MOTHS. 315 



in crawling back to the tree, find a convenient 

 shelter under the hessian, and there pupate. This 

 bandage must be carefully watched, taken off at 

 regular intervals, and the grubs or pupae under it 

 crushed and the bandage re-tied. If this is not 

 done, it might form a breeding-ground for the pest 

 instead of acting as a preventive measure. 



The cherry-tree borer {Cryptophaga unipunctata) 

 The larva of this moth bores holes and lives in the 

 stems of the pear or cherry tree. The tunnel acts 

 as a shelter by day, but at night the caterpillai' 

 comes out and feeds on the leaves. It pupates in 

 the tunnel. The moth is a soft, creamy- white insect 

 measuring about 14 inches across the outstretched 

 wings. The only ornamentation is a black spot in 

 the centre of the front pair.
