About the same time Mr. A. B. Cordley, entomologist of the Oregon 
Experiment Station, was also investigating the habits of this insect, 
his account comprising a description of the injury to peach and prune 
twigs in early summer, and the work of similar larve in strawberry 
beds in October, the latter larve wintering in the crowns of the plants. 
HISTORY AND DISTRIBUTION. 
The peach twig-borer is apparently an Old World species and probably 
avery ancient enemy of the peach, with little doubt coming with this 
fruit from western Asia. It was described in Europe in 1859, and in 
this country in 1860. The American species was afterwards shown to 
be identical with the European peach moth. As an important injurious 
insect in this country, attention was first drawn to it about 1872 by 
Mr. Glover, a former entomologist of the Department, and also by Mr. 
Saunders, of Ottawa, the report of Mr. Glover being the first published. 
Glover’s report describes excessive damage by it as a twig-borer in 
young peach orchards in Maryland, and Saunders’s report, while relat- 
ing chiefly to marked injury by a crown-borer in strawberry beds (now 
known to be a different insect), refers also to injury to the peach twigs 
yn Ontario. Some years later, Prof. J. H. Comstock, while entomologist 
of the Department, reported considerable damage from the peach twig- 
oorer in Virginia and in the District of Columbia, and first noted the 
peculiar fruit inhabiting brood. Later the insect was made the subject 
of an article by Dr. J. A. Lintner, in which it is reported to have occa- 
sioned damage to peaches in several localities in the State of New York. 
We also have accounts by Prof. C. V. Riley, of injury to strawberry 
plants in Illinois, referred by hin to Anarsia lineatella, and also articles 
on this insect, particularly as a strawberry miner, by Prof. S. A. Forbes. 
Very great damage to peaches in Kent and Sussex counties, Del., was 
reported later by Riley and Howard. 
On the Pacific slope record was made of injury by it to various stone 
fruits by Mr. Coquillett, and later similar damage was reported from 
Vancouver. We have also the results of the investigations by Mr. Ehr- 
horn in California, and the recently published accounts by Mr. Cordley 
relative to the insect as affecting peaches and prunes in Oregon, and 
also in strawberry beds—a similar but undoubtedly distinct insect. 
That this twig-borer is very destructive to the peach, plum, apricot, 
and almond in western Colorado is shown by recent accounts, and 
damage from it has al-o been lately reported in West Virginia. 
In addition to the more important published accounts, injury from the 
twig- borer has been often recognized and reported by various observers 
in recent years. Nearly all these reports refer to the injury to twigs of 
stone fruits, and very few to the strawberry, the allied insect which 
infests the latter either being more rare or less often observed. Th« 
records of this Department show the presence of the twig-borerin at 
least twelve States, and give it a range which indicates that it is practi-
