vie.ws of a pnpa 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 t joth-like 

 processes directed caudad. 



The moth. — The 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 wino^s. Dr. Harris 

 saw the resemblance to two eye-like 

 spots in the arrangement of two 

 short horizontal black dashes fol-

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 ajypearance and habits in the spring. — 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 

 earliness or lateness of the season or of the variety of the tree in-

 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-
