Davey, P., 2009: A rare species that has declined since the 1950s in southern England, still headquartered in the New Forest, with small colonies elsewhere in Hampshire, Wiltshire and Sussex, the larva feeding nocturnally, firstly on the flowers and buds, and then on the foliage of oak (Quercus spp.). In Dorset, the moth was noted from two old oak woodland localities in the nineteenth century. More recently, the 1978 and 1982 records occurred in similar weather situations with sluggish airflows circulating around nearby low-pressure centres. These were likely to have been dispersed examples either from southern England or from northern France. It is very doubtful that the species is still resident given the destruction of so much old oak woodland, but targeted sugaring is recommended for this species in Boys Wood, Rye Hill Wood and Castle Hill Wood. The moth may occasionally be observed flying over the oak canopy during the afternoon on hot days: Middlemarsh, wings found on 13 July 1886 (J Dale), Cranborne, occasionally (Reverend F Fisher), Arne Wood, at MV on 4 August 1978 (B Pickess), Highcliffe, at MV on 4 August 1982, plus two subsequently (E Wild).
