The moth is out in May and June, earlier in some districts. In the daytime it may be seen on the trunks or boughs of trees, most frequently at too great a height to be easily secured; but still a few sit low enough for capture, especially on the trunks of fir trees. The species is a decidedly local one, and seems to be largely confined, in Britain, to the southern parts of England, Wales, and Ireland. It occurs in some of the woods of Kent, Surrey, Sussex, Hampshire, Dorsetshire, Devonshire, Cornwall, Gloucestershire, Oxfordshire, Buckinghamshire, Bedfordshire, Essex, and Suffolk. Edwards notes the species as rare at Malvern, Worcestershire. Forsythe, in "A List of the Macro-Lepidoptera of Lancaster and District" (_Entom._ 1905, p. 12), states that the moth may be found sitting on the fir-tree trunks at the end of May, at Witherslack and Quernmore; and a single specimen has been recorded from Upton, near Birkenhead, Cheshire. The occurrence of _T. consonaria_ in the north of England seems open to question. The only county in Wales appears to be Glamorganshire, as mentioned by Barrett. Kane (_Catalogue of the Lepidoptera of Ireland_) noted the species from Derrycunihy, and Mucross, Killarney, where he has taken it in moderate abundance; he also gives Clonbullogue, in King's County. The range abroad extends to Amurland and Japan. GREY BIRCH (_Tephrosia punctularia_). Three examples of this greyish species are shown on Plate 137. The wings are usually whitish grey in the ground colour, and sprinkled or dusted with darker grey; there are three blackish, or black dotted, cross lines on the fore wings, often indistinct, but rarely entirely absent, and even then represented by black marks on the front margin. Sometimes the first and third lines may be well in evidence and the central one absent; occasionally the second line is placed quite close to the first; the sub-marginal line is whitish, inwardly shaded with dark greyish, especially at the middle and towards the front margin. The hind wings have two cross lines corresponding with the first and third on the fore wings. There is a good deal of variation in the amount of dark speckling, and this is occasionally so heavy that the insect becomes dark grey in colour; I have taken such specimens at Oxshott in Surrey. Dark aberrations are perhaps more frequent in the north of England, but the species is more local and less plentiful in that part of the country. [Illustration] 2 Pl. 136. 1, 2. BRUSSELS LACE. 3, 4.
