Morley's Final Catalogue: Referring also to Brown-spot pinion: In profusion on sugar and ivy-blossom everywhere from Bentley to Burgh Castle. The latter at Wingfield, and abroad till 5 November 1932 at Monks Soham; Mildenhall in 1936.
Recent Suffolk Status: Common.
Life history: Single-brooded. Can be seen at light in large numbers at some sites. Occasionally recorded at Ivy blossom.
Identification: It is very variable in appearance with several named forms; care should be taken as some forms superficially resemble forms of Lunar Underwing (Omphaloscelis lunosa) however the slimmer oval and kidney marks should help identification. The similar Brown-spot pinion has black marks along the costa - these are brown in Beaded chestnut.
Habitat: Woodlands, scrub, hedgerows, heathland and gardens.
