270 LEPIDOPTERA. 



On the wing in May and June, and, rarely and very locally, 

 in August. 



Laeva when full-grown rather over five-eighths of an inch 

 in length, stout, the head horny, globular, and stuck like a 

 knob on the rather smaller second segment ; the skin granu- 

 lated in appearance ; the head and body covered thickly 

 with short fine pale hairs ; colour pale ochreous-green, with 

 the second segment pinkish, and a faint reddish tinge over 

 the back of the other anterior segments ; a thin dorsal, and 

 somewhat broader subdorsal line nearly of the ground 

 colour and indistinct ; and a faint spiracular line : or else 

 pale brown or pinkish brown with the lines a little darker ; 

 head dark purplish brown, with the upper lip paler. On 

 first emerging from the egg it is of a very pale green, with 

 head and collar shining black, bristles pale, long on the head 

 and last segment, bifid and recurved on the remaining seg- 

 ments. When a little older pale purplish pink, with the head 

 still black ; and when half an inch long pale green, or brown, 

 with short straight bristles, the bifid hairs having disappeared.

On liub'us fruMcosus (bramble), B. idcvus (raspberry), 

 Fragaria vcsca (strawberry), Potcntilla fragariastrum (barren 

 strawberry), and P. reptans. June to September. The Rev. 

 J. Hellins says that it is very sluggish, and always lives, as 

 far as possible, concealed. It at first stations itself on the 

 upper surface of a leaf, near the midrib, and spins several 

 silken threads above itself for a covering, eating away the 

 upper surface of the leaf. When older it still chooses the 

 upper surface of a leaf, but forms its covering by drawing 

 down another leaf over it, fasteuing the edges, here and 

 there, with stout threads, and feeds in the cave thus formed ; 

 spends nearly all its time in this habitation, except that, when 

 necessary, a new one is formed. He also says that he found 

 stunted brambles, with small leaves, to be especially favoured ; 

 but that Mr. W. H. Harwood afterwards discovered that
