The adults of this quite attractive species have a subtle pattern of red, black and grey on the upperwings.Easily recognised by the reddish admixture of the forewing, together with the broadly triangular dark patch before first line
The single generation is on the wing in July and August, when it flies from dusk into the night and is attracted to light.The larvae feed on oak (Quercus), spinning leaves together with silk.
Common in oak woodland, deciduous woodland and areas with scattered trees throughout much of England; rare in Ireland.
