Pack.) 
Small, velvety green caterpillars, with shining black heads, draw to- 
gether the tip leaves on uprights and feed within. The pest is com- 
monly known as the ‘‘fire worm ”’ because of the scorched appearance 
of a badly infested bog. There are two broods annually. The species 
overwinters as an egg attached to the under side of the leaf. 
Where sufficient water is available, it is an effective plan to reflow 
for two or three days when the worms are coming down out of the 
uprights and pupating. If this is not feasible, the only satisfactory
