REPORT OF THE STATE ENTOMOLOGIST I9O7 Q.J 



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. 



A single parasite, Macrocentus iridescens French, 

 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- 

 cund a Fabr. should apply equally to this pest.
