hibernates when nearly mature, but it resumes feeding in the spring. The moth is out in June and July, and frequents moors and mosses. Plentiful in Scotland and in the north of England, its range extends through Wales and the west of England to Devonshire, where it occurs on Exmoor and is common in some parts of that extensive area. In Ireland, recorded by Birchall as widely distributed; Kane notes it from counties Kerry, Waterford, and Galway.
The range abroad extends to Amurland and Japan.
Bright Wave (Acidalia (Sterrha) ochrata).
At one time this ochreous brown species (Plate [50], Fig. 3) was an inhabitant of the Essex coast, and was found commonly at Southend among other places. Deal and other parts of the Kentish coast are more frequently mentioned in connection with later records of the species. In the present day it is far less plentiful at Deal than formerly, but it is still to be found there. Specimens have been taken in the Isle of Wight, and one has been noted from Suffolk (Aldeburgh).
The pale ochreous brown or greyish ochreous caterpillar has three broken greyish lines on the back; it tapers towards the small head, and the skin of the body is closely wrinkled. It feeds from August to May, or a little later, on the flowers of hawk's-beard (Crepis), dandelion, coltsfoot, golden rod, etc., and in confinement it seems to accept most kinds of flowers that are offered, even when widely different. Thus, Mr. Conquest, in 1907, had some caterpillars which hatched during the first week in August from eggs laid on July 25; these were at first supplied with flowering sprays of yellow bedstraw (Galium verum), and later on with the flowers of golden rod (Solidago). Instead of hibernating, which is no doubt the normal habit in the species, some larvæ reared from the egg in confinement and subjected to fostering warmth will grow very quickly and produce moths the same year.
