on the leaf and flower buds which they destroy. Later in the sea- 

 son the new brood feeds on the epidermis of the leaves. The in- 

 juries from the species are due to the destruction of the fruit buds 

 and to the deformities induced by the eating ofif of terminal buds. 



The adult is a moth somewhat resembling the codling moth. The 

 eggs are laid on the foliage about the first of July. The winter is 

 passed as a partly grown larva in a hibernaculum constructed for the 

 purpose. These hibernacula are very difficult for an inspector to 

 detect and the insect is one that may readily be distil' -uted on nurs- 

 ery stock, scions, etc. 



The bud moth has been periodically injurious *n the East. In 

 another part of this report are notes on the life-hisi ry and means 

 of controlling its ravages. 



The species occurs at Missoula where it has been very injurious. 

 I have also found it on a few trees twelve miles up the Bitter Root 

 Valley and for a short distance up the Rattlesnake V^alley. 



A reasonably complete account of this insect \^^as given m the 

 First Annual Report of the State Entomologist, (ic,v'v-:).
