from holes in needles to other nearby needles. Webbing area is 
expanded from July to September. Entire trees up to 8 feet tall 
may be completely webbed (fig. 157). Winter is spent in the larval 
stage in a silken case. The larvae resume feeding in the spring, 
becoming full grown and pupating from mid-May to early June 
(569). Trees grown as ornamentals or in permanent plantings 
may be seriously damaged by this species. The cutting out and 
removal of webbed masses of foliage is a helpful control practice. 
Fascista cercerisella (Chambers) feeds on redbud from Dela- 
ware and Maryland to Illinois and southward. The adult is velvety 
black except for its white head and a white collar. The forewings 
are slightly bronzed and marked with three costal spots and 
several white terminal points. The larvae feed on leaves which 
they web together. There are at least two generations per year. 
Battaristis vittella (Buseck) is widely distributed throughout 
eastern United States and southern Canada. It has been reared 
from the buds of mugho pine; from the cones of Scotch, Austrian,
