Apple and Thorn Skeletonizer 



Hemerophila pari a- n a Clerck 



Work on apple. The left-hand leaf shows rather serious injury 

 and rolling on the right-hand side, the middle leaf rather general 

 injur}^ and rolling on both sides and the right-hand leaf less marked 

 injury with some rolling and two cocoons near the tip of the leaf.
