THE LESSER APPLE WORM. 51 
it. Similar larve were also received from Lachine Locks, Quebec, 
some of which, however, were working beneath the skin of the apple 
and producing large blotch mines. This is also probably the insect 
~ complained of by Mr. R. M. Palmer, in British Columbia, in a letter 
- quoted by Fletcher in this same report. In his report for 1898, page 
199, Fletcher again comments on this species to the effect that for 
many years the apple growers of British Columbia had noticed a 
small caterpillar answering in everything but size to the codling moth 
larva. The insect had been abundant, but the moth was not obtained 
until 1897, when a few were bred out by Mr. E. A. Carew-Gibson 
_and forwarded by Doctor Fletcher to this Bureau, being determined 
here as identical with Walsh’s plum moth. Fletcher records having 
_ bred this species at different times from apples and haws at Ottawa, 
_ from near Toronto, and from Lachine, Quebec. Single specimens 
had been received occasionally from Quebec and Ontario, but the 
insect had not been sufficiently abundant to attract attention. 
_ Fletcher’s observations in British Columbia in the summer of 1897, 
- and also observations by Messrs. Palmer and Carew-Gibson, led these 
i gentlemen to fear that, from the numbers of the insect that were being 
found, the species might develop into a pest of importance. The 
I ‘ ~ great ay of the injury of this insect to that done by the codling 
~ moth was noted, and also its general confusion by growers with this 
“attr species. tailor. in a ies to Doctor Fietchinr, Mr. Carew- 
Gibson reported that the insect had been found through all the lower 
~ mainland and islands of British Columbia, usually attacking apples, 
_ but occurring also quite often in plums and prunes. - In concluding 
his article Fletcher remarks that he considers it unlikely that this 
insect will ever develop into a serious pest of apples and plums, and 
regards its injury in British Columbia during the years mentioned 
iy as exceptional and due to the failure of wild crabs to produce fruit. 
In Bulletin No. 61 of the Minnesota Agricultural Experiment 
Station, page 295 (1898), Lugger, under the caption “ The apple 
bud moth,” presents a brief note, stating that in addition to the 
apple this insect infests also the plum and cherry, and can become 
decidedly destructive by eating the buds of apple before they expand, 
causing in this way more injury than if the leaves were eaten. The 
-darve are said to have the habit of feeding inside of cherries, thus 
causing them to drop. 
In his report for 1900 Fletcher states, on the authority of R. M. 
) Palmer, that this insect occurred in nearly all the fruit-growing dis- 
__ tricts of British Columbia except the Okanogan Valley, but in smaller 
numbers than in 1898-99. 
\ Without question the larva of this insect is the one referred to by
