THE LESSER BUD-MOTH. By E. W. Scott and J. H. Paine, Entomological Assistants, Deciduous Fruit Insect Investigations. INTRODUCTION. During the spring of 1912, while engaged in apple spraying experi- ments at Benton Harbor, Mich., the senior author noticed the work of a small larva in the buds of unsprayed apple trees. The injury inflicted by this minute insect was quite severe in a neglected orchard near the laboratory, and this insect, among others, was the most important factor in the destruction of the entire crop of fruit. From the character of the injury, the attack on the swelling buds; and the tying together of the growing leaves the damage was at once at- tributed to the eye-spotted bud-moth {Tmefocera ocellana Schiff.). In 1913 a study was made of the life history and habits of this insect, supposedly the eye-spotted bud-moth, and experiments were tried with remedial measures. The first discrepancy noticed between the habits of this insect and those of the eye-spotted bud-moth, as stated in literature, was the fact that the hibernaculse were not neces- sarily situated near the buds, but were to be found in any suitable place upon the limbs. Following this, many other even more strik- ing differences in habits were noted during the course of the season, and the fact was soon impressed upon the writers that they had to deal with an insect whose economic importance had not been recorded in the United States, The adult moths, upon submission to Mr. August Busck, of the Bureau of Entomology, were identified as Recurvaria cratcegella Busck (1903),^ a species described by him (with no indication of its life history) in 1903 from material submitted by Mr. William Dietz from Hazleton, Pa., who reared it from hawthorn {Crataegus tomen- 1 Bibliographic citations in parentliesis re
