Sophronia humerella. Castle Eden Dene 



Pleurota bicostella. High Force 



Harpella bractcella. This species was recorded as 

 British in the E. W. I. (iii. 179) f rom 

 specimens taken and bred at Shotley near 

 Gateshead, and I took a beautiful specimen 

 at light near Throston, Hartlefool in June 1 880. 

 It is therefore widely spread in the county, 

 but not enough is known of its habits for it 

 to be often taken. I believe less than a 

 dozen British specimens exist, all from 

 Durham but one. The larva feeds on rotten 

 wood
