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 larvse 
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¬ 
dation that the trees, 
when infested, should be 
lightly pruned all over in 
the fall, and the twigs 
carefully collected and 
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 ofthe “Clothes-moths.” 
The damage, it is needless 
to say, is not done by the 
Fig. 251.—-Z?. pojnifoliella. a, cocoons clus¬ 
tered upon end of twig; b, cocoon, greatly en¬ 
larged ; c , moth, very greatly magnified. (After 
Riley.)
