73.143 [B&F: 2378] Brighton Wainscot (Oria musculosa) (Hübner, [1808])


Notes: Nationally scarce (Na) in corn fields in parts of southern England, a priority species under the UK Biodiversity Action Plan. Originally known from Wiltshire, Hampshire and Berkshire, it was eventually found to range across parts of Gloucestershire, Somerset, Surrey, Sussex, Northamptonshire and Shropshire. Since 1980, however, it has been reported from less than 25 percent of the 10-km squares with previous records and Salisbury Plain is probably the only area where the species now occurs. In Hampshire the species spread into wheatfields in the north of the county from its stronghold on Salisbury Plain around the time of the Second World War, and became locally common. It also turned up at times in southern Hampshire. After flourishing for several years, it underwent a spectacular crash in the late 1970s, and the last record was of one at Burghclere in 1983. The reasons for its sudden extinction in the county, and elsewhere, are not known. Not recorded from the Isle of Wight since 1952. Wingspan 28-34 mm. Larva feeds on various cereal crops and grasses, over-wintering as an egg.
