Pale shining brown moth biology
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).
TopPale shining brown moth range
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).
TopPale shining brown moth habitat
This species is predominantly found on scrubby grassland sites, typically with calcareous soil (2).
TopPale shining brown moth status
Classified as Local in Great Britain (2).
TopPale shining brown moth threats
The reasons for the decline of the species have not yet been identified (2).
TopPale shining brown moth conservation
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).
