Rusty Tussock Moth 



Notolophus antiqiia L. 



This insect, sometimes called the antique moth, is a European pest now known 

 to be present in northeastern United States and southeastern Canada and also 

 on the Pacific Coast. It attacks the foliage of several deciduous orchard and shade 

 trees and is reported to feed on some coniferous evergreens, but usually is not 

 abundant enough to cause serious injury. 



Its life history is similar to that of the white-marked tussock moth except that 

 the eggs laid on the cocoons are not covered with froth}- material.

The full-grown caterpillars may be distinguished from those of the white- 

 marked and other tussock moths by their black head, darker body, and the 

 presence of two additional pencils of long black hairs, one on each side, about 

 midway of the body. 



The female moth is gray and wingless. The male is rust-brown and has wings, 

 the front pair being crossed by two darker bands and bearing a conspicuous white 

 spot near the rear border. 



Control measures are the same as those recommended for the white-marked 

 tussock moth.

Satin Moth 



Slilpnotia salicis Linn. 



The satin moth, which is a native of Europe, was first found in the United 

 States near Boston in 1920. Since then it has spread throughout Massachusetts, 

 Rhode Island, most of Connecticut, southeastern New Hampshire, and south- 

 western Maine. Localized infestations have been reported in eastern Canada 

 and there is also a large infestation on the West Coast in British Columbia and 

 the State of Washington.
