The imported or common currant worm occurs in this family, 
a well-known pest of currants and gooseberries, stripping the leaves 
from the bushes if not promptly checked. It is particularly destructive 
in that its attacks are fre- 
quently not observed until 
too late to save the foliage. 
The yellow-spotted willow 
slug, Nematus ventralis 
Say, is a common pest of 
the willow. The larva is 
dark with yellow spots.
