Davey, P., 2009: A species found throughout Britain, the larva feeds on gorse (Ulex europaeus) and petty whin (Genista anglica). In Dorset, the moth occurs wherever gorse is abundant, particularly on heathland, but also on gorse-clad chalk downland. The record below refers to a strong colony of July Belle on an unimproved neutral grassland site where there is no gorse. However, dyer's greenweed (Genista tinctoria) is well established there: Rooksmoor, fourteen disturbed by day on 4 June 1997, three by day on 5 June 2003 (P Davey).
