Gonophora derasa, Kirby, Eur. Butterflies and Moths, p. 143

 figs. T-I b (1895). 



The Moth is of about the same size as the preceding, and 

 is common in most parts of Central and Eastern Europe, as 

 well as in Northern and Western Asia. The fore-wings are 

 yellowish-grey at the base, and are crossed by two oblique 

 white bands, one running from the costa to a little beyond the 

 middle of the inner margin, and the other from the apex to the 

 hinder angle. The triangular area bounded by these bands is 

 clouded with brown and white, and there is a transverse series 

 of parallel fine zig-zag brown lines, forming very acute angles 

 on a whitish ground. The hind margins are brown, with two 

 rows of small white arches, surmounted by an ill-defined white 

 line. The fringes are also whitish. The hind-wings are dusky, 

 slightly tinged with ochreous, and have whitish fringes. 



The larva feeds on bramble, and may be found till the end 

 of September. It is smooth, but has a few fine scattered hairs. 

 The head is large, and deep brownish-yellow like the body. 

 On the back of each segment is a coffee-brown hexagonal spot, 

 with a black line running longitudinally through it. Beneath 

 these is a line composed of blackish-brown dots, and the fifth, 

 sixth, and seventh segments have a pale yellowish spot on the 

 sides, bordered with black, and the third and twelfth segments 

 have an elevation on the back. The body is brownish-grey 

 beneath. 



The day before their metamorphosis, the larvae become 

 dingy brown. When at rest they often assume a curved 

 position. 



The pupa is greyish-black, thickened in front, with very deep 

 incisions. The terminal spine is simple. The moth appears 

 at the same time as Thyatira batis, and, like it, is fairly 

 common, without being actually abundant.
