot Carpet, and some specimens are very difficult to tell apart.
The larvae feed on low-growing plants such as knotgrass (Polygonum) and bedstraw (Galium).
