white. On the fore-wings are two yellow bands, one near 

 the base and the other beyond the middle, each bordered on 

 both sides by rows of black spots, which may be more or 

 less confluent. There is usually a row of black spots in the 

 central area, and another on the hind margin. The hind- 

 wings have an incomplete central row of spots, sometimes 

 connected by a faint yellow line, and another row on the 

 hind margin. The moth varies considerably, and the black 

 spots may almost disappear, or may be much more heavily 

 marked than usual. 



The larva feeds on currant, raspberry, gooseberry, &c. It 

 is creamy white, with transverse black dorsal spots, black spots 

 on the sides, and an orange-coloured spiracular stripe. The 

 body is covered with short fine hairs. The pupa is dark 

 reddish-brown, or nearly black, with orange stripes. 



The moth appears in July and August, and is common in 

 almost every garden.
