trees of their parenchyma. While it does not appear to have 

 wrought great destruction generally, nevertheless there are in- 

 stances on record where 

 it has done much damage 

 in orchards. The larvae 

 have the habit of form- 

 ing their cocoons in com- 

 pany, attaching them to 

 the twigs in great clus- 

 ters, as represented in 

 Fig. 251. This fact has 

 led to the recommen-

burned. As the cocoons are located at the ends of the twigs, this 

 may be a partially effective remedy. Another remedy is to 

 thoroughly spray the trees with coal-oil emulsion or with linseed- 

 oil. The greasy application is said to destroy the pupae in the 

 thin papery cocoons.

There are several species of Tineid insects which attack gar- 

 ments made of woolen fiber and furs. One of the commonest 

 and most widely distrib- 

 uted of these is the insect 

 which we are now consid- 

 ering. In Pennsylvania and 

 in Maryland and south- 

 ward, so far as observation 

 shows, this is the common- 

 est of the ' ' Clothes-moths. " 

 The damage, it is needless
