middle of the back is a series of purplish-edged, brown-centred, 

 whitish, triangular markings ; the third ring is swollen, and has 

 a black collar. It feeds at night on the foliage of red and 

 black currant, also on gooseberry, and may be found in April 

 and May, earlier or later according to season, sitting by day 

 upon the bushes. 



The moth flies in July and August, and occurs in gardens,

 always more or less local, although it is distributed over the 

 greater part of the British Isles.
