The Bud Moth. 93 



Its History and Distribution. 



As the insect lias been known in Europe for more than half a 

 century before it was recorded in this country, it is, therefore, no 

 doubt an imported species. It attained economic importance in 

 Europe about 1840, and was first discovered in this country in 1841 

 in Massachusetts, where it was doing considerable damage ; by 1869 

 it had become to be " the most injurious enemy of the apple-tree, 

 next to the canker-worm, in the State." The same year it did some 

 damage in Pennsylvania, and in 1870, plum trees were attacked by 

 it in Canada. The first record of the occurrence of the insect in 

 New York State is, in 1880 in a Union Springs nursery. The 

 previous year it was found at Washington, D. C, and by 1885, it 

 had reached Nova Scotia. In 1 887, it was quite injurious near 

 Rochester, N. Y., and in 1888 and 1890, apple and blackberry buds 

 were injured in Maine. Throughout Massachusetts, New York 

 and Canada the insect appeared in very destructive numbers in 

 1891, and in Michigan in 1892. It has been found in Missouri, 

 and two or three years ago was introduced into Idaho. 



The bud moth is thus widely distributed over the New England 

 and Middle States and Canada ; it occurs as far south as Washings 

 ton, D. C, and as far west as Idaho. 



How It is Spread. 



The active moths doubtless fly readily from orchard to orchard 

 and thus the pest may slowly spread. But a much more fruitful 

 source of infestation is to be found in nursery stock. We have 

 seen the insect at work in several nurseries, and it is claimed that 

 it was introduced into Idaho on stock received from one of our 

 New York nurseries. Its manner of hibernating makes its dis- 

 tribution very easy on nursery stock. 



Its Name and Classification. 



The bud moth is closely allied to the codlin moth, and resembles 

 the latter in size and form, but differs in structure, in coloring and 

 in its habits and life-history. 



A spot, somewhat eye-like in appearance, on each front wing of 

 the moth suggested its name — ocellana — which was given to it in
