views of a pupa are shown in figure 34. It is about .27 of an 

 inch in length and of a light brown color ; the dorsum of each 

 abdominal segment bears two transveise rows of small tooth-like 

 processes directed eaudad. 



The moth.—TiiQ moth (Fig. 35) measures about three-fifths of 



an inch across its expanded wings. 

 It is of a general dark ash-grey col- 

 or with a broad cream white band 

 across the front wings. Dr. Harris 

 saw the resemblance to two eye-like 

 spots in the arrangement of two 

 short horizontal black dashes fol- 

 lowed by 

 a vertical

Its Life-History, 



^' Although the caterpillar and pupa of the bud moth were known 

 more than eighty years ago, its true life-history, as observed by 

 Mr. J. Fletcher, the Canadian Goverment entomologist, and the 

 writer, was not recorded until 1892 (Report of Entomologist for 

 Dept. Agr. Canada, 1891, p. 195). 



Its aj>pearanGe and habits in the sjpring. — The date of the 

 emergence of the little brown caterpillars from their winter retreats 

 varies considerably in this state. They seem to time their ap- 

 pearance by the date at which the buds begin to open. Thus the

 fested will vary the time from two to four weeks, ranging from 

 April 15 to May 15. 



In some cases the caterpillar appears before the bud has opened 

 sufficiently for it to readily enter. It is then forced to eat its 

 way into the bud. Once within the bud it revels in the very ten-
