Scientific name: Macrothylacia rubi

May - June. Britain and north and west Ireland. Large brown moth found on heathland, downland and coastal grassland.

This moth is named after its colouration; males are usually foxy-red/brown and females grey-brown.  However, moths from cooler upland areas tend to be darker and less red than those from southern areas.  Females are larger with considerably longer forewings and lack the feathered antennae of the males.  This moth can be distinguished from similar species by the absence of a central white spot on the forewing. The male flies rapidly on sunny afternoons just above the ground searching for females which are nocturnal.
