Davey, P., 2009: A species found in England, the larva feeding on beech (Fagus sylvatica). In Dorset, the moth is locally common in beech plantation and deciduous woodland containing mature beech, but rarely seen elsewhere. The national norm is for a single-brooded species from late May to early July, with a partial second brood between mid-August and mid-October. In Dorset the first brood emerges in early-May, and a second brood follows in late June. The second brood is, on average, twice as large as the first brood. Adult moths have been trapped between mid August and early September in ten of the past twenty years, often in very warm summers. These are suspected third brood individuals, often with the usual pale-clay ground colour changed to russet (ab. strabonaria), and the dark-brown line on the fore-wing and hind-wing taking on a reddish-purple hue. In these specimens, the usually absent discal spots are apparent. The period between each brood peak in the warmest summers is roughly forty-six days.
