The species occurs most frequently in the New Forest, Hampshire, where, in some years, it is very common. Other English counties in which it has been found, or still exists, are—Devon (Cann Woods), Dorset (Cranborne and Bloxworth), Wilts. (Savernake Forest), Sussex (Abbots Wood, Charlton Forest, Holme Bank, etc.), Surrey (Addington, June, 1902), Kent, Essex (Epping Forest), Berks., Bucks., Warwick (Princethorpe Wood), Worcester (Wyre Forest), Stafford (Cannock Chase), Cheshire (Dunham Park), York (wood near Selby), Lancashire (Corporation and Quernmore Woods).

Pale Oak Beauty (Boarmia consortaria).

Some specimens are rather greyer, and the cross markings are occasionally less distinct than in Figs. 1 ♂, and 3 ♀ on Plate [135], which represent the typical forms of this species in England. Examples of a blackish form have been noted from a wood in West Kent, and these are apparently referable to the melanic ab. humperti, Humpert, but the Kentish specimens I have seen had the second line of fore wings edged with white, and a white submarginal line.

The caterpillar, which in shape is somewhat like that of the last species, varies in colour. One form is greenish grey, with three lines, the central one darker than those on each side. In another the colour is pale brown mottled with reddish and a darker brown. It feeds on oak, birch, and sometimes sallow, in July and August.

The moth is out in June and July, and specimens have been recorded as captured in September. It may be found on the trunks of oak and fir trees, and will come to sugar and light at night. Although local it is not uncommon in the New Forest and other woods in Hampshire; also in Sussex, Surrey, Kent.
