May, in the terminal buds of strong young trees of Pinioi 

 picea, noticeable by the loose hanging scales. Also on F. 

 siiiithiana , which it appears especially to frequent when 

 planted in this country ; and F. ccphalonica. 



The moth is a rather quiet, sluggish species, and frequents 

 silver spruce and introduced firs in gardens and other sheltered 

 situations ; but will fly about them a little when disturbed, 

 quickly hiding again in the same trees. At sunset, however, 

 it flies about the tops, out of reach. A very local species, 

 but to be found in favoured spots in Kent, Surrey, Hants, 

 Dorset, Wilts, Berks, Oxfordshire, Herts, Suffolk, Norfolk,
