This species is found in Northern and Central Europe and 

 Northern Asia. It expands about an inch and a quarter. 



The fore- wings are white, and the base chocolate-brown, 

 with two steel-blue transverse lines. In the central area is a 

 small brown dot. Beyond the middle of the costa is a broad 

 angular brown spot ; this forms the commencement of a sub- 

 marginal band, which is intersected by white or brownish lines, 

 most distinct towards the hind margins. The marginal band is 

 suffused with bluish-grey, with a white zig-zag line passing 

 through the middle. The fringes are brown and white. The 

 hind-wings are white, with a small brown central dot, a dotted 

 brown sub-marginal line, and a bluish-grey marginal band 

 intersected with white on its inner half. The fringes are grey 

 and white. The larva lives on raspberry and bramble from 

 July to September. It is green, with a series of red dots on 

 the head, and on the sides of the three succeeding segments. 

 On each segment from the fifth to the tenth is a bright reddish 

 triangular spot on the back near the incisions, the apex pointing 

 towards the head, bordered with dark brown, and with a 

 dark brown tapering streak through the middle. There is a 

 whitish spiracular line. 



The pupa is shining chestnut-brown, with dark ochreous 

 brown on the face, wing-cases, back, and incisions. The 

 extremity has two small curved points.
