Oriental Moth 



Cnidocampa flavescens Walk. 



Cocoons of this moth, which is native to the Orient, were first found in the 

 vicinity of Boston in 1906. Since then it has spread slowly into the surrounding 

 area of eastern Massachusetts. The larva, which is one of the slug caterpillars, 

 feeds on the foliage of several trees. Norway maple, sycamore maple, buckthorn, 

 black birch, wild and cultivated cherry, apple, pear, and plum are most severely 

 injured. When the caterpillars are abundant, less favored hosts such as oak, other 

 maples, poplar, willow, honey locust, hickory, and hackberry are attacked.
