REPORT OF THE STATE ENTOMOLOGIST 1907 2 
_ Food plants. This species is evidently somewhat of a general 
feeder. Among shade trees, it evinces a marked fondness for 
linden, horse-chestnut, maple and elm, while in the forests beech, 
hickory and chestnut are seriously damaged. It has also been re- 
garded as quite destructive to apple under certain conditions and 
has been recorded as feeding on birch. 
Distribution. ‘This species is evidently widely distributed in 
_the eastern United States at least, having been recorded from Nova 
Scotia south to Georgia and westward to Colorado. 
Natural enemies. The English sparrow is a most effective 
check on this species in cities and it is presumable that a number 
of our native forms feed upon the caterpillars in the country. It 
is very probable that the large reduction in bird life in recent years 
is responsible in considerable measure for increasing depredations 
by this and other insects. The better protection of native birds 
must be regarded as one of the most efficient means of preventing 
insect outbreaks in forests. 
Emcinglemparasite  Whaenocentus trirdescens), Krench, 
has been reared from this species, though undoubtedly other 
parasitic enemies as well as a number of predaceous forms, prey 
upon it. : 
Preventive measures. The preventive measures discussed in 
the account of the green striped maple worm, Anisota rubi- 
cunda Fabr. should apply equally to this pest.
