The range of this species abroad, and also that of the last, extends to Amurland.
Tawny-barred Angle (Semiothisa liturata).
The more frequent forms of this species are shown on Plate [119], Figs. 9, 10. In some examples the cross lines are almost absent, but in others they are very distinct and blackish in colour; the orange yellow band in the outer marginal area varies in width and in strength, but it is usually present, even in the sooty brown form ab. nigrofulvata, Collins (Plate [61], Fig. 7), described from Delamere, Cheshire, also found in Shropshire, and recorded from "Oakley Wood."

The caterpillar (Plate [123], Fig. 2) is green, with white or creamy transverse lines and stripes; head, reddish. Another form is pale ochreous grey or brownish, with pale grey lines and stripes; head, almost black, with purple tinge. It feeds on the needles of Scots pine (Pinus sylvestris), in July and August, and occasionally in September and October. A photograph of the chrysalis by Mr. H. Main, enlarged to twice natural size, is shown on Plate [123].
The moth is to be found in fir woods, where it lurks among the branches or sits on the trunks, or on the fallen needles on the ground. The moths of the first generation appear in June and July and, where it occurs, the second flies in August and September. Widely distributed over the British Isles, but not noted north of Moray, in Scotland.
