Adults are pale reddish-brown in colour with slightly paler hindwings and a shiny appearance, hence the common name (3). The caterpillar has a pale brown back, becoming greener towards the underside (3).
The Pale Shining Brown is a single-brooded species, the adults of which are on the wing from mid-June to mid-July. The precise details of the life history of this moth have yet to be elucidated in the wild, however the caterpillars will feed on dock, dandelion and other herbaceous plants in captivity (1). It is likely that the overwintering stage is the caterpillar (1).
The Pale Shining Brown moth was once widespread in England south of the Severn and the Humber, however it has been recorded from just 20 sites since 1980 (2) and is now recorded with any regularity from just two or three localities (4). A greyish form occurs occasionally as a migrant into south-east England (5). It is known from most other European countries (2).
The Species Action Plan for the Pale Shining Brown moth, produced as part of the UK Biodiversity Action Plan (UK BAP) aims to maintain the current known populations and enhance these by 2010. Suggested action includes increasing the amount of suitable habitat available at occupied sites and linking fragmented sites. Survey work and research into the causes of the decline and habitat needs of the species have also been proposed (2).
