4 LEPIDOPTERA. 



Larva brownish flesh-colour ; head, dorsal plate, and front 

 feet dark brown ; anal plate broad, darkest at its upper 

 edge ; spots of the ground colour only visible by appearing 

 rather rough. 



May and June ; on larch {Finns larij"), drawing together 

 the fine needle-like leaves and eating down them from 

 the tips, then removing to another fascicle of leaves. (A. 

 Balding.) 



Pupa in the latest larval habitation. 



The moth hides during the day in larch trees, or if driven 

 out of them by a rough wind will sit on a fence or a tree 

 trunk, or any adjacent shelter. It will fly gently in the day- 

 time if beaten out, but at early dusk flies vigorously over the 

 larch trees, rather high up. Probably in larch plantations 

 in all parts of England, since it is recorded from Kent to 

 Devon, and to Norfolk ; also in Herefordshire, Worcester- 

 shire, Leicestershire, Yorkshire, and Westmoreland, but not 

 j^et recorded from Wales or Ireland ; and in Scotland only in 

 Perthshire, where it was taken by Sir Thomas MoncriefE at 

 Moncrieff Hill. Abroad it is known to inhabit Central 

 Europe.
