THE GYPSY MOTH. 91 



pupation. The male moth is brownish yellow, varying to 

 greenish-brown in color, has a slender body and expands 

 about one and one-half inches. It flies by day with a 

 peculiar zig-zag flight. 



''The female moth is nearly white, with numerous small 

 black markings, heavy-bodied and sluggish, and expands 

 about two inches. The female does not fly, otherwise the 

 spread of the gypsy moth would be most rapid. After 

 mating the moths live but a short time. The female dies 

 after depositing her egg mass (Figure 7.) The winged 

 moths take no food. All damage to foliage is caused by the 

 caterpillars." 



The eggs remain over Avinter on the trees, as already 

 described. Thus, there is but one brood or generation of 

 the gypsy moth in a year, the different stages of which in 

 their- relation to each other are shown graphically in Fig- 

 ure 9. 



In view of the fact that the brown-tail moth has also 

 recently been introduced into the state and that it is fre- 

 quently confused with the gypsy moth, the following table 

 may be of service in sharply distinguishing the two species, 

 which are totally different in habits and require different 

 methods of control:
