Life History. 



During the spring 

 these moths lay their 

 eggs, which are yellow-

 very small, on the bark 

 at or near the surface

 when found. These moths are 

 very prettily colored, and the 

 male differs most remarkably 

 from the female. Thewingsof the 

 male (see Fig. 2 a) are trauspar^

 while the fore wings of the female 

 (see Fig. 2 h) are blue through- 

 out. The abdomen in both case^ 

 is blue, but that of the female is 

 encircled by a broad orange band.
